Dixon Valve 2ds3-b Pneumatic Qd Coupling Hose Barb Brass

Product Description

The DIXON VALVE 2ds3-b is a D-Series pneumatic quick disconnect coupling socket designed for industrial compressed air and pneumatic tool applications. This straight-body coupling features a 3/8 inch hose barb on one end and a 1/4 inch female ISO-6150 Series B industrial interchange fitting on the other, allowing fast connect and disconnect of air lines without tools. The body is machined from brass for corrosion resistance and durability, and the internal seal is Buna-N nitrile rubber, which holds up well across a broad range of operating temperatures and petroleum-based lubricant exposure. Pneumatic technicians, maintenance mechanics, and industrial service professionals install this type of coupling on air hoses, compressors, and pneumatic equipment.

This coupling is suited for use in industrial, manufacturing, and general maintenance environments where D-Series automatic interchange pneumatic fittings are the established standard. The hose barb end accepts 3/8 inch ID hose, which is a common size for shop air and pneumatic tool drops. The 1/4 inch female ISO-6150 Series B socket mates with standard male industrial interchange plugs widely used in North American pneumatic systems. Typical installation scenarios include compressed air distribution systems, portable compressor hose assemblies, and inline air tool connections.

Key Features

• D-Series automatic industrial interchange design for tool-free connect and disconnect
• 3/8 inch hose barb end accepts standard 3/8 inch ID air hose
• 1/4 inch female ISO-6150 Series B industrial interchange socket
• Straight-body orientation for in-line hose runs
• Brass construction resists corrosion in compressed air service
• Buna-N nitrile rubber seal compatible with air and petroleum-based lubricants

Compatibility

Designed as an OEM-style replacement or new-installation fitting compatible with D-Series automatic industrial interchange pneumatic quick disconnect systems using 3/8 inch ID hose barb connections and 1/4 inch female ISO-6150 Series B male plugs.

Installation Notes

Installation should be performed by a qualified pneumatic or mechanical technician. Always depressurize and bleed the air line completely before connecting or removing any quick disconnect fitting. Secure the hose barb with an appropriate hose clamp sized for 3/8 inch ID hose to prevent blowoff under pressure. Inspect the nitrile seal for cuts or deformation before placing the fitting into service.
