Constructed from brass, it features a 1\/4 inch Male NPT inlet and a 1\/4 inch Female ISO-6150 Series B Industrial Interchange socket end. The coupler shuts off automatically when disconnected, preventing uncontrolled air release and helping to maintain line pressure integrity. It is installed by HVAC technicians, industrial mechanics, and pneumatic system technicians working with compressed air tool lines, hose assemblies, and shop air distribution systems.\u003c\/p\u003e\n\u003cp\u003eThis coupler is suited for use in industrial and commercial compressed air applications where a reliable, semi-automatic quick-connect fitting is required. Because it follows the Industrial Interchange design, it will mate with many other makes and brands of Industrial Interchange couplers and plugs. Pressure rating on hose assemblies is the lower of either the coupling rating or the hose rating at 70 degrees F. It is commonly used in tool rooms, service bays, and production floor air lines.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eSemi-automatic shut-off when disconnected, reducing air waste and improving safety\u003c\/li\u003e\n  \u003cli\u003eIndustrial Interchange design interchanges with many other manufacturer couplers and plugs\u003c\/li\u003e\n  \u003cli\u003eStraight body orientation for direct inline installations\u003c\/li\u003e\n  \u003cli\u003eBrass construction for corrosion resistance in compressed air service\u003c\/li\u003e\n  \u003cli\u003e1\/4 inch Male NPT thread for standard pipe and hose assembly connections\u003c\/li\u003e\n  \u003cli\u003e1\/4 inch Female ISO-6150 Series B socket end for broad plug compatibility\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned to interchange with many Industrial Interchange style couplers and plugs from other manufacturers.

Depressurize and bleed the air line completely before removing any existing coupler or fitting. Apply thread sealant appropriate for pneumatic service to the NPT threads before installation. Verify that the operating pressure of the assembled hose and coupler system does not exceed the lower pressure rating of either component at the service temperature.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: Brass\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBody Size\u003c\/strong\u003e: 1\/4 inch\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInlet Thread\u003c\/strong\u003e: 1\/4 inch Male NPT\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSocket End\u003c\/strong\u003e: 1\/4 inch Female ISO-6150 Series B Industrial Interchange\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShape (Orientation)\u003c\/strong\u003e: Straight\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOperation Type\u003c\/strong\u003e: Semi-Automatic\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eRated Temperature\u003c\/strong\u003e: 70 degrees F\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eStandard Information\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBrand\u003c\/strong\u003e: DIXON\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: dc21\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"DIXON","offers":[{"title":"Default Title","offer_id":51150110753074,"sku":"DC21","price":19.36,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/305986112.jpg?v=1778606261","url":"https:\/\/voomisupply.com\/products\/dixon-dc21-pneumatic-industrial-interchange-coupler-brass","provider":"Voomi Supply","version":"1.0","type":"link"}
