Constructed from polyoxymethylene (POM), this fitting joins tubes with different outside diameters — 3\/8 inch and 1\/4 inch OD — without the need for tools or thread sealing compounds. It is rated to 300 psi and is suited for use in compressed air, light hydraulic, and instrumentation tubing systems. Licensed plumbers, HVAC technicians, and industrial maintenance professionals install this type of fitting in both new construction and service work.\u003c\/p\u003e\n\u003cp\u003eThis union fitting is used in applications requiring a quick, reliable connection between two tube runs of differing OD sizes. Common installation scenarios include pneumatic control circuits, HVAC equipment tubing, refrigeration instrument lines, and process control plumbing where fast, leak-resistant connections are required. The tan POM body makes it easy to distinguish from metal fittings in mixed-material installations.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003ePush-to-connect design — no tools required for tube insertion\u003c\/li\u003e\n  \u003cli\u003eRated to 300 psi working pressure\u003c\/li\u003e\n  \u003cli\u003eReduces 3\/8 inch OD tube to 1\/4 inch OD tube in a single union body\u003c\/li\u003e\n  \u003cli\u003ePolyoxymethylene (POM) construction — chemical-resistant and dimensionally stable\u003c\/li\u003e\n  \u003cli\u003eTan body color for easy visual identification in multi-fitting installations\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use with 3\/8 inch and 1\/4 inch OD tubing in push-to-connect pneumatic and fluid systems. Compatible tubing materials typically include nylon, polyurethane, and semi-rigid poly tubing appropriate for the rated pressure range.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eShut off system air or fluid pressure and bleed the line before disconnecting or installing any push-to-connect fitting. Ensure tube ends are cut cleanly and squarely with no burrs or deformation before insertion. Verify that the tubing OD matches the fitting port size exactly — mismatched tubing will not seal reliably. This fitting type is typically installed by HVAC technicians, pipefitters, or instrumentation mechanics in accordance with applicable system design standards.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eConnection Type\u003c\/strong\u003e: Push-To-Connect\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFitting Type\u003c\/strong\u003e: Union (Tube to Tube)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eTube Outside Diameter\u003c\/strong\u003e: 3\/8 x 1\/4 inches OD\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaximum Working 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\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: A6EU4-MG\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"PARKER","offers":[{"title":"Default Title","offer_id":51541294383410,"sku":"A6EU4-MG","price":15.6,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/05acf79af2a188ccfe54dbe95b70f4c4_dbd3971c-eafe-480a-a689-77746fe46eaa.jpg?v=1785871584","url":"https:\/\/voomisupply.com\/products\/parker-a6eu4-mg-push-to-connect-union-fitting-3-8x1-4","provider":"Voomi Supply","version":"1.0","type":"link"}
