Pacific Seals Catalogues Click on each catalogue to view and download. We have pain-stakingly crafted our range of O-Rings, Wipers and Piston seals into catalogues. Wiper Catalogue Hydraulic cylinders operate in a variety of applications and environmental conditions, including exposure to dust, debris or outside weather conditions.

To prevent these contaminants from entering the cylinder assembly and hydraulic system, wiper seals also known as scrapers, excluders or dust seals are fitted on the external side of the cylinder head. Wiper seals maintain sealing contact to the piston rod when the equipment is both stationary and in use. Thishelps to make sure foreign contaminants can not enter the cylinder when the piston is retracting.

Single Acting Piston Seals Catalogue Piston Seals or Piston Rings are used in hydraulic cylinders for fluid sealing and are designed to ensure that pressurised fluid does not leak across the cylinder head as the system pressure pushes the piston down the cylinder bore.

The choice of piston seal is decided by the way in which the cylinder operates. For a cylinder which is exclusively single-acting, capable of sealing dynamic pressure from one side unidirectional , it is always best to choose the type of seal designed to provide optimum sealing qualities for single-acting functions. Double Acting Piston Seals Catalogue Double acting cylinders are the most widely used cylinder types.

They operate via pressure acting on both sides of the piston, and therefore require double-acting seal arrangements. Double acting piston seals have a symmetrical profile and identical sealing functions in both directions. Typically, double-acting piston seals consist of a sealing ring and an energizer.

The deformation of the elastomeric energizer when installed provides adequate force to keep the sealing ring in dynamic sealing contact with the cylinder bore, while itself sealing statically against the seal housing groove. Imperial O-Ring Chart.
