Parker PC318 90 Degree Hose Barb Coupler 0.5 in 200 Psi

Product Description

The PARKER PC318 is a 90-degree hose barb coupler from the Moldmate series, designed for use in high-temperature fluid handling applications such as die casting equipment and mold coolant lines. Built from brass, this non-valved fitting accepts a 0.5-inch inside diameter hose and provides a threaded connection on the body side. It is rated for a maximum working pressure of 200 psi and handles temperatures from -20 degrees F up to 400 degrees F. Plumbers, pipefitters, and industrial maintenance technicians install this type of coupler where a 90-degree flow direction change is required in pressurized coolant or hydraulic fluid circuits.

The PC318 is suited for industrial fluid systems where controlled coolant routing is critical. Its primary listed applications are die casting equipment and mold coolant lines, where operating temperatures and pressures demand a durable metal fitting. The Moldmate series designation indicates it is engineered for the specific pressure and thermal requirements found in tooling and mold cooling circuits. The 90-degree barb geometry allows a hose to exit at a right angle from the body, reducing bend stress on the hose near the connection point.

Key Features

• 90-degree hose barb design routes hose at a right angle, reducing hose stress at the fitting
• 0.5-inch hose inside diameter barb fits standard half-inch ID hose
• Brass construction resists corrosion in coolant and water-based fluid service
• 200 psi maximum working pressure rated for pressurized coolant circuits
• Wide temperature range: -20 degrees F to 400 degrees F
• Non-valved body allows unrestricted flow when connected
• Threaded body connection, 3/8-inch body diameter for secure in-line installation

Compatibility

Listed for use with die casting equipment and mold coolant lines as part of the Parker Moldmate series. Designed as an OEM-style replacement or service fitting for industrial coolant systems requiring a 90-degree, 0.5-inch ID hose barb connection at up to 200 psi.

Installation Notes

Installation is typically performed by a licensed pipefitter or qualified industrial maintenance technician. Depressurize and drain the coolant circuit fully before removing or installing any fitting. Apply thread sealant appropriate for the fluid service to the threaded body connection per manufacturer and applicable plumbing code guidelines. Ensure the hose is fully seated over the barb and secured with an appropriate clamp rated for the operating pressure.
