Parker EZ-371-6HB Pneumatic Hose Coupling 3/8 in

Product Description

The PARKER EZ-371-6HB is a steel pneumatic hose coupling designed for compressed air and industrial pneumatic systems. Part of the E-Z Mate series, this coupler features a 3/8-inch body diameter and a hose barb thread type, connecting directly to 3/8-inch inside diameter hose without threaded fittings. It is rated for a maximum working pressure of 300 psi and handles a temperature range of -40 degrees F to 250 degrees F. The Industrial Interchange configuration makes it compatible with widely used shop air quick-connect setups. Licensed HVAC, mechanical, and industrial service technicians install this type of fitting in pneumatic tool circuits and equipment air supply lines.

This coupler is suited for light to medium industrial pneumatic applications including shop air distribution, pneumatic tooling circuits, and equipment maintenance setups. The hose barb connection style is commonly used in applications where tools or lines are installed and removed periodically. The Industrial Interchange design allows pairing with standard couplers and plugs found across most commercial and light industrial environments.

Key Features

• 3/8-inch body diameter with 3/8-inch inside diameter hose barb connection
• Steel construction for durability in shop and industrial environments
• Rated to 300 psi maximum working pressure
• Wide temperature range: -40 degrees F to 250 degrees F
• Industrial Interchange series for broad coupling compatibility
• Part of the E-Z Mate series for straightforward installation

Compatibility

Designed as an OEM-style Industrial Interchange coupler compatible with standard quick-connect pneumatic systems using 3/8-inch hose barb connections in commercial and light industrial air supply circuits.

Installation Notes

Depressurize and lock out the air supply line before installing or replacing pneumatic couplings. This coupler is typically installed by mechanical or industrial technicians using standard hand tools. Ensure the hose inside diameter matches the 3/8-inch barb before securing with an appropriate clamp. Verify the system operating pressure does not exceed the 300 psi rating of this fitting.
