Description
It’s made from Buna-N nitrile rubber. This is a trusted material that resists swelling and degradation from oils and greases. It’s a practical choice for most general sealing tasks in a pump environment.
Replacing a worn or flattened large O-ring can solve persistent leak issues. This Busch part guarantees the exact size and material quality for a perfect fit. Keep your large connections secure and leak-free.
