Parker PC504 Hose Barb Straight Coupler 0.5 in 200 Psi

Product Description

The PARKER PC504 is a brass hose barb straight coupler designed for fluid conveyance in industrial and manufacturing environments. Part of the Moldmate series, this non-valved fitting accepts a 0.5 inch inside diameter hose and handles a maximum working pressure of 200 psi. It operates across a wide temperature range, from -20 degrees F to 400 degrees F, making it suitable for demanding process conditions. The straight body profile and threaded connection type allow for straightforward inline installation. Hydraulic and process piping technicians typically install this fitting in controlled fluid systems where a reliable, leak-resistant barb connection is required.

The PC504 is specified for use with die casting equipment and mold coolant lines, which are the primary applications called out in the Moldmate series. The 0.5 inch body diameter and non-threaded shaft make it compatible with standard hose barb assembly practices used in these process cooling circuits. It is equally applicable in other low-to-moderate pressure fluid systems where brass construction and a straight coupler geometry are appropriate for the service conditions.

Key Features

• Straight hose barb coupler geometry for inline fluid connections
• 200 psi maximum working pressure rating
• Brass construction for corrosion resistance in coolant and hydraulic media
• Wide service temperature range: -20 degrees F to 400 degrees F
• Non-valved design allows unrestricted flow when connected
• Part of the Moldmate series, engineered for die casting and mold cooling applications

Compatibility

Designed for use with die casting equipment and mold coolant lines as part of the PARKER Moldmate series. Fits 0.5 inch inside diameter hose assemblies with threaded connection interfaces.

Installation Notes

Installation should be performed by a qualified hydraulic or industrial piping technician. Depressurize and drain the system completely before removing or installing any fittings. Ensure hose ID matches the 0.5 inch barb specification and that clamp or crimp terminations meet the pressure rating of the circuit. Follow applicable industrial fluid power standards and facility safety procedures during assembly.
