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.
Liner Wiper Plugs separates drilling fluid from cement during displacement.
SPGO is a low friction piston seal consisting of PTFE+Bronze seal ring and rubber o-ring used for two-way piston seal of Hydraulic cylinder, 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 JST valve insert seal is mainly used for sealing valve seat of fracturing pump. It is made of modified polyurethane material of excellent extrusion resistance, puncture resistance and fatigue resistance, which guarantees the fracturing work under various working conditions.
KZT is used in combination with anti-wear and piston ring to prevent cylinder oil from mixing with foreign particles, avoiding seal damage.
ODU Piston seals are work to seal in fluid, thus preventing the flow of fluid across the piston, allowing pressure to build up on one side of the piston.
