CSTobturating ring assembly

CSTobturating ring assembly

CST combination seal is a kind of widely used in high pressure overload in the cases of double piston sealing ring. It has the good ability of containment, extrusion and wear resistance. CST combination sealing ring is especially in the case of long stroke. And in a wide range of flow and high temperature, can adapt to the larger piston gap. CST combination seal after stacking manner to form a compact structure, good performance, and can be installed inside a single piston groove. Its geometry has the overall stability, abrasion resistance, sealing, low friction and long life without maintenance. By setting the initial interference, so the sealing ring has good sealing performance at low pressure. When the pressure, sealed performance is very good also, because of the elastomer applying pressure to the combination sealing ring, the axial force produced by the system pressure into radial extrusion. Apply to the overloaded nylon collar, is specially designed to protect seals from extrusion, meet all kinds of hydraulic cylinder applications.
