Dixon dc20 Air Chief Pneumatic Coupler 1/4 in Female Npt

Product Description

The DIXON dc20 is a semi-automatic pneumatic quick-connect coupler built to the Industrial Interchange standard, designed for use in compressed air and pneumatic tool applications. The coupler features a straight orientation with a 1/4 inch Female NPT thread on one end and a 1/4 inch Female ISO-6150 Series B Industrial Interchange quick-disconnect interface on the other. Constructed from solid brass, the dc20 automatically shuts off airflow when disconnected, preventing uncontrolled pressure release. It is intended for installation by HVAC technicians, industrial maintenance professionals, and pneumatic system assemblers working with air lines, hose assemblies, and tool drops.

The dc20 fits applications requiring a reliable, field-proven Industrial Interchange coupler in light industrial, commercial, and shop environments. Because the Industrial Interchange pattern is widely adopted across manufacturers, this coupler is compatible with a broad range of pneumatic tool plugs and hose fittings built to the same interchange standard. On assembled hose and fitting combinations, the working pressure rating of the system is governed by whichever component carries the lower rating, measured at 70 degrees F.

Key Features

• Semi-automatic shut-off valve closes automatically when coupler is disconnected, reducing air loss and pressure hazards
• 1/4 inch Female NPT inlet threads directly onto standard air line fittings and manifolds
• 1/4 inch Female ISO-6150 Series B Industrial Interchange interface interchanges with many competing brands
• Straight body orientation simplifies inline hose and drop-line installations
• All-brass construction provides corrosion resistance suitable for compressed air service

Compatibility

Designed as an OEM-style Industrial Interchange quick-connect coupler compatible with 1/4 inch Female ISO-6150 Series B pneumatic plugs from many manufacturers following the Industrial Interchange standard.

Installation Notes

Installation is typically performed by qualified pneumatic or HVAC technicians. Always depressurize and bleed the air line completely before connecting or disconnecting any coupler. Apply thread sealant appropriate for pneumatic service to the NPT threads before installation, and do not over-tighten brass fittings. Verify that the assembled system pressure rating does not exceed the lower-rated component in the hose and fitting assembly.
