Resist leaks better than metal sealing washers, but are more susceptible to wear and tear. Reuse these washers a handful of times, as long as the material isn't damaged.
Oil-Resistant Aramid-Reinforced Buna-N—These washers are embedded with aramid, which is the same material used in bulletproof vests. This addition makes them stronger and more heat resistant than standard Buna-N washers for a longer lifespan. They won't degrade when exposed to oil, grease, and fuel.
