Part of the Universal Series, it features a 1\/4 inch body diameter and a female NPSF threaded connection in a 3\/8-18 thread size. The coupler follows the Industrial Interchange standard, making it broadly compatible across pneumatic tooling and equipment setups. Rated for a maximum working pressure of 150 psi and a temperature range of -40 degrees F to 250 degrees F, this fitting is suited for demanding shop and industrial environments. HVAC, plumbing, and general mechanical contractors who rely on pneumatic tools will find this a straightforward, durable fitting solution.\u003c\/p\u003e\u003cp\u003eThis coupler is used in light to medium industrial pneumatic applications including air tool connections, compressor line hookups, and pneumatic control systems. The Industrial Interchange configuration is one of the most widely used coupling standards in North American shops and service environments, allowing connection to a broad range of pneumatic tools and accessories. The female NPSF thread seats directly onto standard male-threaded fittings. The brass construction resists corrosion and holds up well in environments where moisture exposure is common, such as compressed air lines that see condensation.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eIndustrial Interchange standard for broad pneumatic tool compatibility\u003c\/li\u003e\n\u003cli\u003eBrass construction for corrosion resistance in moist or humid environments\u003c\/li\u003e\n\u003cli\u003eFemale NPSF thread, 3\/8-18 size, for secure threaded connections\u003c\/li\u003e\n\u003cli\u003e1\/4 inch body diameter with an overall length of 2.21 inches\u003c\/li\u003e\n\u003cli\u003eRated to 150 psi maximum working pressure\u003c\/li\u003e\n\u003cli\u003eWide temperature range: -40 degrees F to 250 degrees F\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an Industrial Interchange style coupler compatible with standard 1\/4 inch body pneumatic fittings and tools using a 3\/8-18 female NPSF threaded connection.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation is performed by a qualified technician familiar with pneumatic systems. Always depressurize and bleed the air line completely before connecting or disconnecting couplers. Apply appropriate thread sealant to the NPSF threads to ensure a leak-free connection. Inspect threads and the coupler body for damage before installation and do not exceed the rated working pressure of 150 psi.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\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: Industrial\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: Universal\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: Brass\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThread Type\u003c\/strong\u003e: Female NPSF\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThread Size\u003c\/strong\u003e: 3\/8-18\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eBody Diameter\u003c\/strong\u003e: 1\/4 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 2.21 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHex Size\u003c\/strong\u003e: 0.81 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaximum Working Pressure\u003c\/strong\u003e: 150 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\u003eConnection Type\u003c\/strong\u003e: Threaded\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.23 pounds\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eUNSPSC Code\u003c\/strong\u003e: 40141734\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eStandard Information\u003c\/h4\u003e\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: UC-251-6FP\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"PARKER","offers":[{"title":"Default Title","offer_id":51540424950066,"sku":"UC-251-6FP","price":63.82,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/63d7f669359b659b2463d7e74cf4dcc6.jpg?v=1785854771","url":"https:\/\/voomisupply.com\/products\/parker-uc-251-6fp-pneumatic-coupler-1-4-in-brass","provider":"Voomi Supply","version":"1.0","type":"link"}
