Constructed from polypropylene, it handles pressures up to 150 psi and accommodates a 3\/8 inch OD tube on one side and a 1\/4 inch OD tube on the other. The push-to-connect design allows fast, repeatable installation in tight spaces. This fitting is suited for plumbing, HVAC, pool equipment, and fluid-handling systems where a panel or bulkhead separation is required between supply and use points.\u003c\/p\u003e\u003cp\u003eThis bulkhead union is commonly used in residential and light commercial applications where a tube line must pass cleanly through a panel, enclosure wall, or equipment housing. It is a practical choice for pool and spa chemical feed systems, water treatment equipment, and HVAC condensate or fluid-transfer lines. The reduced outlet size from 3\/8 inch to 1\/4 inch OD makes it useful for stepped-down flow paths within the same panel-penetration assembly.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003ePush-to-connect design eliminates the need for tools or thread sealant during installation\u003c\/li\u003e\n\u003cli\u003ePolypropylene construction provides resistance to many common chemicals and moisture\u003c\/li\u003e\n\u003cli\u003eRated to 150 psi for reliable service in pressurized fluid systems\u003c\/li\u003e\n\u003cli\u003eAccommodates 3\/8 inch OD inlet and 1\/4 inch OD outlet tubes in a single bulkhead-mount body\u003c\/li\u003e\n\u003cli\u003eCompact footprint at 1.75 inches height and length with a 1.06 inch width\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style push-to-connect bulkhead union replacement for systems using 3\/8 inch and 1\/4 inch OD tubing in plumbing, HVAC, pool, or fluid-transfer applications.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eThis fitting is typically installed by licensed plumbers, HVAC technicians, or pool service professionals. Before installation, shut off all fluid supply pressure and depressurize the line completely. Insert tubing fully into each port until the collet seats to ensure a secure, leak-free connection. To release tubing, depress the collet ring before pulling the tube free — do not pull against a seated collet without releasing it first.\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 OD\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: Polypropylene\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaximum Pressure\u003c\/strong\u003e: 150 psi\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHeight\u003c\/strong\u003e: 1.75 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWidth\u003c\/strong\u003e: 1.06 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLength\u003c\/strong\u003e: 1.75 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.05 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: PPB6BU4-MG\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"PARKER","offers":[{"title":"Default Title","offer_id":51541017559346,"sku":"PPB6BU4-MG","price":14.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/ae30aa34d0ee2c91893958467ed2ab8b.jpg?v=1785867381","url":"https:\/\/voomisupply.com\/products\/parker-ppb6bu4-mg-bulkhead-union-fitting-3-8-x-1-4-in-od","provider":"Voomi Supply","version":"1.0","type":"link"}
