Rubber Piston Cup Seals

Back to hydraulic seals pneumatic seals.

Rubber piston cup seals.

These are designed for pneumatic or low pressure hydraulic applications. Homogeneous rubber is bonded to a metal disc only one part is required the most practical piston cup available. 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. 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. Mfp seals also produced a line of double acting piston cups pcd piston cups that replace multi part assemblies. They are usually specified in low speed low pressure environments for both pneumatic and hydraulic cylinders. Our product line includes.

They are developed to fit into standard o ring grooves. For example speed is affected by pressure temperature and other operating conditions. Piston cups can include a hole in the center of the cup. Our machining department is equipped to quickly cut the appropriate hole size for your application.

Type spring energized rod seal inside diameter decimal inch 0 7500 minimum temperature f 100 maximum temperature f 450 rod diameter decimal. T seals have solved some reliability issues including extrusion through the gap and spiral or twisting failure. Maximum performance values cannot be achieved simultaneously. Piston cups provide a mechanical sealing surface on the edge of hydraulic and pneumatic piston heads plungers and rams.

Buffering seals protect hydraulic cylinders from pressure spikes and shock in high pressure hydraulic applications. Piston seals make a seal between their outside edge and the cylinder bore to prevent internal leaks. Cushioning seals minimize wear and noise in air powered cylinders by preventing the piston from slamming against the cylinder body. These buna n seals are reinforced with cotton thread for strength.

Basic piston cup seals are typically used in low pressure pneumatic and hydraulic cylinders. To maximize product availability hi tech seals piston cups do not come with a pre cut bolt hole. Piston cups piston cup seals are used on rams or plungers in both hydraulic and pneumatic 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. Piston t seals and rod t seals are compact efficient seals that were originally designed as an effective replacement for o rings.
