It features a 1\/4 inch body diameter with a 3\/8 inch male NPT threaded connection and conforms to the Industrial Interchange standard, making it one of the most widely used coupler profiles in the trade. Rated to 300 psi maximum working pressure and capable of operating across a temperature range of -40 degrees F to 250 degrees F, this coupler is built for reliable daily use in shop, industrial, and field service environments. Licensed HVAC techs, plumbers, mechanics, and general contractors rely on this type of fitting as a standard connection point on air hoses and pneumatic tools.\u003c\/p\u003e\n\u003cp\u003eThe 155 coupler is suited for residential and light commercial shop environments as well as industrial production and maintenance settings where Industrial Interchange pneumatic fittings are the site standard. It is commonly used on compressed air distribution lines, portable compressor setups, and pneumatic tool quick-connect systems. The brass body provides resistance to corrosion in humid or outdoor service conditions. Its threaded MNPT connection makes installation straightforward on standard NPT-ported air lines, manifolds, and tool inlets.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eIndustrial Interchange profile — compatible with the most common quick-connect coupler standard in trade use\u003c\/li\u003e\n  \u003cli\u003eBrass construction for corrosion resistance and durability in compressed air service\u003c\/li\u003e\n  \u003cli\u003e3\/8 inch MNPT threaded connection for standard NPT air line fittings\u003c\/li\u003e\n  \u003cli\u003e1\/4 inch body diameter matches standard quarter-inch pneumatic hose and tool inlet sizing\u003c\/li\u003e\n  \u003cli\u003eRated to 300 psi maximum working pressure for typical shop and industrial compressor systems\u003c\/li\u003e\n  \u003cli\u003eWide temperature range of -40 degrees F to 250 degrees F supports varied service environments\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a standard Industrial Interchange brass coupler for use with 3\/8 inch MNPT-ported pneumatic hose assemblies and air line components accepting a 1\/4 inch body coupler.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation is performed by a qualified pneumatic technician or mechanic. Always depressurize the air line and bleed residual pressure before removing or installing any coupler fitting. Apply thread sealant tape or compound to the MNPT threads per standard practice before tightening to avoid air leaks. Do not exceed the rated maximum working pressure of 300 psi on the connected system.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoupler Type\u003c\/strong\u003e: Coupler\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInterchange Type\u003c\/strong\u003e: Industrial Interchange\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBody Diameter\u003c\/strong\u003e: 1\/4 inch\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Size\u003c\/strong\u003e: 3\/8 inch\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Type\u003c\/strong\u003e: MNPT\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Standard\u003c\/strong\u003e: NPT\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eConnection Type\u003c\/strong\u003e: Threaded\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaximum Working Pressure\u003c\/strong\u003e: 300 psi\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaximum Temperature\u003c\/strong\u003e: 250 degrees F\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMinimum Temperature\u003c\/strong\u003e: -40 degrees F\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: Brass\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.14 pounds\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: COILHOSE PNEUMATICS\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 155\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"COILHOSE PNEUMATICS","offers":[{"title":"Default Title","offer_id":51559016857906,"sku":"155","price":21.94,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/0d0cf540efb554a15fe6d040816e0ee9.jpg?v=1786425832","url":"https:\/\/voomisupply.com\/products\/coilhose-pneumatics-155-pneumatic-hose-coupler-1-4-in-brass","provider":"Voomi Supply","version":"1.0","type":"link"}
