Parker PC308 Hose Barb Straight Coupler 0.5 in 200 Psi

Product Description

The PARKER PC308 is a brass hose barb straight coupler designed for use in fluid-handling and cooling applications where reliable, leak-resistant connections are required. Rated to 200 psi maximum working pressure and suitable for temperatures ranging from -20 degrees F to 400 degrees F, this non-valved coupler accepts 0.5-inch inside diameter hose and features a threaded connection type on a 3/8-inch body diameter. It belongs to the Parker Moldmate series and is installed by hydraulic, industrial, and mechanical technicians working with coolant distribution and related fluid systems.

The PC308 is engineered for die casting equipment and mold coolant lines, where consistent flow and pressure integrity are critical. Its straight hose barb configuration simplifies installation in tight runs and inline connections. The non-valved design allows unrestricted flow when connected, making it well suited for permanent or semi-permanent coolant circuit assemblies in industrial environments. The Moldmate series designation indicates compatibility with Parker's standardized quick-connect coupling ecosystem used widely in industrial mold cooling setups.

Installation Notes

Installation should be performed by a qualified mechanical or hydraulic technician. Depressurize and drain the fluid system completely before removing or installing any fittings. Verify hose inside diameter matches the 0.5-inch barb before assembly, and ensure the threaded connection is properly engaged and sealed to prevent leaks under working pressure. Follow applicable industry and facility safety standards when working on pressurized fluid systems.
