S Seals is made from elastomer and two metal garter spring. The metal garter spring is incorporated into the elastomeric seal element. The one-piece S seal eliminates the installation issues that may occur when using multi-component seals. It can be stretched into place without splitting or damaging the non-extrusion components. S seal can be manufactured to accommodate almost any gland size, incl...

There are many factors that can cause RGD damage. It mainly includes the following aspects: Type of gas All types of gases can cause RGD damage, but H2S and CO2 have high permeation rates, so the effects of RGD can be particularly problematic. Due to aggressive carbon dioxide and hydrogen sulfide gas, rapid gas decompression (RGD) leads to degradation and collapse of polymer components, while putt...
