NRW-Design Viton Florine Rubber BMW Oil Cap Gasket O-Ring

The NRW-Design Viton Oil Cap Gasket / O-Ring is a high-performance replacement for worn or leaking oil filler cap seals on BMW engines. Made from premium fluorine rubber (Viton®), this gasket is engineered to resist oil, fuel, and high engine bay temperatures far better than standard rubber O-rings.

Over time, OEM oil cap seals can shrink, crack, or harden—leading to oil seepage or contamination. NRW's Viton O-ring offers a long-lasting, leak-free seal and is compatible with a wide range of BMW engines across multiple chassis.
