It features a 3\/8-inch body diameter, accepts a 1\/4-inch MNPT threaded connection, and is rated for pressures up to 300 psi. The steel construction with a nickel-plated finish provides corrosion resistance and durability under repeated connect-disconnect cycles. This coupler follows the Tru-Flate automotive interchange profile, making it a straightforward drop-in fit for shops and service facilities already running Tru-Flate-compatible tooling and fittings. Licensed HVAC techs, plumbers, and automotive air tool users will recognize this as standard shop hardware installed by maintenance personnel and trades professionals alike.\u003c\/p\u003e\n\u003cp\u003eThis coupler is suited for compressed air distribution systems in automotive service bays, general workshop environments, and light industrial applications. It is typically installed at the end of an air supply line or drop to provide a quick-connect point for air tools, blow guns, or inflation equipment. The Tru-Flate automotive interchange profile is one of the most widely used coupling standards in North American automotive shops, and this coupler integrates directly into existing Tru-Flate-compatible setups without adapters. The rated temperature range of -40 degrees F to 250 degrees F supports both cold-weather startup conditions and higher-temperature ambient shop environments.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eTru-Flate automotive interchange profile for broad compatibility with existing shop fittings\u003c\/li\u003e\n  \u003cli\u003e1\/4-inch MNPT threaded connection for standard pipe thread installation\u003c\/li\u003e\n  \u003cli\u003e3\/8-inch body diameter for adequate flow capacity in typical air tool applications\u003c\/li\u003e\n  \u003cli\u003e300 psi maximum working pressure rating\u003c\/li\u003e\n  \u003cli\u003eSteel body with nickel-plated finish for corrosion resistance and durability\u003c\/li\u003e\n  \u003cli\u003eRated from -40 degrees F to 250 degrees F for wide operating temperature range\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement or addition for compressed air systems using Tru-Flate automotive interchange couplers with 1\/4-inch MNPT threaded connections.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation is performed by maintenance technicians or trades professionals familiar with compressed air systems. Depressurize the air supply line completely before removing or installing any coupler. Apply thread sealant tape to the MNPT threads per standard practice and tighten to hand-tight plus a firm wrench turn, avoiding over-tightening that can crack fittings. Verify the system is leak-free at full operating pressure before returning to service.\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 Size\u003c\/strong\u003e: 1\/4 inch\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Type\u003c\/strong\u003e: MNPT\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBody Diameter\u003c\/strong\u003e: 3\/8 inches\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: 593\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"COILHOSE PNEUMATICS","offers":[{"title":"Default Title","offer_id":51564258328882,"sku":"593","price":34.95,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/390b7e435522bd979c8c372b7011f09f_7ab55d20-eac9-43a4-8743-e894c2f3121e.jpg?v=1786515527","url":"https:\/\/voomisupply.com\/products\/coilhose-pneumatics-593-pneumatic-hose-coupler-3-8-in","provider":"Voomi Supply","version":"1.0","type":"link"}
