  • Buna-nitrile is vulnerable to acetone, ethers, esters, ozone, sunlight, and weathering and should therefore not be used in ozone-generating electric motors, welding equipment, or in applications with exposure to UV light.

After measuring everything, this was the perfect fit for the 5 gallon easy pour Sceptor gas can. The O-rings dry out. This was the perfect replacement.

Needed these o rings to finish sealing up an airgun. Couldn’t find it anywhere else without having to order a bunch of orings and pay shipping. These were a great price and free shipping. Perfect fit too.
