Rapid Gas Decompression O ring

Wear rings are used to help keep the piston centered, allowing for even wear and pressure distribution on the seals. Wear rings are used in both piston and rod applications.

It is an end face spring energized seal with both rigid and flexible elements, which gives consistent contact at the sealing interface.

EVZ is commonly used in high-pressure mud pumps and fracturing pumps, namely Packings, the high-speed reciprocating dynamic seals.

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.

The ID S seal is used for wellheads, downhole tools and surface pressure control equipment as a critial part.

ptfe wear strips can keep the piston centered as well as preventing metal-to-metal contact.

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.

This is sealing product developed by JST to meet the increasingly demanding sealing needs of equipment manufacturers and users in semiconductor, petrochemical, mechanical seal, instrumentation, energy, biopharmaceutical, food and medical industries.
