Frequently Asked Questions
Will These Grommets Come in Different Colors?
No; the seller typically offers standard black grommet colors only. The reviewer notes limited aesthetic options, so buyers should expect minimal grommet colors variety and prioritize fit and durability over cosmetic choices.
Are They Resistant to Oil and Fuel Exposure?
Yes; an initial test diagram suggests hydrocarbons cause minimal swelling. He notes grommet durability remains good under light oil and fuel exposure, indicating adequate fuel resistance for typical engine bay vibration isolation.
Do They Fit Older Classic Car Models?
They may fit some older vehicles; the reviewer advises checking classic car compatibility and vintage vehicle fitment against OEM sizes and part numbers. Compatibility depends on grommet type, dimensions, and specific classic model requirements.
Are Replacement Individual Grommets Sold Separately?
Surely sold separately. The reviewer reports that grommet compatibility varies; retailers sometimes supply single pieces, while others sell packs. Buyers should verify grommet durability and measure fitment before purchasing individual grommets.
Is Any Adhesive or Lubricant Included?
No; the product contains no adhesive or lubricant. The reviewer notes adhesive application is left to the installer, and suggests considering compatible lubricant options (silicone spray or rubber protectant) to ease installation and protect grommet material.
