3M PPS 2.0 Spray Gun Adapter #S9 Review: Is the 26016 Adapter Worth Buying?

Switching to the 3M PPS 2.0 cup system is simple only when your spray gun has the right adapter. The 3M PPS 2.0 Spray Gun Adapter #S9, 26016 gives you a 16 mm male, 1.5 mm thread connection for compatible guns, but that thread spec matters more than the product name. This review answers the practical question: should you buy this adapter for your shop, or should you keep checking the compatibility chart first?

The short answer is that this is a strong buy when your gun matches the S9 fit. You get a stainless steel adapter, a wide four-point lid connection, and access to the cleaner PPS 2.0 workflow. The main tradeoff is simple: it is not universal, and it does not include the PPS cup, lids, liners, or sealing plugs.

Key Takeaways

• The 3M PPS 2.0 Spray Gun Adapter #S9, 26016 uses a 16 mm male, 1.5 mm thread for compatible spray guns.
• Its stainless steel construction helps with durability and solvent resistance in professional paint settings.
• The wide base and four-point lid-to-gun connection are designed to improve cup stability while spraying.
• The adapter lets you use PPS 2.0 cups with your existing gun only when the gun appears on the correct 3M adapter chart.
• The adapter does not include PPS 2.0 cups, lids, liners, filters, or sealing plugs, so you need those parts separately.

What Is the 3M PPS 2.0 Spray Gun Adapter #S9?

The 3M PPS 2.0 Spray Gun Adapter #S9 is a small but important connector for the 3M PPS Series 2.0 Spray Cup System. It converts compatible cup spray guns so they can connect to PPS 2.0 disposable cup lids. The #S9 version is the 26016 adapter with a M16x1.5 male thread.

This adapter sits between your spray gun and the PPS 2.0 cup assembly. It is not a spray gun, cup kit, or liner kit. Its job is to give your compatible gun the right connection point for PPS 2.0 lids, which use a redesigned connection and a wider platform for better stability.

The standout detail is the four-point connection. Instead of relying on a narrow contact point, the adapter and PPS 2.0 lid design create a wider 360-degree platform. In real shop use, that matters because a more stable cup connection feels better when you are moving around panels, changing spray angles, or working quickly between coats.

Who It’s For

• Automotive painters whose exact gun model appears on 3M’s S9 or 26016 adapter chart.
• Shop users who already own a favorite spray gun and want to add the PPS 2.0 cup workflow without replacing that gun.
• Painters doing frequent color changes, primers, sealers, clearcoats, stains, varnishes, gelcoats, or sprayable adhesives with compatible PPS 2.0 components.

Who Should Skip It

• You should skip it if your spray gun needs a different PPS 2.0 adapter size, such as 3/8 inch male, 16 mm female, or another thread type.
• You should skip it if you expect a complete starter kit, because this product includes the adapter only.
• You should skip it for casual home use if you cannot meet 3M’s industrial and occupational safety requirements.

Key Features and Design Highlights

Thread Fit and Compatibility

The most important spec is the 16 mm male, 1.5 mm thread. If your spray gun does not match that thread and adapter type, the #S9 is the wrong part. 3M’s adapter guide lists S9/26016 for select models, including Accuspray PerforMax 05-100 Primer, several ATD Leonardo models, and multiple Astro Euro HE and HV models.

That compatibility chart matters because PPS adapters can look similar at a glance. Amazon’s available size options include many thread sizes and adapter styles, such as 1/4 inch, 3/8 inch, 8 mm, 10 mm, 12 mm, 14 mm, 16 mm, and 18 mm variants. You should match your gun model and thread before ordering, not just the adapter number in a forum post or product review.

Stainless Steel Construction

The #S9 adapter uses stainless steel. That is the right material for a part that sees coatings, cleaning solvent, and repeated cup changes. A lower-grade adapter can save money upfront, but damaged threads or poor solvent resistance can cost you time during a job.

The adapter is also silver, compact, and simple to inspect. Before each job, you can check the threads, clean the bowl area, and confirm the PPS 2.0 lid locks cleanly. That quick inspection helps you catch dried material or thread damage before it affects spray setup.

Four-Point Connection and Wider Platform

3M designed the PPS Series 2.0 adapter with four points of connection from lid to gun. The wider 360-degree platform helps the cup feel more stable while spraying. That is useful when your cup angle changes during panel work, boat touch-ups, furniture finishing, or equipment repainting.

This feature does not improve atomization by itself. Spray quality still depends on your gun, tip setup, air pressure, coating, filter mesh, and technique. What the adapter improves is the connection between your gun and the PPS 2.0 cup assembly.

Wide Bowl Design for Easier Cleaning

The adapter’s wide bowl design is made for easier cleaning after use. You still need to wipe or rinse it according to your coating and solvent process. The benefit is access: a wider bowl gives you fewer awkward edges where paint can collect.

The bigger cleaning advantage comes when the adapter is used with the full PPS 2.0 system. With disposable lids and liners, 3M states that the system can use up to 70% less cleaning solvent and shorten prep and cleanup time by as much as 50% compared with conventional systems. That claim applies to the PPS 2.0 system, not the adapter by itself.

Performance, Compatibility, and Efficiency

Performance is mostly about fit, stability, and cleanup. When the #S9 is the correct adapter for your gun, it lets you use your existing spray gun with PPS 2.0 cups. That can be more cost-effective than buying a different gun just to use the cup system.

The adapter is a good fit for painters who value fast changeovers. PPS 2.0 cups let you mix, measure, filter, spray, and temporarily seal coatings inside the system. The adapter does the connecting work, while the cup, lid, liner, and filter do the material-handling work.

For efficiency, focus on the entire setup. The #S9 adapter gives you access to the PPS 2.0 workflow, but you need the correct PPS 2.0 cup size, disposable lids and liners, and the right filter mesh for your coating. 3M lists PPS 2.0 cup sizes of 3 oz, 6.8 oz, 13.5 oz, 22 oz, and 28 oz, so you can choose the cup size that fits the repair instead of overmixing material.

How It Performs in Real Use

For Automotive Spot Repairs

For small repairs, the #S9 is useful when your compatible gun already sprays the way you like. You can keep that gun and add the PPS 2.0 cup system for primers, sealers, basecoats, or clearcoats. The 16 mm male, 1.5 mm thread must match before you start the job.

For Multi-Color Panels

For multi-color panels, the main benefit is faster workflow with less cup cleaning. The adapter stays on the gun, while the PPS 2.0 disposable liner and lid system handles each paint mix. That makes sense when you are switching between small batches and want fewer traditional cup cleanups.

For Boats, Furniture, Equipment, and Shop Projects

The listing names cars, boats, furniture, equipment, home, arts, and crafts as suitable PPS 2.0 project categories. The adapter can support those jobs when the coating and spray gun are appropriate. For marine or industrial coatings, you should also follow the coating maker’s filter, solvent, ventilation, and PPE guidance.

Use Cases, Maintenance, and Safety Notes

Common uses include automotive refinishing, marine touch-ups, furniture finishing, equipment paint, primers, sealers, clearcoats, gelcoats, stains, varnishes, and sprayable adhesives. The adapter does not change your spray gun’s needle, nozzle, or air-cap performance. It simply lets the right gun connect to PPS 2.0 components.

Maintenance is straightforward. After use, clean coating from the bowl area and threads before it cures. Inspect the M16x1.5 threads for damage, check that the cup lid connection feels secure, and avoid forcing the adapter into a gun that does not thread cleanly.

Safety matters because 3M labels this product for industrial and occupational use. You should use proper ventilation, respirators, gloves, eye protection, and coating-specific safety procedures. You should also follow OSHA, ANSI, shop, and coating-maker requirements where they apply.

Pros and Cons

Is It Worth the Price?

The #S9 adapter is a strong value for the price when it is the exact adapter your spray gun needs. It gives you access to the PPS 2.0 system without buying a new gun. For a shop that already uses PPS lids and liners, that can make it a smart buy for everyday use.

The value drops quickly if you are guessing on compatibility. Buying the wrong adapter wastes time, creates return hassle, and can delay a paint job. Before you order, compare your gun model against 3M’s adapter chart and confirm that you need S9, 26016, M16x1.5.

You get the most value if you already own PPS 2.0 cups or plan to buy a PPS 2.0 starter kit. If you only need one simple paint job and do not already use disposable cup systems, a complete kit may be the better starting point.

How It Compares to Alternatives

The closest alternatives are not really competing brands first, but other PPS 2.0 adapter sizes. For example, a 3M #S15 adapter uses a different thread format, while other PPS 2.0 options cover 16 mm female, 3/8 inch male, 1/4 inch male, and more. The #S9 remains the right choice only when your gun needs the 16 mm male, 1.5 mm S9 fit.

Aftermarket adapters can cost less, but the main reason to choose the genuine 3M adapter is confidence in fit, stainless construction, and connection design. If you spray often, the official adapter is easier to justify. If you spray rarely, confirm the total cost of the adapter plus PPS 2.0 cups before deciding.

Frequently Asked Questions

Does the 3M PPS 2.0 Adapter #S9 fit every HVLP or LVLP spray gun?

No. The #S9 fits spray guns that match the S9 adapter type and M16x1.5 thread. You should check 3M’s adapter chart for your exact gun model before ordering.

What comes in the box with the 3M 26016 adapter?

The Amazon listing identifies the included component as the adapter. It does not list PPS 2.0 cups, lids, liners, filters, or sealing plugs as included parts.

Can this adapter reduce solvent use by itself?

No. The solvent and cleanup savings come from using the adapter with the full PPS 2.0 disposable cup, lid, and liner system. The adapter is the connector that lets a compatible gun use that system.

Which PPS 2.0 cup sizes can I use after installing the correct adapter?

3M lists PPS 2.0 cup sizes of 3 oz, 6.8 oz, 13.5 oz, 22 oz, and 28 oz. Choose the cup size based on your repair size, coating volume, and shop process.

Is the #S9 adapter safe for solvent-based and waterborne products?

3M describes the PPS 2.0 system as suitable for solvent-based and waterborne products when used with the correct lids and filters. You should still follow the coating manufacturer’s filter mesh, solvent, PPE, and ventilation guidance.

How should you maintain the adapter?

Clean the bowl and threads after use, especially before coating dries on the stainless steel surface. Inspect the M16x1.5 threads and lid connection before each job, and do not force the adapter into a spray gun that does not thread smoothly.

The Bottom Line

The 3M PPS 2.0 Spray Gun Adapter #S9, 26016 earns an 8/10 because it is durable, specific, and useful when your spray gun needs the S9 M16x1.5 fit. You should buy it if your gun is confirmed compatible and you want to use PPS 2.0 cups without changing guns. You should look elsewhere if you need a complete starter kit, a different thread size, or a consumer-use paint setup.
