Rubber Piston Cup Seals

Maximum performance values cannot be achieved simultaneously.

Rubber piston cup seals.

Piston cups piston cup seals are used on rams or plungers in both hydraulic and pneumatic applications. Piston t seals and rod t seals are compact efficient seals that were originally designed as an effective replacement for o rings. 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.

Hi tech seals also stocks edbro and renn piston cups in unique sizes. 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. Universal rod piston u cups symmetrical u cups are popular due to the small gland space required.

Piston cups provide a mechanical sealing surface on the edge of hydraulic and pneumatic piston heads plungers and rams. Piston cups can include a hole in the center of the cup. Usa sealing 3 4 id spring. Basic piston cup seals are typically used in low pressure pneumatic and hydraulic cylinders.

Our product line includes. Homogeneous rubber is bonded to a metal disc only one part is required the most practical piston cup available. 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. 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. These buna n seals are reinforced with cotton thread for strength. 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.

Piston seals make a seal between their outside edge and the cylinder bore to prevent internal leaks. These are designed for pneumatic or low pressure hydraulic applications. Our machining department is equipped to quickly cut the appropriate hole size for your application. They are developed to fit into standard o ring grooves.

Mfp seals also produced a line of double acting piston cups pcd piston cups that replace multi part assemblies. For example speed is affected by pressure temperature and other operating conditions.
