Dixon Valve Coupling DV-00323 Hose Insert Fitting

Product Description

The DIXON VALVE COUPLING DV-00323 is a stainless steel barbed hose insert fitting designed to create a secure, leak-resistant connection between a threaded pipe or port and a flexible hose. The male NPT threaded end measures 3/8 inch and the barbed end accepts hose with a 5/8 inch inside diameter. Stainless steel construction provides corrosion resistance in wet, chemical-exposed, or high-humidity service environments. This fitting is installed by licensed plumbers, HVAC technicians, and industrial maintenance professionals working on fluid transfer, coolant, and low-pressure line assemblies.

This hose insert is suited for residential and light commercial applications where a reliable barb-to-NPT transition is required. Typical installations include water supply lines, coolant circuits, irrigation sub-assemblies, and fluid handling systems where a hose must terminate at a threaded port. The male NPT thread seals against female NPT fittings or tapped ports using thread sealant tape or compound. This package contains 2 fittings per unit.

Key Features

• Stainless steel body for corrosion resistance in wet and chemically aggressive environments
• 3/8 inch MNPT thread end for direct connection to standard NPT female ports
• 5/8 inch ID barb end sized for compatible flexible hose
• Barb-over-hose design grips hose securely, reducing pull-out risk
• Sold as a package of 2 fittings

Compatibility

Designed as an OEM-style replacement or maintenance fitting for fluid transfer systems requiring a 3/8 inch MNPT to 5/8 inch ID barbed hose connection.

Installation Notes

Installation is typically performed by a licensed plumber or qualified maintenance technician. Shut off and depressurize the fluid system before removing or installing any fitting. Apply PTFE tape or an appropriate thread sealant to the male NPT threads before assembly and tighten to fitting manufacturer guidelines using a properly sized wrench. Secure the hose over the barb with a correctly rated hose clamp to ensure a leak-free seal.
