Constructed from polyoxymethylene (POM), a high-strength acetal resin, this fitting handles working pressures up to 300 psi. The push-to-connect design allows fast, tool-free tube insertion, making it a practical choice for HVAC controls technicians, pneumatic system installers, and plumbing professionals who need reliable inline branch connections. The tan-colored POM body resists moisture and common chemicals encountered in light industrial and mechanical system environments.\u003c\/p\u003e\u003cp\u003eThis fitting is suited for residential and light commercial applications where a Y-branch connection is needed between two tube runs. Typical install scenarios include pneumatic control tubing, instrument air lines, and fluid distribution manifolds. The 3\/8 inch by 1\/4 inch outside diameter configuration accommodates a reducing Y arrangement, allowing a single 3\/8 inch tube run to branch or transition to a 1\/4 inch tube run without additional adapters or fittings.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003ePush-to-connect design — no tools required for tube insertion or removal\u003c\/li\u003e\n\u003cli\u003e300 psi working pressure rating\u003c\/li\u003e\n\u003cli\u003ePolyoxymethylene (POM) construction for chemical and moisture resistance\u003c\/li\u003e\n\u003cli\u003eUnion Y configuration enables inline tube branching or reducing transitions\u003c\/li\u003e\n\u003cli\u003eAccommodates 3\/8 inch and 1\/4 inch OD tubing in a single fitting\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style push-to-connect fitting for use with 3\/8 inch and 1\/4 inch OD rigid or semi-rigid tubing in pneumatic, compressed air, and fluid distribution systems.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation is performed by trade professionals including HVAC controls technicians, pneumatic system installers, and pipefitters. Depressurize and de-energize the system completely before removing or installing any fittings. Ensure tubing ends are cut square and free of burrs before insertion to achieve a proper seal. Verify that working pressure does not exceed the rated limit of the fitting throughout the system.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eTube Outside Diameter\u003c\/strong\u003e: 3\/8 x 1\/4 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: Polyoxymethylene (POM)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaximum Working Pressure\u003c\/strong\u003e: 300 psi\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eColor\u003c\/strong\u003e: Tan\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.0249 pounds\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eUNSPSC Code\u003c\/strong\u003e: 27121707\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: A6UC4-MG\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"PARKER","offers":[{"title":"Default Title","offer_id":51542891659570,"sku":"A6UC4-MG","price":15.01,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/47b0e9afa34ffe79a09c18062229e4eb.jpg?v=1785910114","url":"https:\/\/voomisupply.com\/products\/parker-a6uc4-mg-union-y-push-to-connect-fitting-3-8x1-4","provider":"Voomi Supply","version":"1.0","type":"link"}
