Parker PC306V Hose Barb Straight Coupler 3/8 Inch 200 Psi

Product Description

The PARKER PC306V is a valved hose barb straight coupler designed for hydraulic and fluid-transfer systems requiring a reliable inline connection. Part of the Parker Moldmate series, this brass fitting accepts 3/8 inch hose and is rated to 200 psi, making it suitable for moderate-pressure hydraulic lines, coolant circuits, and industrial fluid applications. The built-in valve allows the line to be broken without full system drain-down, reducing fluid loss during service. Installation is handled by plumbers, hydraulic technicians, and industrial maintenance mechanics working on fluid-power or process-fluid systems.

The PC306V is suited for use in both light industrial and commercial fluid-handling applications where a compact, non-threaded barb connection is required. The Moldmate series is commonly found in injection molding cooling circuits, hydraulic control lines, and general-purpose liquid transfer systems. Operating temperature range spans from -20 degrees F to 400 degrees F, giving this coupler broad usability across heating, cooling, and process-fluid environments. Its valved design allows one side of the connection to seal when disconnected, limiting spillage and downtime during maintenance cycles.

Key Features

• Valved design seals upon disconnection to minimize fluid spillage during line service
• 200 psi pressure rating suitable for moderate-pressure hydraulic and coolant circuits
• 3/8 inch hose barb on a straight coupler body for direct inline connection
• Brass construction provides corrosion resistance in water-based and hydraulic fluid environments
• Wide temperature range: -20 degrees F to 400 degrees F
• Non-threaded shaft for push-and-barb installation without tools or thread sealant

Compatibility

Designed as an OEM-style replacement or service fitting for 3/8 inch hose barb connections in the Parker Moldmate series. Compatible with 3/8 inch inner diameter flexible hose in hydraulic, coolant, and fluid-transfer assemblies rated at or below 200 psi.

Installation Notes

Hydraulic technicians or licensed plumbers should depressurize and drain the affected fluid circuit before disconnecting or installing this fitting. Ensure hose is fully seated past all barb rings and secure with an appropriate clamp rated for the system pressure. Verify the hose inner diameter matches the 3/8 inch barb before installation to maintain a leak-free seal. Follow applicable industry standards and facility safety procedures when working on pressurized fluid systems.
