Dixon Valve Coupling MSC1240406K Barbed Hose Fitting

Product Description

The DIXON VALVE COUPLING MSC1240406K is a brass barbed hose fitting designed to connect 1/4-inch inside diameter hose to a 3/8-inch female threaded port. It features a hose barb on one end and a female swivel ball-end on the other, allowing rotational adjustment during installation to reduce hose strain and simplify alignment. The fitting uses NPSM thread standard for the female connection. Constructed from brass, it resists corrosion in moderate fluid and air service applications. Plumbers, pipefitters, and general fluid-handling technicians install this type of fitting where a secure, leak-resistant barb-to-thread transition is needed.

This fitting suits residential and light commercial fluid transfer, compressed air, and low-pressure water line applications. It is appropriate wherever a 1/4-inch ID hose must terminate at a 3/8-inch female threaded port. The swivel ball-end design helps where hose routing creates angular misalignment at the connection point, reducing stress on both the hose and the threaded port. It is sold and packaged as a single unit.

Key Features

• Brass construction provides corrosion resistance for fluid, air, and water service
• Female swivel ball-end allows rotational adjustment to ease hose routing and reduce strain
• 3/8-inch NPSM female thread with 0.75-inch hex head for wrench engagement
• 0.25-inch barb size matches 1/4-inch ID hose for a secure grip
• Threaded connection type for straightforward installation with standard hand tools
• Single-unit packaging with no minimum order beyond one piece

Compatibility

Designed as an OEM-style replacement or direct-install barbed hose fitting for systems using 1/4-inch inside diameter hose terminated at a 3/8-inch NPSM female threaded port.

Installation Notes

A licensed plumber or qualified pipefitter should install this fitting in systems subject to local code requirements. Depressurize and drain the line fully before removing any existing fitting or making a new connection. Use an appropriately sized wrench on the 0.75-inch hex head to seat the female swivel end without over-tightening, which can crack brass fittings. Ensure the barb is fully inserted into the hose and secured with an appropriate clamp before returning the line to service.
