JST seals produce high-quality throttle valve and gate valve equipment seals. Choke packing throttle valve are control valves for production wells, which are used to control the flow of well fluid under production. The throttle valve also compresses the pressure from the reservoir and regulates the downstream pressure in the flow line. Choke packing is available in a variety of types and material ...

Oil and Gas pumping equipment is the lifeline of hydraulic fracking and drilling operations. When pumps go down for planned or unplanned repairs, productivity comes to a halt. JST sealing profile can make the equipment run longer and more efficient. Well Service Packing（ plunger packing seal） was developed to eliminate extrusion and provide excellent abrasion resistance for fracturing, acidizing, ...

JST new design of Lockdown screw packing is made from one PTFE ring and two copper rings. PTFE ring is able to lower the holding force and friction, thus lower the torque. Meanwhile, two copper rings can better protect the LDS body not to be damaged during the twisting and rotating process. JST has conducted the test to qualify the PR2 performance of 1.51 inch LDS packing seal at L-X -46℃~177℃ ( -...

Lockdown Screw packing seal is usually made of an HBNR compression packing element with molded metal end caps. But JST has developed a lockdown screw packing seal which is made of one filled PTFE and two cooper end caps. It is the sealing between wellhead members in a wellhead, including a seal element and a lockdown member. The seal is attachable to either one of the wellhead members by coup...

A water pump seal is a mechanical component that helps to contain the liquid inside a pump and prevent it from leaking. The seal is usually located between the pump's rotating shaft and the pump housing. The purpose of a water pump seal is to provide a barrier between the liquid being pumped and the environment outside the pump, thus preventing leaks and contamination of the liquid. There are seve...
