Polypac

Polypac Sealing stems is the registered trademark with which since 30 years are identified hydraulic seals produced and distributed worldwide. The availibility of a complete range of competitive and innovative solutions comes from a close co-operations with main oleodynamics machines and systems OEMs, who are the principal objects of attention and support.


The resulting materials choice, the accurate shape study, and exhaustive lab tests on samples and applications, satisfy the ever growing performance requirements, minimising production costs. Quality and Competitiveness are the targets of polypac's action. The continous improvement of control systems on process and products is pursued, in order to reach the goal of "Zero Defects".

Polypac designs, develops, and manufactures a wide range of seal profiles from many types of materials including Nitrile (NBR), Fluoro Elstomer (FKM), Ethylene Propylene (EPDM), Polyurethane (PU), Polyester Resin (UP), Acetal Resin (POM), and Poly-Tetra-Fluoro-Ethylene (P.T.F.E.). polypac sealing systems offer the following:

  • wide range of seal types and materials.
  • pressure energising to ensure that maximum safety and efficiency are ensured.
  • special technical solutions to withstand the mose severe stresses for extended periods.
  • special materials designed to achieve and maintain the properties necessary for the seal to function correctly.
  • reduced cost resulting from modern production methods.

Polypac also provides a range of complementary to the seals, such as Guide Rings and Wipers, so as to offer the complete Sealing System.
