55-58 Shore D PTFE Boss O-Rings are designed for SAE straight-thread O-ring Boss (ORB) fittings. Made from PTFE, they provide excellent resistance to high heat and harsh chemicals, including acetone, fluorinated solvents, methanol, and boric acid. Their low coefficient of friction supports durability and reliable sealing performance, while the inert PTFE material makes them primarily suited for static applications. Bulk discounts are available for large quantity purchases.
