Built to ARO interchange standards, it accepts a 1\/4-18 Female NPTF threaded connection and features a 1\/4 inch body diameter. The coupler is rated for a maximum working pressure of 300 psi and operates across a temperature range of -40 degrees F to 250 degrees F. At 1.83 inches overall length, it is a compact inline connection point suitable for tool lines, pneumatic circuits, and shop air distribution. HVAC service technicians, industrial mechanics, and plumbing contractors are the typical installers.\u003c\/p\u003e\u003cp\u003eThis coupler fits into pneumatic systems requiring ARO-style interchange couplings. It is well suited for residential and light commercial shop air setups, pneumatic tool connections, and compressed air manifold branch lines. The female NPTF threaded entry seals reliably under pressure without a sealant in many applications, though thread condition and fitment should always be confirmed at installation. The Series 50 designation aligns with standard ARO interchange body sizing commonly found in trade and industrial environments.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eARO interchange standard for broad tool and fitting compatibility\u003c\/li\u003e\n\u003cli\u003eBrass construction for corrosion resistance in compressed air service\u003c\/li\u003e\n\u003cli\u003e300 psi maximum working pressure rating\u003c\/li\u003e\n\u003cli\u003eFemale NPTF 1\/4-18 thread for a pressure-tight threaded seal\u003c\/li\u003e\n\u003cli\u003eWide service temperature range: -40 degrees F to 250 degrees F\u003c\/li\u003e\n\u003cli\u003eCompact 1.83 inch overall length for tight installation spaces\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an ARO interchange replacement coupler compatible with Series 50 pneumatic coupling systems using 1\/4 inch body diameter fittings and 1\/4-18 Female NPTF threaded connections.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation is typically performed by industrial mechanics, HVAC technicians, or plumbing contractors familiar with pneumatic system fittings. Depressurize and isolate the air line completely before removing or installing any coupler. Inspect the mating plug and thread condition before assembly, and apply thread sealant per the fitting manufacturer guidance if the application requires it. Follow applicable OSHA and compressed air safety standards for the work environment.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: 50\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInterchange Type\u003c\/strong\u003e: ARO\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoupling Type\u003c\/strong\u003e: Coupler\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThread Type\u003c\/strong\u003e: Female NPTF\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThread Size\u003c\/strong\u003e: 1\/4-18\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eBody Diameter\u003c\/strong\u003e: 1\/4 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaximum Working Pressure\u003c\/strong\u003e: 300 psi\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 1.83 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 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\u003eConnection Type\u003c\/strong\u003e: Threaded\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.2033 pounds\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: B53\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"PARKER","offers":[{"title":"Default Title","offer_id":51540419838258,"sku":"B53","price":38.12,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/d6e17b8cbcdda9cf64b42cf7bfe1d139.jpg?v=1785854651","url":"https:\/\/voomisupply.com\/products\/parker-b53-pneumatic-hose-coupler-aro-interchange-brass","provider":"Voomi Supply","version":"1.0","type":"link"}
