Rubber Piston Cup Seals

T seals have solved some reliability issues including extrusion through the gap and spiral or twisting failure.

Rubber piston cup seals. 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. Universal rod piston u cups symmetrical u cups are popular due to the small gland space required. Piston t seals and rod t seals are compact efficient seals that were originally designed as an effective replacement for o rings. For example speed is affected by pressure temperature and other operating conditions.

To obtain the best results from any style of piston cup it is recommended that the piston properly support the heel of the cup. Buffering seals protect hydraulic cylinders from pressure spikes and shock in high pressure hydraulic applications. Our machining department is equipped to quickly cut the appropriate hole size for your application. 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. Back to hydraulic seals pneumatic seals. Basic piston cup seals are typically used in low pressure pneumatic and hydraulic cylinders. Usa sealing 3 4 id spring.

The seal is obtained by means of the flared flexible lips coming in contact with the rod or cylinder wall. Mfp seals also produced a line of double acting piston cups pcd piston cups that replace multi part assemblies. These buna n seals are reinforced with cotton thread for strength. Cushioning seals minimize wear and noise in air powered cylinders by preventing the piston from slamming against the cylinder body.

Maximum performance values cannot be achieved simultaneously. Piston seals make a seal between their outside edge and the cylinder bore to prevent internal leaks. Homogeneous rubber is bonded to a metal disc only one part is required the most practical piston cup available. They are developed to fit into standard o ring grooves.

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. Hi tech seals also stocks edbro and renn piston cups in unique sizes. These are designed for pneumatic or low pressure hydraulic applications. Piston cups seal on their outer lip and are held in place by a follower plate.

Our product line includes. To maximize product availability hi tech seals piston cups do not come with a pre cut bolt hole.
