Parker 4050-15P O-ring Boss Poppet Coupler 1/2 in 3000 Psi

Product Description

The PARKER 4050-15P is a straight, threaded O-Ring Boss poppet coupler designed for hydraulic hose assemblies operating at pressures up to 3,000 psi. Built from steel with a 1/2 inch body diameter and 3/4-16 thread size, this coupler provides a leak-resistant connection in demanding hydraulic circuits. It is rated for a maximum flow rate of 12.00 GPM and meets ISO 5675 standards. Licensed HVAC and fluid-power technicians, hydraulic equipment mechanics, and industrial service professionals install this fitting in systems where reliable quick-connect performance is required under sustained working pressure.

This coupler is suited for use in add-on hydraulic circuits, hydraulic loaders, and hydraulic tool applications. Its straight configuration and threaded SAE connection type make it a direct-fit component in mobile equipment, skid-steer attachments, and tool-circuit plumbing where a compact, low-profile coupler body is necessary. The 4000 Series design supports consistent performance across a range of hydraulic tooling and loader installations common in agricultural, construction, and industrial service environments.
