Dixon Valve Coupling 2940404C Brass Barb Fitting 1/4 in

Product Description

The DIXON VALVE COUPLING 2940404C is a brass rigid tube shank barb fitting designed for push-on hose connections in fluid-handling and pneumatic systems. The shank accepts a 1/4 inch barb and is sized for 1/4 inch OD tubing. Constructed entirely of brass, this fitting provides reliable corrosion resistance across a wide service temperature range of -40 degrees F to 150 degrees F. The compact overall length of 1.88 inches suits tight plumbing runs. Plumbers, HVAC technicians, and fluid-system installers use this type of fitting to make quick, secure hose-to-tube connections without threading or flaring.

This rigid tube shank barb fitting is suited for residential and light commercial applications where push-on hose assemblies connect to copper, brass, or compatible rigid tubing. Typical installations include low-pressure water lines, pneumatic circuits, and general fluid transfer systems where a permanent or semi-permanent hose attachment is required. The brass construction makes it appropriate for potable water, compressed air, and mild chemical service within the rated temperature limits.

Key Features

• Brass construction for corrosion resistance in water, air, and mild fluid service

Compatibility

Designed as an OEM-style push-on barb fitting for use with 1/4 inch ID flexible hose and 1/4 inch OD rigid tubing in low-pressure fluid and pneumatic plumbing assemblies.

Installation Notes

Installation is typically performed by licensed plumbers or qualified HVAC and fluid-system technicians. Shut off and depressurize the line before installing or removing any barb fitting. Push-on barb fittings rely on hose clamps or interference fit for retention — verify hose clamp torque and hose ID compatibility before pressurizing the system. Follow all applicable IPC and local plumbing code requirements for the specific fluid service.
