Built with an acetal co-polymer body in gray, the 20779P uses a push-in connection for tool-free tube insertion, making field installation fast and repeatable. It is rated for pressures from 100 to 170 psi and operates across a temperature range of 34 to 150 degrees F. The union design allows the valve to be serviced or replaced without cutting or disturbing the surrounding tubing run. Licensed plumbers, HVAC technicians, and industrial pipe fitters are the typical installers of this fitting.\u003c\/p\u003e\n\u003cp\u003eThe 20779P is suited for residential and light commercial applications where backflow prevention is needed in plastic push-in tubing systems. Common use cases include compressed air distribution, pneumatic controls, water supply lines, and fluid transfer systems where acetal co-polymer construction is appropriate for the media being conveyed. The push-in end connection accepts standard tubing sizes at the 3\/8-inch nominal port without additional fittings, adapters, or thread sealants.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003ePush-in connection allows tool-free tube insertion and secure retention\u003c\/li\u003e\n  \u003cli\u003eUnion body style permits in-line service or replacement without cutting tubing\u003c\/li\u003e\n  \u003cli\u003eAcetal co-polymer construction resists moisture and common chemicals in fluid systems\u003c\/li\u003e\n  \u003cli\u003eRated from 100 to 170 psi for compatibility with typical pneumatic and plumbing line pressures\u003c\/li\u003e\n  \u003cli\u003eOperating temperature range of 34 to 150 degrees F covers most indoor service environments\u003c\/li\u003e\n  \u003cli\u003eCompact profile at 2.05 inches long supports installation in tight spaces\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a direct-fit replacement for 3\/8-inch nominal push-in union check valve applications in plastic tubing systems where acetal co-polymer body material is specified.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eShut off system pressure and relieve line pressure completely before removing or installing any check valve. Verify tubing is cut cleanly and squarely before inserting into the push-in port to ensure a leak-free seal. Confirm the flow-direction arrow on the valve body is oriented correctly before pressurizing the system. This fitting category falls under IPC and IFGC guidelines when used in relevant applications; verify local code compliance before installation.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNominal Size\u003c\/strong\u003e: 3\/8 inch\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eConnection Type\u003c\/strong\u003e: Push-In\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePressure Rating\u003c\/strong\u003e: 100 to 170 psi\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eTemperature Range\u003c\/strong\u003e: 34 to 150 degrees F\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBody Material\u003c\/strong\u003e: Acetal Co-Polymer\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eColor\u003c\/strong\u003e: Gray\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLength\u003c\/strong\u003e: 2.05 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHeight\u003c\/strong\u003e: 0.75 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWidth\u003c\/strong\u003e: 0.7 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.015 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: MIDLAND INDUSTRIES\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 20779P\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"MIDLAND INDUSTRIES","offers":[{"title":"Default Title","offer_id":67948871680306,"sku":"20779P","price":49.22,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/1a33a69c3e84b3b04100fdaa90034652.jpg?v=1791675355","url":"https:\/\/voomisupply.com\/products\/midland-industries-20779p-union-check-valve-3-8-in-push-in","provider":"Voomi Supply","version":"1.0","type":"link"}
