Rubber washers for automotive systems need to stand up to oil, fuel, heat and constant vibration. We stock automotive-grade washers in every OD, ID and thickness, cut from materials chosen for fuel and oil resistance.
Best materials for automotive use
For fuel systems, hydraulic lines and engine components we recommend Nitrile, Viton and Neoprene. Nitrile is the workhorse for fuel and oil contact, Viton handles the highest temperatures and most aggressive chemicals, and Neoprene is a cost-effective all-rounder for weatherstripping and general sealing.
Common sizes
- 1/4" to 1" OD for fuel fittings
- 1/2" to 2" OD for engine mounts
Key properties to look for
- Oil and fuel resistance
