Leather Seals Well Cup Packing

Many water pumps and Hydraulic units still use leather seals and Cup Seals. We are able to offer a service to make these items for you, to your required size.

Leather is tough, pliable, and wear resistant, unaffected by cold, enabling it to withstand high pressure at low temperature.
Leather seals, such as cups, flanges and u-packings take on the shape they need in order to seal. If you've got a little bit of wear, or you're a bit out of true, leather is going to fill the voids whereas the rubber or plastic cannot. They just are not flexible enough.

Leather was used for sealing before Elastomers.

The reason it is still being used today for presses, cylinders, valves, etc. is flexibility.

Leather has an extremely large sealing tolerance that conforms to and polishes the surface it is sealing.

Treated Leather can cater for a wide range of requirements.

Leather can replace seals no longer manufactured or replace current seals that are unattainable due to lead-time, expense, etc.
