This coupler features a 3\/8-inch female NPT (FNPT) threaded connection and a 1\/4-inch body diameter, making it a compact, reliable fitting for connecting air hoses to tools, regulators, or manifolds. Built from brass, it handles a maximum working pressure of 300 psi and an operating temperature range of -40 to 250 degrees F. It follows the ARO interchange standard, ensuring broad compatibility with ARO-style quick-disconnect systems. Licensed plumbers, pipefitters, and HVAC-R technicians regularly use this type of coupler in shop, field, and mechanical-room compressed-air applications.\u003c\/p\u003e\n\u003cp\u003eThe 141 coupler is suited for residential and light commercial compressed-air systems where ARO-standard fittings are specified. Typical installations include pneumatic tool connections, air compressor outlet lines, and shop-air distribution drops. The FNPT thread allows direct connection to standard pipe-threaded ports on regulators, manifolds, and hose assemblies. Its brass construction resists corrosion in typical shop-air environments. The ARO interchange design means it mates with ARO-style plugs and couplers already in the field, reducing the need to change out existing fittings on tools or hose reels.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eARO interchange standard — mates with ARO-style quick-disconnect plugs already in service\u003c\/li\u003e\n  \u003cli\u003e3\/8-inch FNPT thread for direct connection to standard pipe-threaded ports\u003c\/li\u003e\n  \u003cli\u003e1\/4-inch body diameter compact form factor for tight-space installations\u003c\/li\u003e\n  \u003cli\u003eBrass construction resists corrosion in compressed-air service\u003c\/li\u003e\n  \u003cli\u003eRated to 300 psi maximum working pressure\u003c\/li\u003e\n  \u003cli\u003eWide temperature range: -40 to 250 degrees F\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an ARO interchange replacement coupler compatible with ARO-style quick-disconnect pneumatic systems using a 3\/8-inch FNPT threaded inlet and a 1\/4-inch body diameter.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation is performed by a qualified technician or pipefitter following applicable compressed-air safety practices. Depressurize and lock out the air supply before removing or installing any pneumatic fitting. Apply appropriate thread sealant to the FNPT threads per shop practice, and verify the connection is fully seated and leak-free before returning the system to service. Do not exceed the rated 300 psi working pressure.\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: ARO\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Type\u003c\/strong\u003e: FNPT\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Size\u003c\/strong\u003e: 3\/8 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBody Diameter\u003c\/strong\u003e: 1\/4 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: Brass\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\u003eWeight\u003c\/strong\u003e: 0.29 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: 141\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"COILHOSE PNEUMATICS","offers":[{"title":"Default Title","offer_id":51558917603634,"sku":"141","price":24.11,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/8276543fe57491cf45dd4eb8102f77b2.jpg?v=1786422851","url":"https:\/\/voomisupply.com\/products\/coilhose-pneumatics-141-pneumatic-coupler-3-8-fnpt-brass","provider":"Voomi Supply","version":"1.0","type":"link"}
