Built from steel with a nickel-plated finish, this coupler features a 3\/8 inch body diameter and a 1\/4 inch FNPT thread connection. It handles working pressures up to 300 psi and operates across a temperature range of -40 degrees F to 250 degrees F. The Tru-Flate Automotive interchange profile makes it a direct-fit replacement in shops already running that standard. Licensed HVAC techs, plumbers, and automotive service professionals install this part to connect air tools, hoses, and pneumatic supply lines quickly and securely.\u003c\/p\u003e\n\u003cp\u003eThis coupler is suited for both residential shop and commercial service bay applications where Tru-Flate Automotive interchange fittings are the shop standard. Typical install scenarios include compressed air distribution lines, pneumatic tool connections, and portable compressor setups. The threaded FNPT body allows direct installation into female-ported manifolds, hose ends, and tool inlets without additional adapters. It is a single-piece, inline coupler sold individually.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eTru-Flate Automotive interchange profile for compatibility with existing shop fittings of the same standard\u003c\/li\u003e\n  \u003cli\u003eSteel construction with nickel-plated finish for corrosion resistance in shop environments\u003c\/li\u003e\n  \u003cli\u003eRated to 300 psi maximum working pressure\u003c\/li\u003e\n  \u003cli\u003eWide operating temperature range: -40 degrees F to 250 degrees F\u003c\/li\u003e\n  \u003cli\u003e1\/4 inch FNPT threaded connection for direct inline installation\u003c\/li\u003e\n  \u003cli\u003e3\/8 inch body diameter for consistent airflow capacity\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement coupler for compressed air systems using the Tru-Flate Automotive interchange standard with 1\/4 inch FNPT threaded connections.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation is typically performed by a qualified pneumatic or mechanical technician. Always depressurize the air supply line and bleed residual pressure before removing or installing couplers. Apply thread sealant tape to the FNPT threads per standard shop practice to prevent air leakage. Verify that the replacement coupler interchange type matches the mating plug already in service before installation.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCoupling Type\u003c\/strong\u003e: Coupler\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInterchange Type\u003c\/strong\u003e: Tru-Flate Automotive\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: 1\/4 inch\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBody Diameter\u003c\/strong\u003e: 3\/8 inch\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: Steel\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFinish\u003c\/strong\u003e: Nickel-Plated\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eConnection Type\u003c\/strong\u003e: Threaded\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: 592\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"COILHOSE PNEUMATICS","offers":[{"title":"Default Title","offer_id":51562595352882,"sku":"592","price":31.64,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/8b8af47b656ce9f55c93259ef9b1f53e.jpg?v=1786480421","url":"https:\/\/voomisupply.com\/products\/coilhose-pneumatics-592-pneumatic-hose-coupler-3-8-in","provider":"Voomi Supply","version":"1.0","type":"link"}
