O Ring Mechanical Seals WM250

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. 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.

Product Description

The seal is designed to have a point of contact between the o ring mechanical seals and sealing faces. This allows high local stress, able to contain high pressure, without exceeding the yield stress of the O-ring body. The flexible nature of O Ring Mechanical Seals WM250 materials accommodates imperfections in the mounting parts. But it is still important to maintain the good surface finish of those mating parts, especially at low temperatures where the seal rubber reaches its glass transition temperature and becomes increasingly crystalline. Surface finish is also especially important in dynamic applications. A surface finish that is too rough will abrade the surface of the o ring mechanical seals, and a surface that is too smooth will not allow the seal to be adequately lubricated by a fluid film.
