Dixon Valve Coupling 2721006C Hose Male Connector Brass

Product Description

The DIXON VALVE COUPLING 2721006C is a barbed push-on hose male connector machined from brass, designed to create a secure threaded-to-hose transition in fluid transfer lines. It features a 3/8-inch NPTF male thread on one end and a 5/8-inch barb on the other, allowing a push-on hose to seat firmly without additional clamps in low-pressure applications. Rated to 350 psi maximum working pressure, this fitting handles a wide temperature range from -40 degrees F to 150 degrees F, making it suitable for a broad range of liquid and pneumatic service lines. Plumbers, pipefitters, and fluid-system technicians install this type of connector where a threaded port must transition to a barbed hose end.

This connector is used in residential and light commercial plumbing, pneumatic tool lines, irrigation systems, and general industrial fluid transfer applications. The NPTF thread standard ensures a pressure-tight seal through thread interference, reducing reliance on sealant tape alone. At 2.34 inches in length, it fits in tight plumbing runs where a compact barb-to-thread adapter is needed. The brass construction resists corrosion in water service and holds up well in low-pressure air lines.

Key Features

• 3/8-inch NPTF male thread for pressure-tight interference fit
• 5/8-inch barb accommodates push-on hose with matching inside diameter
• Brass construction for corrosion resistance in water and air service
• 350 psi maximum working pressure for demanding fluid transfer lines
• Wide temperature range: -40 degrees F to 150 degrees F
• Compact 2.34-inch length suits tight installation spaces

Compatibility

Designed as an OEM-style replacement or standard service fitting for threaded ports requiring a 3/8-inch NPTF male connection transitioning to a 5/8-inch inside diameter push-on barb hose.

Installation Notes

Installation is performed by licensed plumbers or qualified pipefitters following applicable IPC or IFGC guidelines for fluid system connections. Apply thread sealant or PTFE tape to the NPTF threads before installation, as NPTF threads rely on thread interference for sealing but sealant reduces galling risk. Shut off and depressurize the fluid system completely before removing or installing any fittings. Do not overtighten brass fittings, as the material is softer than steel and cross-threading or over-torquing can damage threads.
