High-Pressure Ultra-Chemical-Resistant PTFE Backup Rings


O-Ring Deforms Without a Backup Ring	O-Ring Sealing Properly with Backup Ring

Protect O-rings in equipment operating at pressures up to 4,300 psi. These backup rings support O-rings to extend their life and prevent them from deforming under pressure, which can cause pressure loss. Made of PTFE, they’re rigid enough to hold their shape under load, yet slippery enough to reduce friction in moving parts. They also resist a wide range of chemicals. Often used in pipeline valves and chemical processing equipment, they have a split ring design to simplify installation. All have a shelf life, cure date, and a traceable lot number printed on the bag.

High-Pressure Hydraulic Cylinder Buffering Seals


Side 1	Side 2	Profile

Rated for pressure up to 10,000 psi, these seals withstand the highest pressure of our buffering seals. Use in tandem with rod seals to protect the cylinder from pressure spikes and shock.

Note: Maximum performance values cannot be achieved simultaneously; for example, speed is affected by pressure, temperature, and other operating conditions.

High-Pressure Piston Seals


	Profile

Rated for pressure up to 10,000 psi, these seals withstand the highest pressure of our piston seals. They have two high-strength backup rings that protect against extrusion.

Note: Maximum performance values cannot be achieved simultaneously; for example, speed is affected by pressure, temperature, and other operating conditions.
