* Forged & World Top Class Heat Treated Piston Hub,
AISI 5140/4140/4135 (40Cr/42CrMo/35CrMo)
(Or customized material)
* Flex Lip Type, Dual Durometer Polyurethane Technology:
The harder lower part polyurethane provides a better adhesion and support to piston hub while the softer upper part polyurethane provides a more flexible and better sealing performance to liner. The Dual Durometer Polyurethane Technology realizes a perfect combination of polyurethane to enhance the extrusion & abrasion resistance, as well as high pressure resistance performance of the piston polyurethane and therefore leads to better sealing effect and longer service life in high pressure applications.
* Bonded Piston Type Benefits:
1)Increased structural strength with very high tensile strength for longer operation life,
2)Improved shock absorption and minimized shock when piston moves,
3)Enhanced sealing capabilities and sealing failure prevention via Reduced possibility for fluids to penetrate between the polyurethane insert and the piston hub
