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.

Rubber piston cup seals.

Piston cups can include a hole in the center of the cup. Basic piston cup seals are typically used in low pressure pneumatic and hydraulic cylinders. These buna n seals are reinforced with cotton thread for strength. Buffering seals protect hydraulic cylinders from pressure spikes and shock in high pressure hydraulic applications.

They are usually specified in low speed low pressure environments for both pneumatic and hydraulic cylinders. These are designed for pneumatic or low pressure hydraulic applications. Piston t seals and rod t seals are compact efficient seals that were originally designed as an effective replacement for o rings. Usa sealing 3 4 id spring.

To obtain the best results from any style of piston cup it is recommended that the piston properly support the heel of the cup. T seals have solved some reliability issues including extrusion through the gap and spiral or twisting failure. Piston cups seal on their outer lip and are held in place by a follower plate. Universal rod piston u cups symmetrical u cups are popular due to the small gland space required.

Hi tech seals also stocks edbro and renn piston cups in unique sizes. Back to hydraulic seals pneumatic seals. Maximum performance values cannot be achieved simultaneously. 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.

Type spring energized rod seal inside diameter decimal inch 0 7500 minimum temperature f 100 maximum temperature f 450 rod diameter decimal. Our product line includes. Piston seals make a seal between their outside edge and the cylinder bore to prevent internal leaks. Piston cups provide a mechanical sealing surface on the edge of hydraulic and pneumatic piston heads plungers and rams.

For example speed is affected by pressure temperature and other operating conditions. 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. Piston cups piston cup seals are used on rams or plungers in both hydraulic and pneumatic applications.

Cushioning seals minimize wear and noise in air powered cylinders by preventing the piston from slamming against the cylinder body. To maximize product availability hi tech seals piston cups do not come with a pre cut bolt hole.
