PTFE Rod & Piston seals
“QuanSeal” piston and rod seals are used in hydraulic and pneumatic systems.This seal is a combination of a PTFE slip ring and an energizing O-ring. It is produced with an interference fit, which together with the squeeze of O-ring ensures a good sealing effect even at low pressure. At higher system pressures, the O-ring is energized by fluid, pushing the slip ring against sealing face with increased force.
 
We produce a wide range of PTFE piston and rod rings for a variety of standard piston bore and rod dimensions.
