Rubber Piston Cups

Nitrile fabric reinforced and urethane wear rings.

Rubber piston cups.

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. Dapc style double acting piston cups. Wear rings guide the rod and piston to prevent uneven wear and optimize seal performance. Moulded cups are a form of automatic packing which are popular as a piston seal for both single and double acting cylinders.

Find v rings u cups piston cups at msc industrial supply serving the metalworking safety and mro industries for over 75 years. Head seals are a more reliable alternative to the standard o ring backup ring combination they resist twisting. Piston cups piston cup seals are used on rams or plungers in both hydraulic and pneumatic applications. Ct style piston cups designed for low pressure applications that can withstand pressure up to 150 psi temperatures from 40 f to 220 f and speeds of 3 ft second.

Piston cups seal on their outer lip and are held in place by a follower plate. Piston cups are primarily used on piston heads rams and plungers in pneumatic or hydraulic service. High pressure leather u cup seals rated for pressure up to 10 000 psi these leather u cups handle over 80 times more pressure than our buna n u cups. To obtain the best results from any style of piston cup it is recommended that the piston properly support the heel of the cup.

Also known as lip seals u cups have a sealing lip on both the inside and outside edges so they can be used for rod and piston sealing. Our machining department is equipped to quickly cut the appropriate hole size for your application. Standard fabric rubber cups are available in 500 700 and 800 series. Hi tech seals also stocks edbro and renn piston cups in unique sizes.

These are designed for pneumatic or low pressure hydraulic applications. Wear rings have high compressive strength and load bearing capabilities. To maximize product availability hi tech seals piston cups do not come with a pre cut bolt hole. They are capable of withstanding relatively high pressures and shock loads.

Rod seals maintain the pressure inside cylinders and prevent fluid from leaking out. Homogeneous rubber is bonded to a metal disc only one part is required the most practical piston cup available. Piston cups can be furnished with or without center holes. Housings are usually quite simple which makes them economical to install.
