Hydraulic PTFE rotary seals

High-pressure Rotary shaft seals are one bidirectional rotary seal which can bear both sides of pressure and alternating pressure. It is made with slip ring and o-ring/square ring.

Rotary shaft seals with PTFE ring have been specially developed for use in harsh conditions. They are used when shaft seals with classic elastomer lips reach their performance limits.

PDR rotary shaft seal extends the boundaries of elastomeric radial shaft seals, utilizing advanced materials and design techniques to provide optimal sealing performance for each application. The result is a superior sealing solution that retains a compact sealed casing.

Outer wireline valve seals are used in various type of Blow Out Preventors (BOP's).

Pack off seal or Secondary Seal Assemblies is installed in the lower seal area of the Casing Spool or Tubing Head.

Back-up Ring/Anti Extrusion Rings is a ring that holds an elastomeric seal to its outline shape and in its right place. and are typically used with O Rings to eliminate extrusion at high pressures.

Piston seals are working to seal in fluid, thus preventing the flow of fluid across the piston, allowing pressure to build up on one side of the piston.

The function of a hydraulic wear ring is to guide the piston and piston rod of a hydraulic cylinder, absorbing transverse forces. At the same time, it prevents metal-to-metal contact, optimizing the performance of the sealing system.
