Parker PC504-BP Push-lok Hose Barb Straight Coupler Brass

Product Description

The PARKER PC504-BP is a Push-Lok hose barb straight coupler designed for use in fluid handling applications where a reliable, low-profile connection is required. Constructed from brass, this coupler features a non-threaded shaft with a threaded body connection and is rated for a maximum working pressure of 200 psi. It accepts 0.5-inch inside diameter hose and is built to handle temperatures ranging from -20 degrees F to 400 degrees F. The PC504-BP is part of Parker's Moldmate series, making it a recognized choice for professionals who need consistent, repeatable connections in demanding environments. Installation is handled by qualified fluid system or industrial maintenance technicians.

The PC504-BP is specifically suited for die casting equipment and mold coolant lines, which are the stated applications for the Moldmate series. Its straight coupler geometry and 0.5-inch hose ID sizing make it a straightforward drop-in for coolant circuit assemblies where space and orientation allow a direct inline connection. The brass construction offers solid corrosion resistance in the water-based coolant fluids common in these applications. This coupler ships individually and has a minimum order quantity of one unit.

Installation Notes

Installation should be performed by a qualified fluid systems technician or industrial maintenance professional. Before servicing any coolant line, relieve system pressure completely and allow fluid temperatures to drop to a safe handling level. Push-Lok style fittings require the hose to be pushed firmly onto the barb until fully seated — inspect the connection visually before returning the system to service. Follow applicable facility safety procedures and equipment manufacturer guidelines for pressure testing after assembly.
