It accepts 3\/8 inch OD tubing on one end and 1\/4 inch OD tubing on the other, making it a reducing union for mismatched line sizes. The fitting body is constructed from polypropylene and is rated to 150 psi. It is used in pneumatic, fluid transfer, and light-duty process lines where a fast, leak-resistant connection is required. Plumbers, HVAC technicians, and industrial service pros install these fittings when speed and reusability matter.\u003c\/p\u003e\n\u003cp\u003eThis fitting is suited for residential and light commercial applications involving air lines, water supply tubing, and low-pressure fluid systems. The push-to-connect mechanism allows the fitting to be installed by hand — simply insert the tube to the stop — and released with a collet sleeve when removal is needed. It is a practical choice for tight spaces where wrench clearance is limited or where the line may need to be disconnected during servicing.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eReduces 3\/8 inch OD to 1\/4 inch OD in a single inline union fitting\u003c\/li\u003e\n  \u003cli\u003ePolypropylene construction resists corrosion and chemical exposure in compatible fluid service\u003c\/li\u003e\n  \u003cli\u003eRated to 150 psi for use in low-to-medium pressure pneumatic and fluid lines\u003c\/li\u003e\n  \u003cli\u003eTool-free installation — tube inserts and locks without fittings, clamps, or solder\u003c\/li\u003e\n  \u003cli\u003eCollet-release design allows the tube to be removed and reconnected during service\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style push-to-connect replacement union for systems using 3\/8 inch and 1\/4 inch OD tubing in low-pressure pneumatic or fluid transfer service.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation is performed by plumbers or HVAC technicians working on low-pressure lines. Before installing or removing the fitting, shut off and depressurize the line completely. Verify that the tube end is cut square and deburred before insertion to ensure a proper seal. Do not exceed the 150 psi pressure rating or use this fitting with fluids incompatible with polypropylene.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\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: Polypropylene\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePressure Rating\u003c\/strong\u003e: 150 psi\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHeight\u003c\/strong\u003e: 1.03 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWidth\u003c\/strong\u003e: 0.79 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLength\u003c\/strong\u003e: 1.02 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.04 pounds\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePackage Quantity\u003c\/strong\u003e: 1\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: PPB6TU4-MG\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"PARKER","offers":[{"title":"Default Title","offer_id":51541954134322,"sku":"PPB6TU4-MG","price":14.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/c756196b78f005d27e310eaf1300d85c_a93249c4-ca8c-4fb4-b3a6-c47d6b858cfe.jpg?v=1785888406","url":"https:\/\/voomisupply.com\/products\/parker-ppb6tu4-mg-push-to-connect-union-3-8-x-1-4-in-od","provider":"Voomi Supply","version":"1.0","type":"link"}
