U41
Type U41 has symmetrical sealing elements which are self energizing and activated by unit pressure.
Application: Hydraulic Reciprocating actions under Extreme Pressures.
Function: All three types are single function piston/rod seals.
Material: Polyurethane 90sh (Blue)

U43
Type U43 has asymmetrical sealing elements with a slightly shorter outer sealing lip. The energy is forced outward to strengthen its sealing function at low to extreme pressures.
Application: Hydraulic Reciprocating actions under Extreme Pressures.
Function: All three types are single function piston/rod seals.
Material: Polyurethane 90sh (Blue)

U45
Type U45 has asymmetrical sealing elements with a slightly shorter inner sealing lip. The energy is forced inward to strengthen its sealing function at low to extreme pressures.
Application: Hydraulic Reciprocating actions under Extreme Pressures.
Function: All three types are single function piston/rod seals.
Material: Polyurethane 90sh (Blue)
