It accepts 1\/2-inch tubing on both ends using push-to-connect fittings, allowing fast, tool-free connections through a panel or bulkhead wall. Rated to 150 psi and built to handle temperatures from -40 to 200 degrees F, this fitting is suited for compressed air, pneumatic controls, and similar service lines where a secure through-panel connection is required. The all-brass construction resists corrosion and holds up in demanding mechanical and industrial environments.\u003c\/p\u003e\u003cp\u003eThis bulkhead union is used where tubing lines must pass through a cabinet wall, frame rail, enclosure panel, or similar divider while maintaining a leak-free, pressure-rated seal on both sides. Typical applications include pneumatic control systems, truck and trailer air lines, and compressed air distribution panels. The push-to-connect design on both ends makes it a practical choice for technicians working in tight spaces or high-volume production environments where speed and repeatability matter.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eD.O.T.-rated construction for use in regulated pneumatic and air brake system applications\u003c\/li\u003e\n\u003cli\u003ePush-to-connect on both ends accepts 1\/2-inch tubing without tools or thread sealant\u003c\/li\u003e\n\u003cli\u003e150 psi working pressure rating\u003c\/li\u003e\n\u003cli\u003eOperating temperature range of -40 to 200 degrees F\u003c\/li\u003e\n\u003cli\u003eSolid brass body resists corrosion in air, water, and light oil service\u003c\/li\u003e\n\u003cli\u003eBulkhead-style design mounts through panels or enclosure walls to route tubing cleanly\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as a D.O.T.-rated OEM-style replacement or new-installation bulkhead union for 1\/2-inch push-to-connect pneumatic tubing systems.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation is typically performed by qualified pneumatic or fleet maintenance technicians. Shut down and depressurize the system completely before removing or installing any fitting. Ensure the panel or bulkhead material is rated for the cutout size and clamping load required by the fitting body. Verify that tubing is cut cleanly and squarely and inserted to full depth to achieve a proper push-to-connect seal.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eConnection Size\u003c\/strong\u003e: 1\/2 inch (both ends)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eConnection Type\u003c\/strong\u003e: Push-to-Connect (both ends)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWorking Pressure\u003c\/strong\u003e: 150 psi\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eTemperature Range\u003c\/strong\u003e: -40 to 200 degrees F\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: Brass\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHeight\u003c\/strong\u003e: 1.1 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLength\u003c\/strong\u003e: 2.05 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWidth\u003c\/strong\u003e: 1.2 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.345 pounds\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eStandard Information\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eBrand\u003c\/strong\u003e: MIDLAND INDUSTRIES\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 820800\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"MIDLAND INDUSTRIES","offers":[{"title":"Default Title","offer_id":67952048570674,"sku":"820800","price":40.58,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/128f6ae6ff431bfba74c732cf9e8258d_d5b9a6c3-c025-4cdc-8421-5939ea444a1c.jpg?v=1791744877","url":"https:\/\/voomisupply.com\/products\/midland-industries-820800-dot-bulkhead-union-1-2-in","provider":"Voomi Supply","version":"1.0","type":"link"}
