It features a 1\/4-18 male NPTF threaded connection and a 1\/4 inch body diameter, making it a compact, reliable fitting for connecting air hoses and pneumatic tools. With a maximum working pressure of 300 psi and an operating temperature range of -40 to 250 degrees F, the B12 handles demanding shop and field conditions. Licensed HVAC technicians, plumbers, mechanics, and general contractors commonly use this coupler in air tool and compressor line assemblies.\u003c\/p\u003e\n\u003cp\u003eThe B12 is suited for light industrial, automotive service, and general trade applications where Tru-Flate Automotive interchange compatibility is required. It installs on compressed air distribution lines, portable compressor hoses, and pneumatic tool connections. The threaded male NPTF design creates a pressure-tight seal without the need for additional sealant in most applications. At 2.05 inches overall length, it fits standard hose end assemblies without adding significant bulk to the connection.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eTru-Flate Automotive interchange standard for broad coupler and plug compatibility\u003c\/li\u003e\n  \u003cli\u003e1\/4-18 male NPTF thread for pressure-tight connections\u003c\/li\u003e\n  \u003cli\u003e300 psi maximum working pressure rated for demanding pneumatic service\u003c\/li\u003e\n  \u003cli\u003eBrass construction provides corrosion resistance in compressed air environments\u003c\/li\u003e\n  \u003cli\u003eWide temperature range: -40 to 250 degrees F\u003c\/li\u003e\n  \u003cli\u003eCompact 2.05 inch overall length with 0.75 inch hex for easy wrenching\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use with Tru-Flate Automotive interchange pneumatic systems.

Depressurize and bleed down the air line fully before removing or installing any coupler. Use an appropriately sized wrench on the 0.75 inch hex to achieve a proper seal without over-torquing the brass body. Inspect the NPTF threads and mating surfaces for damage before assembly.\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\/4-18\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Type\u003c\/strong\u003e: Male NPTF\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBody Diameter\u003c\/strong\u003e: 0.25 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 2.05 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHex Size\u003c\/strong\u003e: 0.75 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: Brass\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: 10\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.19 pounds\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eConnection Type\u003c\/strong\u003e: Threaded\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eUNSPSC Code\u003c\/strong\u003e: 40141734\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: PARKER\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: B12\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"PARKER","offers":[{"title":"Default Title","offer_id":51538288967986,"sku":"B12","price":34.21,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/46a62be60896e02369d4702ee321242b.jpg?v=1785821945","url":"https:\/\/voomisupply.com\/products\/parker-b12-pneumatic-hose-coupler-1-4-in-tru-flate-brass","provider":"Voomi Supply","version":"1.0","type":"link"}
