Imperial O-Rings – 2-Series (AS568) + Backups

Forge Industrial Supplies supplies a full range of 2-Series (AS568) imperial O-rings for hydraulic, pneumatic, and industrial sealing applications. The 2-Series inch range is widely used across hydraulic cylinders, pumps, motors, valves, and OEM-equivalent equipment.

Imperial O-rings are available in NBR70, NBR90, and FKM compounds. For higher-pressure applications and larger extrusion gaps, NBR backup rings are available to support the primary seal and improve service life.
