Parker PC308-BP Push-lok Hose Barb Straight Coupler Brass

Product Description

The PARKER PC308-BP is a brass Push-Lok hose barb straight coupler designed for use in fluid handling and cooling applications. It accepts a 0.5-inch inside diameter hose and carries a maximum working pressure of 200 psi. The body diameter is 3/8 inch and the coupler size is 0.375 inches. The shaft is non-threaded on the hose-connection side, while the fitting uses a threaded connection type on the mating end. Rated for temperatures from -20 degrees F to 400 degrees F, this coupler suits demanding industrial environments where reliable, leak-resistant connections are required. Licensed trades and industrial maintenance technicians install this type of fitting in pressurized fluid circuits.

The PC308-BP belongs to the Parker Moldmate series, which targets die casting equipment and mold coolant lines. It is well suited to applications where consistent flow and pressure integrity are critical, such as temperature control circuits in injection molding and die casting operations. The straight coupler geometry simplifies inline installations where hose routing does not require a bend or elbow. The brass construction resists corrosion in water-based and light oil coolant media commonly used in mold cooling systems.

Key Features

• Brass construction provides corrosion resistance in water-based coolant and light oil media
• 0.5-inch hose inside diameter accommodates standard Push-Lok hose
• 200 psi maximum working pressure rated for pressurized cooling circuits
• Wide temperature range from -20 degrees F to 400 degrees F
• Non-threaded shaft end for tool-free Push-Lok hose assembly
• Straight body geometry for clean inline installations

Compatibility

Designed for use with die casting equipment and mold coolant lines as part of the Parker Moldmate series. Accepts 1/2-inch inside diameter Push-Lok hose.

Installation Notes

Installation should be performed by a qualified industrial maintenance technician or pipefitter. Depressurize and drain the fluid circuit fully before disconnecting or installing any fittings. Confirm hose inside diameter and system pressure rating are within the limits of this fitting before installation. Inspect the hose end for cuts or deformation prior to seating it onto the barb to ensure a secure, leak-free connection.
