As we know FKM is fluororubber, also known as Viton. A kind of highly fluorinated polymers that are suitable for continuous use at elevated temperatures. So what FFKM means? Obviously, FKM and FFKM have some relationship, also share many similarities. But What does that extra F mean? JST seals are here to tell you what is FFKM. FFKM, or perfluoroelastomer, It’s a kind of sealing material whatever ...

PEEK is one of the most radiation resistant plastics in common use. It can withstand exposure of 109 rad before any performance degradation occurs. PEEK can also operate successfully at temperatures up to 500 ° F. PEEK is usually used for back-up rings, bearings, and structural seal components such as seal carriers and valve blocks. It's a challenge to create a spring energized seal jacket out of ...

A wiper plug typically has an elastomeric body mounted on a mandrel and elastomeric external fins that bear against the inner wall of the casing. The fins wipe mud solids and other accumulated debris off the inner wall of the casing. The effectiveness of a wiper plug relies on at least one fin creating a seal against the surrounding casing or liner, and the body sealing against the mandrel. The el...

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, ...

The downhole tool sliding sleeve seal, we usually call it sliding sleeve or V stack, is a two-way elastic energy storage combination seal. It is a commonly used sealing element in downhole tools for oil production. When the sliding sleeve is pushed to the proper position, the sliding sleeve   activates the sealing function to seal off the upstream, so that the fracturing work can be carried o...

According to different materials, hydraulic rotary seals must have the following performance characteristics: 1. The seals has certain mechanical and physical properties: such as tensile strength, constant elongation strength, and elongation; 2. The material structure of the seals has a certain degree of elasticity, the hardness is verified, and the compression permanent deformation is small; 3.3....
