Hallite® piston seals

Hallite® piston seals

Piston seals are used in hydraulic cylinders and are designed to ensure that pressurised fluid does not leak across the cylinder head when system pressure pushes the piston into the cylinder bore. The choice of piston seal is determined by the way the cylinder operates.

Hallite® single-acting piston seals

For a cylinder that is single-acting only and can seal dynamic pressure on one side, it is always best to choose the type of seal for single-acting functions.

Hallite® double-acting piston seals

The best sealing capacity of a double-acting cylinder that can seal dynamic pressure on both sides is achieved by choosing a double-acting seal. A piston design that uses two single-acting seals on the piston for a double-acting cylinder can easily cause failure, as very high pressure can build up between the seals.

Piston seals, both single- and double-acting, can be designed for and used with integrated or separate support rings and guide rings. Hallite offers a wide range of piston seals that provide the ultimate in leakage control. Piston seals are typically manufactured from our high-performance polyurethane Hythane® 181, Hallprene® rubber/tissue composite or polyester elastomer.
