This matched coupling set includes the Parker Pioneer 4010-2P male tip and the 4050-2P female coupler from Parker's 4000-Series hydraulic quick-disconnect line. Built to the ISO 5675 agricultural standard, these components are widely used on tractors, implements and general mobile hydraulic equipment. The manual-connect sleeve and poppet-valve internals support controlled fluid passage during connection and disconnection, while the plated steel construction is suitable for demanding outdoor and agricultural environments. This pair provides compatibility with systems that use Pioneer-pattern 1/4-body agricultural couplers. Confirm thread type, body size and hydraulic requirements prior to installation.
