Built from nickel-plated brass, it accepts tubing with a 1\/4 inch outside diameter and connects to a stem with a 1\/2 inch outside diameter. It is rated to 250 psi maximum working pressure and handles temperatures from 0 degrees F to 160 degrees F. The Buna O-ring provides a reliable seal for both compressed air and water service. Plumbers, HVAC technicians, and industrial maintenance professionals install this fitting where quick, repeatable tube connections are required without soldering or threading.\u003c\/p\u003e\n\u003cp\u003eThis fitting is suited for residential and light commercial applications involving compressed air lines and water supply tubing. Typical install scenarios include pneumatic control systems, air tool drops, small-bore water lines, and equipment connections where tubing must be secured and released repeatedly during service. The 1\/4 inch OD tube size is common in instrumentation, refrigeration accessory lines, and low-pressure pneumatic circuits. The push-to-connect design reduces installation time compared to compression or flare fittings in accessible, low-vibration environments.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003ePush-to-connect design allows tool-free tube insertion and release\u003c\/li\u003e\n  \u003cli\u003eNickel-plated brass construction resists corrosion in wet and air service\u003c\/li\u003e\n  \u003cli\u003eRated to 250 psi maximum working pressure\u003c\/li\u003e\n  \u003cli\u003eOperating temperature range of 0 degrees F to 160 degrees F\u003c\/li\u003e\n  \u003cli\u003eBuna O-ring included for reliable sealing on compressed air and water\u003c\/li\u003e\n  \u003cli\u003eAccepts 1\/4 inch OD tubing with a 1\/2 inch OD stem connection\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use with compressed air and water systems using 1\/4 inch OD tubing.

Before installation, depressurize and isolate the line and verify the tubing cut is clean, square, and free of burrs to ensure a proper O-ring seal. Do not exceed the rated working pressure or temperature limits. Consult applicable plumbing codes such as the IPC for water service installations.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eConnection Type\u003c\/strong\u003e: Tube x Stem\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: Nickel-Plated Brass\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eTube Outside Diameter\u003c\/strong\u003e: 0.25 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eStem Outside Diameter\u003c\/strong\u003e: 0.5 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaximum Working Pressure\u003c\/strong\u003e: 250 psi\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMinimum Working Temperature\u003c\/strong\u003e: 0 degrees F\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaximum Working Temperature\u003c\/strong\u003e: 160 degrees F\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eO-Ring Material\u003c\/strong\u003e: Buna\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFor Use With\u003c\/strong\u003e: Compressed Air, Water\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePackage Quantity\u003c\/strong\u003e: 3 pieces\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDimensions\u003c\/strong\u003e: 3 inches L x 0.75 inches W x 6 inches H\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.2 pounds\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: PRO-SOURCE\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 2559011963PRO\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"PRO-SOURCE","offers":[{"title":"Default Title","offer_id":51730055463218,"sku":"2559011963PRO","price":16.54,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/d3c00b12624f497ebbf5105afaa74d55.jpg?v=1788710909","url":"https:\/\/voomisupply.com\/products\/pro-source-2559011963pro-push-to-connect-tube-stem-fitting","provider":"Voomi Supply","version":"1.0","type":"link"}
