Constructed from polypropylene in a tan finish, this fitting accepts 3\/8 inch OD on one side and 1\/4 inch OD on the other, allowing a reducer-style bulkhead connection in a single component. It is rated to 150 psi and provides a quick, tool-free tube insertion and release mechanism suited to pneumatic and fluid distribution systems. Plumbers, HVAC technicians, and industrial service pros use this fitting where tubing must pass cleanly through a bulkhead or enclosure panel.\u003c\/p\u003e\u003cp\u003eThis fitting is appropriate for light commercial and residential applications where polypropylene compatibility is acceptable for the fluid or gas media in use. Typical installations include tubing routed through control panel walls, equipment enclosures, or partition boards where a secure, leak-resistant through-wall connection is needed. The push-to-connect design speeds service and replacement compared to compression or barb-style alternatives.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003ePush-to-connect mechanism for tool-free tube insertion and removal\u003c\/li\u003e\n\u003cli\u003eBulkhead union configuration for through-panel or through-wall tube routing\u003c\/li\u003e\n\u003cli\u003eReducer configuration: 3\/8 inch OD inlet to 1\/4 inch OD outlet\u003c\/li\u003e\n\u003cli\u003ePolypropylene construction offers chemical resistance for a range of fluid media\u003c\/li\u003e\n\u003cli\u003eRated to 150 psi working pressure\u003c\/li\u003e\n\u003cli\u003eTan color for easy visual identification in multi-fitting installations\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style push-to-connect replacement fitting for tube-to-tube bulkhead connections using 3\/8 inch and 1\/4 inch OD tubing in pneumatic or compatible fluid systems.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation is performed by qualified plumbing or HVAC technicians. Depressurize and drain the system completely before removing or installing any fitting. Ensure tubing ends are cut cleanly and squarely and are free of burrs before insertion to achieve a proper seal. Follow all applicable local plumbing and mechanical codes when routing tubing through panels or structural members.\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\u003eColor\u003c\/strong\u003e: Tan\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaximum Working Pressure\u003c\/strong\u003e: 150 psi\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.03 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: PP6BU4\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"PARKER","offers":[{"title":"Default Title","offer_id":51540035469618,"sku":"PP6BU4","price":16.19,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/a92289bab37520d267aba5a65f1d8f46_1ea3c634-5415-4b35-95a9-d3725fd7f62a.jpg?v=1785845541","url":"https:\/\/voomisupply.com\/products\/parker-pp6bu4-bulkhead-union-3-8-x-1-4-inch-od-polypropylene","provider":"Voomi Supply","version":"1.0","type":"link"}
