50High pressure rotary lip seals
High Pressure Rotary Seals is one bidirectional rotary seal which can bear both sides of pressure and alternating pressure. high pressure hydraulic seals is made with slip ring and o-ring/square ring.
It adopts a toothed section, which is easier to install. The two grooves are the same and interchangeable. They are used to seal the rod, shaft, pin and rotary joint with high-speed rotation or swing movement. They have the characteristics of high pressure resistance, wear resistance, high temperature resistance, resistance to most chemicals.

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.
High pressure Rotary Seals is one bidirectional rotary seal which can bear both sides of pressure and alternating pressure.
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.
XTP is Double acting piston seals, composed of PTFE piston sealing ring, O-ring and X ring, and is used for the piston bidirectional seal of hydraulic cylinder. Especially suitable for separating two different mediums.
The V Stack seal assembly is comprising a top adapter or anti-extrusion ring (1), Vee Rings (2) and a bottom adapter (3). In the assembly the energizing axial force is transferred between the individual packing rings so that each ring is pressed into positive contact with the mating hardware surface. Special material grades are available for a large variety of working conditions. The chevron seal stack material could be PEEK, modified PTFE and spring.
Lockdown screw seal is used mainly in geothermal applications, HNBR packing with stainless steel caps provide superior performance over metal pressure seals.
S-Seal is designed for extreme oil and gas applications. It is a technologically advanced replacement for traditional three-piece T-Seals or O-Rings with back-ups.
A glass filled nylon wear ring, also called wear band, offers high bearing load capacity over a broad range of temperatures.
