Hydraulic Wedge Coupler

Series II Hydraulic Wedge Coupler
A PSM Series II Hydraulic Wedge Coupler gives you all of the versatility you need to change between attachments without losing any breakout force. This coupler provides an exceptional coupler-attachment fit because of our unique "wear compensating system." With this design, the spring-loaded hydraulic release system continually tightens the coupler. This process allows the operator to easily and quickly interchange attachments without ever leaving their cab. Attachments with the Series II coupler system may be interchangeable between various makes and models of excavators of the same class.
