Hydraulic Seals for Cylinder Ptfe Ring

The step seal for hole is composed of rubber O-ring and PTFE ring. The O-ring exerts force to seal the double-acting piston, low friction, no creep, low starting force, high pressure resistance; static sealing effect is equivalent Great.

Hydraulic Seal has a special flld PTFE ring with a pre-loaded lip energised by an 0 ring. The lip is designed to have a contact area with the rod adequate to retain the media at low pressure. As high pressure acts on the 0 ring it compresses the lip against the rod increasing the contact area and the effectiveness of the seal.

The PTFE ring should always be mounted with the sealing lip on the pressure side. A number of material options can be provided to extend operating conditions. Characteristics:

A PTFE step seal and an 0-ring used as an energizer can be used in high pressures up to 500bar and for reciprocating motion up to 15 m/s. Temperature range is -50° C to +200° C (depending on the components used for 0O-ring). Since the PTFE is flled with Bronze or Carbon, the abrasion resistance property is very high.
