Constructed from polyoxymethylene (POM), a high-rigidity acetal thermoplastic, the fitting accepts 5\/16 inch OD tubing on each end and holds rated pressure up to 300 psi. The tan-colored body is suited for fluid transfer applications in pneumatic and low-pressure hydraulic systems. Installation requires only pushing the tube into the fitting until it seats, making it a fast and repeatable connection for production, maintenance, and service environments.\u003c\/p\u003e\n\u003cp\u003eThis bulkhead union is used in applications where tubing must pass through and be secured to a panel, enclosure wall, or chassis. Typical install scenarios include pneumatic control panels, refrigeration equipment line sets, fluid distribution manifolds, and HVAC auxiliary drain or fluid-sensing lines. The POM body resists many common fluids and provides dimensional stability across a moderate temperature range. It is sold individually and is appropriate for both original equipment manufacturing builds and field replacement work performed by plumbers, HVAC technicians, and mechanical service pros.\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\u003eBulkhead configuration allows panel-mount tube pass-through and securing\u003c\/li\u003e\n  \u003cli\u003eRated to 300 psi for use in pneumatic and low-pressure fluid systems\u003c\/li\u003e\n  \u003cli\u003ePolyoxymethylene (POM) body offers high rigidity and chemical resistance\u003c\/li\u003e\n  \u003cli\u003eAccepts 5\/16 inch OD tubing on both ends for a straight-through union\u003c\/li\u003e\n  \u003cli\u003eTan color provides quick visual identification during installation and inspection\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement or new-installation push-to-connect bulkhead union for systems using 5\/16 inch OD tubing in pneumatic or low-pressure fluid applications.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation is performed by plumbers, HVAC technicians, or mechanical trades familiar with push-to-connect fittings. Before servicing an existing line, depressurize and de-energize the system completely. Ensure the tube end is cut cleanly and squarely with no burrs before insertion — a ragged cut is the most common cause of leaks with push-to-connect fittings. Verify the panel hole diameter matches the bulkhead fitting body before mounting to ensure a secure, leak-free seal.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFitting Type\u003c\/strong\u003e: Bulkhead Union\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eConnection Style\u003c\/strong\u003e: Push-To-Connect\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eTube Outside Diameter\u003c\/strong\u003e: 5\/16 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaximum Pressure\u003c\/strong\u003e: 300 psi\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBody Material\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: 0.05 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: A5BU5-MG\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"PARKER","offers":[{"title":"Default Title","offer_id":51539000918322,"sku":"A5BU5-MG","price":17.51,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/9aafb43f0549f67e576597a7024e2c20_262b70ee-a0ab-480a-82c0-e028ba619d43.jpg?v=1785832400","url":"https:\/\/voomisupply.com\/products\/parker-a5bu5-mg-bulkhead-union-fitting-5-16-inch-od","provider":"Voomi Supply","version":"1.0","type":"link"}
