Constructed from polyoxymethylene (POM), a rigid engineering-grade thermoplastic, this fitting handles working pressures up to 300 psi. It accepts a 5\/16 inch OD tube on one end and a 1\/4 inch OD tube on the other, making it a reducing union suitable for systems that step down tubing size. Plumbers, HVAC technicians, and fluid-system installers commonly use POM push-to-connect fittings in pneumatic, water, and light hydraulic line applications.\u003c\/p\u003e\n\u003cp\u003eThis fitting is suited for residential and light commercial installations where a quick, reliable tube-to-tube connection is needed between two different OD tubing sizes. Typical applications include instrument air lines, water purification plumbing, pneumatic control tubing, and condensate or fluid distribution systems. The push-to-connect design allows fast field assembly and straightforward tube removal when a release collar is depressed, reducing labor time on tight or repetitive installations.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003ePush-to-connect design — no tools, solvents, or compression sleeves required for assembly\u003c\/li\u003e\n  \u003cli\u003eReducing union configuration accepts 5\/16 inch OD on one port and 1\/4 inch OD on the other\u003c\/li\u003e\n  \u003cli\u003eRated to 300 psi working pressure\u003c\/li\u003e\n  \u003cli\u003ePolyoxymethylene (POM) body offers high rigidity, low moisture absorption, and chemical resistance for fluid-line service\u003c\/li\u003e\n  \u003cli\u003eTan color for quick visual identification in multi-line installations\u003c\/li\u003e\n  \u003cli\u003eCompact, lightweight construction at 0.02 pounds\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style push-to-connect replacement or new-install fitting for pneumatic, water, and fluid distribution systems using 5\/16 inch and 1\/4 inch OD tubing.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eDepressurize and drain the line completely before removing or installing any push-to-connect fitting. Ensure tube ends are cut square with no burrs or scratches in the insertion zone, as surface defects compromise the internal seal. Verify that tubing OD dimensions match the fitting ports exactly before insertion. This fitting is intended for use within its rated pressure limit — do not exceed 300 psi in service.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eTube Outside Diameter\u003c\/strong\u003e: 5\/16 x 1\/4 inches\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: A5UC4-MG\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"PARKER","offers":[{"title":"Default Title","offer_id":51540267073842,"sku":"A5UC4-MG","price":18.03,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/d8a382c8883e78b017a86cad6fde04b9.jpg?v=1785850753","url":"https:\/\/voomisupply.com\/products\/parker-a5uc4-mg-push-to-connect-union-tube-fitting","provider":"Voomi Supply","version":"1.0","type":"link"}
