Dixon Valve Coupling 2781212C Hose Female Connector

Product Description

The DIXON VALVE COUPLING 2781212C is a barbed push-on hose female connector designed for secure, leak-resistant hose assembly connections in fluid transfer systems. Machined from solid brass, this fitting features a 3/4 inch NPSM threaded end for connection to female-threaded ports and a 3/4 inch barb end that grips the inside diameter of compatible hose. At 2.36 inches in length and weighing 0.1 pounds, it is compact and lightweight. The brass construction provides corrosion resistance across a wide temperature range, making it a practical choice for plumbing, irrigation, and industrial fluid handling applications. Installation is straightforward for licensed plumbers and general contractors familiar with push-on barb and NPSM threaded fittings.

This connector is suited for use in both light industrial and commercial fluid systems where a reliable female threaded-to-barb transition is needed. The 3/4 inch barb accepts hose with a matching 3/4 inch inside diameter. With a maximum working pressure of 350 psi, it handles moderate-pressure water, air, and compatible fluid lines. Typical install scenarios include irrigation manifolds, water supply connections, and equipment plumbing where a push-on barb attachment is preferred over clamp or crimp fittings.

Key Features

• Brass construction for corrosion resistance and durability in wet environments
• 3/4 inch NPSM female thread for standard push-on hose connections
• 3/4 inch barb end sized for 3/4 inch inside diameter hose
• Rated to 350 psi maximum working pressure
• Wide temperature range: -40 degrees F to 150 degrees F
• Compact 2.36 inch length fits in tight plumbing spaces

Compatibility

Designed as an OEM-style replacement or new-install fitting for systems using 3/4 inch inside diameter push-on hose with a 3/4 inch NPSM female threaded port.

Installation Notes

This fitting is typically installed by licensed plumbers or qualified tradespeople familiar with NPSM thread standards and barbed hose fittings. Shut off fluid supply and relieve system pressure before installation or removal. Ensure hose inside diameter matches the 3/4 inch barb size for a proper push-on seal; a hose clamp is recommended to secure the barb connection. Verify thread compatibility before engaging the NPSM connection to avoid cross-threading or joint failure.
