Frequently asked questions
Are these O-rings compatible with chemical cleaners?
NBR (nitrile) offers good resistance to water and many common cleaners and light oils, but it is not recommended for prolonged contact with some aggressive solvents. Test before use when in doubt.
Can I use these for garden hose fittings?
These O-rings are sized and intended for quick-connect pressure washer fittings. They may not fit standard garden hose threads; measure carefully before attempting to use.
