Parker PC306-BP Push-lok Hose Barb Straight Coupler Brass

Product Description

The PARKER PC306-BP is a brass Push-Lok hose barb straight coupler designed for use in fluid transfer and cooling applications. Rated to 200 psi maximum working pressure, this non-valved coupler features a 0.375-inch (3/8 inch) hose inside diameter and a 3/8-inch body diameter. It connects via threaded fittings on the mating end and uses a push-on barb attachment at the hose end, eliminating the need for clamps in compatible Push-Lok hose assemblies. Part of the Parker Moldmate series, it operates across a temperature range of -20 degrees F to 400 degrees F. Installation is performed by plumbers, pipefitters, or maintenance technicians working on industrial fluid systems.

The PC306-BP is intended for industrial and manufacturing environments where reliable low-to-medium pressure fluid connections are required. It is specifically suited for die casting equipment and mold coolant lines, where consistent flow and secure barb connections reduce leak points in coolant circuits. The Moldmate series designation indicates compatibility with Parker coolant line system components designed for mold temperature control applications.

Key Features

• 200 psi maximum working pressure for low-to-medium pressure coolant and fluid lines
• Brass construction provides corrosion resistance in water-based coolant service
• Push-Lok hose barb design allows tool-free hose attachment without separate clamps
• Non-valved straight coupler — flow is unrestricted when connected
• Operating temperature range of -20 degrees F to 400 degrees F suits industrial thermal cycling environments
• Part of the Parker Moldmate series for die casting and mold coolant line assemblies

Compatibility

Designed for use with die casting equipment and mold coolant lines as part of the Parker Moldmate series. Verify hose inside diameter of 0.375 inches and system pressure do not exceed 200 psi before installation.

Installation Notes

Installation is typically performed by qualified pipefitters or maintenance technicians. Depressurize and drain the coolant circuit completely before disconnecting or installing any fittings. Verify that the hose inside diameter, material, and pressure rating are compatible with the system before assembly. Push-Lok barb fittings require the correct Parker-compatible hose series to achieve a secure, leak-free connection — do not substitute non-compatible hose types.
