Hat or Cup Seals

Hat or Cup Seals of all types and materials, in all sizes.

The function of a hat or cup seal is to contain pressure on one side of a piston without leakage and therefore allow maximum effort to be applied to moving the piston along the bore of a cylinder. They are one of the oldest designs of seal, and can still be supplied in leather if required. Consideration needs to be given to the pressures expected, the friction losses acceptable, whether a single acting capability is required, and whether the piston head is integral or split.
