Hydraulic Seals

CDK Seal specialise in the manufacture and supply of hydraulic seals.

Seal Kits for Hydraulic Cylinders

CDK offer a kitting service for hydraulic cylinder manufacturers and repairers. We spec the required seals and create seal kits to customers requirements. We hold stocks inorder to cut down breakdown times. We deal with all major seal manufacturers thus reducing the work load of already over stretched purchasing departments

Hydraulic applications are challenging for seals.

Not only must the hydraulic seals prevent leakage of fluid from the cylinder, but hydraulic seals must also withstand high pressures, extreme temperatures and transverse forces within the cylinder.

In such applications, the function of Hydraulic Seals goes far beyond preventing fluid leakage.

Piston Seals or Piston Rings are used in hydraulic cylinders for fluid sealing.

They are internal to the cylinder head and seal against the cylinder bore, preventing fluid from flowing across the cylinder head.

This allows pressure build up on one side of the piston, making the cylinder extend or retract.

Hydraulic Cylinder Seals

Hydraulic systems are sealed using a combination of specialized seals.

Rod seals prevent leakage of fluid from within the cylinder to the outside while hydraulic piston seals prevent fluid from flowing across the cylinder head.

This allows pressure build up on one side of the piston, making the cylinder extend or retract.

Wear rings guide the piston and piston rod within the hydraulic cylinder, absorbing transverse forces, preventing metal-to-metal contact.

Scrapers or wipers scrape dirt, foreign particles, chips or moisture from the piston rods as they retract into the cylinder.
