Single-acting Piston seals

Single Acting Piston Seals of all types and materials, in all sizes.

The function of a piston 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. Single Acting pistons only contain pressure on one side of the piston, and the seal is required to contain pressure from that direction, which then moves the piston along the cylinder, in a "Single Action". The return stroke of the cylinder must be powered by mechanical energisation or possibly a simple gravity return. 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.
