China O Ring Mechanical Seals WM250

China O ring mechanical seals WM250 is made of high-quality materials by an advanced process with several patented technologies. They have very complicated shapes, high accuracy, stable mechanic properties, much higher wear and corrosion resistance, and service life of more than twenty thousand hours in the normal case.

Product Description

China O Ring Mechanical Seals WM250 are mechanical gaskets with a round cross-section. They are made from elastomer materials and used in pumps, cylinders, and other fluid applications to form a leak-proof seal between two parts. 

China O ring mechanical seals WM250 are installed into a machined or molded groove on a part surface. When the two parts are joined, it compresses the O-ring and deforms the cross-section, creating a tight seal. We have materials of Nitrile, Silicone, EPDM, FKM, Viton, FFKM, and HNBR. If you are unsure of which material is best for your application, view our Properties Comparison Chart for information about some of the most commonly used O-ring materials or contact us for assistance.
