Dixon Valve Coupling 2740804C Female Hose Connector Brass

Product Description

The DIXON VALVE COUPLING 2740804C is a barbed push-on hose female connector designed for secure, leak-resistant hose terminations in fluid transfer systems. Constructed from solid brass, this fitting features a 1/4 inch NPTF threaded end and a 1/2 inch barb for push-on hose attachment. It measures 1.76 inches in length and weighs 1.8 pounds per package. The NPTF thread form provides a dry-seal mechanical connection, reducing reliance on thread sealants. Licensed plumbers, pipefitters, and fluid system technicians install this type of fitting in compressed air, hydraulic, fuel, and general liquid service lines where a threaded-to-barb transition is required.

This fitting is suited for residential and light commercial plumbing, pneumatic tool lines, irrigation systems, and industrial fluid transfer applications. The 1/2 inch barbed end accepts push-on hose of matching inside diameter, providing a fast, tool-light assembly. The 1/4 inch NPTF female thread connects to standard male-threaded ports, valves, and manifolds. Operating range spans -40 degrees F to 150 degrees F, making it appropriate for both indoor and outdoor service in moderate-temperature environments.

Designed as an OEM-style replacement or service fitting for systems requiring a 1/4 inch NPTF female threaded port with a 1/2 inch barbed push-on hose outlet.

Installation Notes

A licensed plumber or pipefitter should install this fitting in pressurized systems per applicable IPC and local code requirements. Shut off all fluid supply and depressurize the line before removing or installing any fitting. NPTF threads are designed for dry-seal assembly, but applying thread sealant tape per the system manufacturer's guidance is acceptable practice. Do not overtighten — hand-snug plus wrench turns per fitting size is standard; avoid cracking the brass body.
