Metal End Cap Seals are one of the metal bonded elastomeric seals with the high level of extrusion resistance necessary for high pressure casing and tubing applications. JST has designed a PEEK End Cap Seals instead of Metal End Cap Seals to meet with customers special requirement. Why do we choose a non-metallic non-extrusion device as non-extrusion device for this seal? It’s because the lock dow...

Stainless steel metal end caps provide an anti-extrusion mechanism and encapsulate the seal for protection. Because it contains a radially squeezed pressure energised rubber core, it can tolerate surface imperfections and mechanical damage on the wellhead bore. Special features Metal end caps are chemically bonded to element of high performance elastomer. Elastomer energises the system f...

With the development of sealing technology for high pressure environment, the requirements for sealing performance are more and more stringent. The high pressure sealing technology is widely used in EOG, chemical industry, aerospace and other fields. MEC seal is a non-metal sealing ring which is used under high pressure, with good corrosion resistance, high pressure resistance and resistance to ex...

JST’s metal end cap seal is a customized elastomer-to-metal seal that combines the advantages of metal-on-metal components with the flexibility of elastomeric seals for maximum extrusion resistance in high-pressure wellhead sealing environments. These high performance elastomer-to-metal bonded sealing elements provide the high level of extrusion resistance necessary for high pressure casing and tu...

MEC seal is short for Metal End Cap Seal, and it is the seal bonded the metal end cups on elastomer, which can provide a high level of extrusion resistance and metal to metal sealing. MEC seal is designed for EOG applications in harsh conditions, particularly for high pressures and high temperatures. Usually the elastomer can be HNBR, FKM, Aflas which depends on the application, and the material o...
