Rubber Piston Cup Seals

Cushioning seals minimize wear and noise in air powered cylinders by preventing the piston from slamming against the cylinder body.

Rubber piston cup seals.

T seals have solved some reliability issues including extrusion through the gap and spiral or twisting failure. These are designed for pneumatic or low pressure hydraulic applications. Mfp seals also produced a line of double acting piston cups pcd piston cups that replace multi part assemblies. Piston t seals and rod t seals are compact efficient seals that were originally designed as an effective replacement for o rings.

Our machining department is equipped to quickly cut the appropriate hole size for your application. These buna n seals are reinforced with cotton thread for strength. Maximum performance values cannot be achieved simultaneously. Piston cups can include a hole in the center of the cup.

To obtain the best results from any style of piston cup it is recommended that the piston properly support the heel of the cup. They are usually specified in low speed low pressure environments for both pneumatic and hydraulic cylinders. Back to hydraulic seals pneumatic seals. Piston cups provide a mechanical sealing surface on the edge of hydraulic and pneumatic piston heads plungers and rams.

Piston cups piston cup seals are used on rams or plungers in both hydraulic and pneumatic applications. Basic piston cup seals are typically used in low pressure pneumatic and hydraulic cylinders. For example speed is affected by pressure temperature and other operating conditions. Piston seals make a seal between their outside edge and the cylinder bore to prevent internal leaks.

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. Homogeneous rubber is bonded to a metal disc only one part is required the most practical piston cup available. To maximize product availability hi tech seals piston cups do not come with a pre cut bolt hole. Piston cups seal on their outer lip and are held in place by a follower plate.

The seal is obtained by means of the flared flexible lips coming in contact with the rod or cylinder wall. They are developed to fit into standard o ring grooves. 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. Our product line includes.

Hi tech seals also stocks edbro and renn piston cups in unique sizes. Buffering seals protect hydraulic cylinders from pressure spikes and shock in high pressure hydraulic applications.
