Rubber Piston Cup Seals

Our machining department is equipped to quickly cut the appropriate hole size for your application.

Rubber piston cup seals.

Piston cups seal on their outer lip and are held in place by a follower plate. Piston cups piston cup seals are used on rams or plungers in both hydraulic and pneumatic applications. Type spring energized rod seal inside diameter decimal inch 0 7500 minimum temperature f 100 maximum temperature f 450 rod diameter decimal. Usa sealing 3 4 id spring.

For example speed is affected by pressure temperature and other operating conditions. Back to hydraulic seals pneumatic seals. Cushioning seals minimize wear and noise in air powered cylinders by preventing the piston from slamming against the cylinder body. 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. Basic piston cup seals are typically used in low pressure pneumatic and hydraulic cylinders. Our product line includes. They are usually specified in low speed low pressure environments for both pneumatic and hydraulic cylinders.

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. T seals have solved some reliability issues including extrusion through the gap and spiral or twisting failure. Piston cups can include a hole in the center of the cup. Buffering seals protect hydraulic cylinders from pressure spikes and shock in high pressure hydraulic applications.

Hi tech seals also stocks edbro and renn piston cups in unique sizes. These buna n seals are reinforced with cotton thread for strength. Piston cups provide a mechanical sealing surface on the edge of hydraulic and pneumatic piston heads plungers and rams. Universal rod piston u cups symmetrical u cups are popular due to the small gland space required.

To maximize product availability hi tech seals piston cups do not come with a pre cut bolt hole. Piston seals make a seal between their outside edge and the cylinder bore to prevent internal leaks. They are developed to fit into standard o ring grooves. 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. To obtain the best results from any style of piston cup it is recommended that the piston properly support the heel of the cup.
