PTFE Seals-type RA
PTFE Glide seal sets are mainly used to seal reciprocating rods, pistons and plungers.
The types R1, R2, RL, P1, P2, and PD are mainly used in hydraulic applications. They have proven their excellent performance in, for example, machine tools, molding machines, control devices, construction equipment and vehicles. The PP profile is specially designed for use in pneumatic applications. If a seal set is to be used as end seal, we recommend a wiper also be adopted. The profiles come in various material combinations to meet the requirements of the particular application.
Rod seal is suitable for bi-directional pressurization, hydraulic cartridge and spool valves such as control cylinders, servo-controlled systems, machine tools, and construction machinery. It offers low break-out and running friction to guarantee steady movement even at low speed or intermittent but frequent reciprocating action.
