Viton® (FKM) 90 Duro SAE Boss O-Rings | Hydraulic ORB Seals

Viton® (FKM) O-Rings for SAE Boss hydraulic sealing are built for customers who need reliable performance in high temperature, high pressure, and aggressive chemical environments. These O-Rings are commonly used in SAE J1926 O-Ring Boss (ORB) fittings where leak prevention and long-term durability are critical. FKM material offers excellent resistance to petroleum oils, fuels, hydraulic fluids, and many chemicals, along with temperature capability up to 400°F. For our customers, this means fewer failures, longer service intervals, and more confidence in demanding applications like hydraulics, heavy equipment, and industrial systems. We stock a wide range of standard SAE Boss sizes with consistent quality, traceability, and fast shipping, so you can get the right O-Ring quickly without second guessing fit or performance.
