Rubber Piston Cup Seals

Back to hydraulic seals pneumatic seals.

Rubber piston cup seals.

Piston cups piston cup seals are used on rams or plungers in both hydraulic and pneumatic applications. They are usually specified in low speed low pressure environments for both pneumatic and hydraulic cylinders. Piston cups provide a mechanical sealing surface on the edge of hydraulic and pneumatic piston heads plungers and rams. Maximum performance values cannot be achieved simultaneously.

Our machining department is equipped to quickly cut the appropriate hole size for your application. Mfp seals also produced a line of double acting piston cups pcd piston cups that replace multi part assemblies. For example speed is affected by pressure temperature and other operating conditions. Usa sealing 3 4 id spring.

Cs style piston cups that can withstand pressure up to 2 500 psi temperatures from 35 f to 220 f and speeds of 1 5 ft second. Buffering seals protect hydraulic cylinders from pressure spikes and shock in high pressure hydraulic applications. All seals is a world leader in supply of high quality o rings seals engineered rubber and plastic products which serves the sealing needs of clients since 1958. To maximize product availability hi tech seals piston cups do not come with a pre cut bolt hole.

Homogeneous rubber is bonded to a metal disc only one part is required the most practical piston cup available. Piston seals make a seal between their outside edge and the cylinder bore to prevent internal leaks. The seal is obtained by means of the flared flexible lips coming in contact with the rod or cylinder wall. T seals have solved some reliability issues including extrusion through the gap and spiral or twisting failure.

Cushioning seals minimize wear and noise in air powered cylinders by preventing the piston from slamming against the cylinder body. Our product line includes. Type spring energized rod seal inside diameter decimal inch 0 7500 minimum temperature f 100 maximum temperature f 450 rod diameter decimal. These buna n seals are reinforced with cotton thread for strength.

Piston t seals and rod t seals are compact efficient seals that were originally designed as an effective replacement for o rings. These are designed for pneumatic or low pressure hydraulic applications. Universal rod piston u cups symmetrical u cups are popular due to the small gland space required. To obtain the best results from any style of piston cup it is recommended that the piston properly support the heel of the cup.

Hi tech seals also stocks edbro and renn piston cups in unique sizes. Piston cups can include a hole in the center of the cup.
