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.
JST's back up ring compensate for large temperature fluctuations. Using Back-up Rings allows O-Rings to be utilized in higher pressure applications, where larger extrusion gaps are required and where there are reciprocating or rotating movements. Back-up Rings are protective and supporting elements with no sealing function. The back up ring material could be PEEK, modified PTFE.
VT type V Packing is widely used for sealing pistons and rods with both single and double acting cylinders.
JST's Packer elements are flexible elastomeric components that are used to seal between the outside diameter of the production tubing and the casing, liner or wellbore.
Dovetail groove is used to put the O-ring or elastomer dovetail seal during installation. This groove is not common because it is more expensive to machine, but this dovetail groove can avoid seal extrusion out.
Hammer union seals are used for hammer joint type pipe connections to establish flow lines and prevent leakage.
