Ultra-Chemical-Resistant Rigid PTFE O-Rings
for High-Polish Metal Sanitary Tube Fittings

Pair these O-rings with metric sanitary fittings, which are commonly known as aseptic fittings. Made of PTFE, they’re rigid with a slippery surface and resist harsh chemicals such as acetone, fluorinated solvents, methanol, and boric acid. They’re 3-A certified to meet sanitary design standards. They have a round profile and are good for a wide range of static and dynamic sealing applications.
