It features a 3\/8 inch male NPT (MNPT) threaded connection and a 1\/4 inch body diameter, conforming to Industrial Interchange standards for broad compatibility across pneumatic tool setups. Rated to 300 psi maximum working pressure and a temperature range of -40 to 250 degrees F, this coupler is built for demanding shop and field environments. It is installed by HVAC technicians, industrial mechanics, and pneumatic tool operators who require a reliable, leak-resistant connection point on air lines and manifolds.\u003c\/p\u003e\n\u003cp\u003eThis coupler is suited for use in residential, commercial, and light industrial pneumatic systems where Industrial Interchange-style fittings are the standard. Typical applications include connecting air hoses to compressors, pneumatic tools, and blow-gun assemblies. The brass construction resists corrosion in environments where moisture in compressed air lines is common. The MNPT thread type allows direct installation into standard NPT-tapped ports on air distribution equipment without adapters.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eIndustrial Interchange coupler style for broad cross-brand tool and hose compatibility\u003c\/li\u003e\n  \u003cli\u003e3\/8 inch MNPT threaded connection for direct NPT port installation\u003c\/li\u003e\n  \u003cli\u003e1\/4 inch body diameter for standard light-duty air line applications\u003c\/li\u003e\n  \u003cli\u003e300 psi maximum working pressure rating for typical shop air systems\u003c\/li\u003e\n  \u003cli\u003eOperating temperature range of -40 to 250 degrees F\u003c\/li\u003e\n  \u003cli\u003eBrass construction for corrosion resistance in moisture-exposed compressed air environments\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement or service fitting for pneumatic systems using Industrial Interchange standard couplers with 3\/8 inch MNPT threaded ports.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation is performed by qualified pneumatic technicians or mechanics. Always depressurize and bleed the air line completely before removing or installing any coupler. Apply thread sealant tape to the MNPT threads to ensure a leak-free connection, and tighten to snug using an appropriately sized wrench — avoid over-tightening brass fittings. Verify the system does not exceed the 300 psi maximum working pressure rating before returning the line to service.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eType\u003c\/strong\u003e: Coupler\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInterchange Type\u003c\/strong\u003e: Industrial\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Type\u003c\/strong\u003e: MNPT\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Size\u003c\/strong\u003e: 3\/8 inch\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBody Diameter\u003c\/strong\u003e: 1\/4 inch\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: Brass\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\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: 155A\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"COILHOSE PNEUMATICS","offers":[{"title":"Default Title","offer_id":51557686051122,"sku":"155A","price":36.09,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/3c45db294f6ce4a33df9005f65d80b49.jpg?v=1786392838","url":"https:\/\/voomisupply.com\/products\/coilhose-pneumatics-155a-pneumatic-hose-coupler-3-8-mnpt","provider":"Voomi Supply","version":"1.0","type":"link"}
