This matched coupling set includes the Parker Pioneer 4010-3P male tip and 4050-3P female coupler, both part of the 4000-Series hydraulic quick-disconnect line built to ISO 5675 agricultural-style specifications. Designed for common tractor, implement and mobile-equipment hydraulic ports, the manual-connect sleeve and poppet-valve design support controlled fluid passage during connection and disconnection. Constructed from plated steel for durability, this pair provides compatibility with systems that use Pioneer-pattern quick couplers in this body size. Suitable for agricultural attachments, loader implements and general mobile hydraulic service. Confirm thread type, body size and system pressure requirements prior to installation.
