Dixon Valve Coupling DV-00205 Brass Barbed Hose Adapter

Product Description

The DIXON VALVE COUPLING DV-00205 is a brass barbed hose adapter designed to connect a 3/8 inch ID hose to a 1/2 inch male NPTF threaded port. The barbed end grips the inner wall of the hose to resist blowoff under pressure, while the MNPTF thread forms a dry-seal mechanical connection without requiring thread sealant. Brass construction provides corrosion resistance suitable for water, air, and a range of fluid transfer applications. This fitting is a standard item for plumbing mechanics, HVAC technicians, and maintenance technicians working with hose assemblies in both commercial and light industrial environments.

This adapter is used in systems where a threaded pipe port must transition to a flexible hose run. Common applications include condensate drain lines, water supply connections, equipment cooling circuits, and compressed air distribution at the point of use. The 3/8 inch barb accepts standard flexible hose of the corresponding inside diameter, and the 1/2 inch MNPTF end threads into a female NPT or NPTF port. Sold in a package quantity of five, making it practical for service vans and stocking distributors handling repeat installations.

Key Features

• Brass construction resists corrosion in water, air, and general fluid service
• MNPTF thread standard provides a dry-seal mechanical connection on the male end
• 3/8 inch ID barb end grips hose securely to resist pullout and blowoff
• 1/2 inch thread size mates with standard female NPT and NPTF ports
• Packaged in quantities of five for efficient restocking and service kits

Compatibility

Designed as an OEM-style barbed hose adapter for use with 3/8 inch inside diameter flexible hose assemblies terminating at a 1/2 inch female NPT or NPTF threaded port in plumbing, HVAC, and fluid transfer applications.

Installation Notes

Installation should be performed by a licensed plumber or qualified HVAC technician following applicable IPC and local plumbing code requirements. Shut off the water or fluid supply and relieve system pressure before removing or installing any fitting. Thread the MNPTF end in by hand first, then snug with an appropriately sized wrench — NPTF dry-seal threads do not require pipe dope or tape but may accept it. Secure the hose to the barb end with an appropriately sized hose clamp to maintain a leak-free connection.
