Constructed from polyoxymethylene (POM), a high-rigidity acetal thermoplastic, this fitting accepts 1\/4-inch outside diameter tubing on all three ports and provides a secure, tool-free connection rated to 300 psi. The tan-colored POM body resists common chemicals and offers dimensional stability across a range of service temperatures. Lightweight at 0.02 pounds, it is well suited for inline tee connections where quick assembly and reliable seals are required. HVAC technicians, plumbers, and pneumatic system installers use this type of fitting to split or branch tubing runs without threading or soldering.\u003c\/p\u003e\n\u003cp\u003eThis union tee fitting is appropriate for use in residential and light commercial applications involving pneumatic control lines, condensate or low-pressure fluid tubing, and instrument air distribution. The push-to-connect design allows fast field assembly and disassembly, making it a practical choice for service technicians who need to branch or reconfigure tubing runs during installation or repair. It accepts standard 1\/4-inch OD tubing on all three ports, creating a symmetrical tee configuration with no preferred flow direction.\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 on all three ports\u003c\/li\u003e\n  \u003cli\u003eRated to 300 psi for use in pneumatic and low-pressure fluid systems\u003c\/li\u003e\n  \u003cli\u003ePOM (polyoxymethylene) body provides high rigidity and chemical resistance\u003c\/li\u003e\n  \u003cli\u003eAccepts 1\/4-inch OD tubing on all three ports for a symmetrical union tee configuration\u003c\/li\u003e\n  \u003cli\u003eLightweight construction at 0.02 pounds minimizes load on tubing assemblies\u003c\/li\u003e\n  \u003cli\u003eTan color allows easy visual identification in multi-fitting panel layouts\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style push-to-connect fitting for use with standard 1\/4-inch outside diameter tubing in pneumatic, HVAC control, and low-pressure fluid distribution systems.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation is performed by inserting clean, cut-square tubing fully into each port until it seats against the internal collet. Before servicing or replacing this fitting, depressurize the tubing circuit completely. To release tubing, depress the collet ring while pulling the tube straight out. Ensure tubing ends are cut square and free of burrs to maintain a leak-free seal.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eTube Outside Diameter\u003c\/strong\u003e: 1\/4 inch\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaximum Pressure\u003c\/strong\u003e: 300 psi\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: Polyoxymethylene (POM)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eColor\u003c\/strong\u003e: Tan\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eConnection Type\u003c\/strong\u003e: Push-to-connect, tube-to-tube\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFitting Configuration\u003c\/strong\u003e: Union Tee\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.02 pounds\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eUNSPSC Code\u003c\/strong\u003e: 27121707\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: A4TU4-MG\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"PARKER","offers":[{"title":"Default Title","offer_id":51540387987762,"sku":"A4TU4-MG","price":14.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/41e76545a624fbae9beeeed3b807d1a7.jpg?v=1785853967","url":"https:\/\/voomisupply.com\/products\/parker-a4tu4-mg-push-to-connect-union-tee-1-4-inch-od","provider":"Voomi Supply","version":"1.0","type":"link"}
