It creates a secure, tool-free inline connection in compressed air and pneumatic brake line systems where Department of Transportation compliance is required. Rated to 150 psi with a working temperature range of -40 to 200 degrees F, this union is built for demanding mobile and commercial vehicle applications. The all-brass construction resists corrosion and withstands vibration common in vehicular environments. Licensed HVAC technicians, fleet mechanics, and plumbing pros working on air brake or pneumatic systems will find this fitting a straightforward drop-in solution.\u003c\/p\u003e\n\u003cp\u003eThe 621000M is used in D.O.T.-compliant pneumatic systems, most commonly air brake circuits on commercial trucks, trailers, and other regulated vehicles. It is also suitable for general compressed air plumbing where push-to-connect brass fittings are specified. The union configuration allows an inline connection or reconnection of two 10mm tubing runs without additional tools, making it practical for field repairs and new installations alike.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eD.O.T.-rated construction meets federal requirements for air brake and pneumatic brake line systems\u003c\/li\u003e\n  \u003cli\u003eDual 10mm push-to-connect ports allow fast, tool-free tubing insertion on both sides\u003c\/li\u003e\n  \u003cli\u003e150 psi maximum working pressure suits standard compressed air brake circuits\u003c\/li\u003e\n  \u003cli\u003eWide temperature range of -40 to 200 degrees F handles extreme operating environments\u003c\/li\u003e\n  \u003cli\u003eSolid brass body provides corrosion resistance and mechanical durability\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style D.O.T. brass union for systems using 10mm push-to-connect tubing in pneumatic and air brake plumbing applications.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation is typically performed by qualified fleet mechanics or pneumatic system technicians. Depressurize the air system completely before disconnecting or installing any fitting. Ensure tubing ends are cut cleanly and squarely with no burrs before inserting into the push-to-connect ports, as irregular cuts can compromise the seal. Verify compliance with applicable D.O.T. regulations and any relevant vehicle or facility codes before placing the system back in service.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eConnection Size 1\u003c\/strong\u003e: 10mm\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eConnection Type 1\u003c\/strong\u003e: Push-to-Connect\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eConnection Size 2\u003c\/strong\u003e: 10mm\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eConnection Type 2\u003c\/strong\u003e: Push-to-Connect\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaximum Working 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: 0.65 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLength\u003c\/strong\u003e: 1.9 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWidth\u003c\/strong\u003e: 0.65 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.1 pounds\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: MIDLAND INDUSTRIES\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 621000M\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"MIDLAND INDUSTRIES","offers":[{"title":"Default Title","offer_id":67948851659058,"sku":"621000M","price":17.3,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/a2118036dfc9097a86b8a5221ad11cbf_89cddcfa-0c2b-44ea-914c-e54e2d408628.jpg?v=1791674968","url":"https:\/\/voomisupply.com\/products\/midland-industries-621000m-dot-union-10mm-push-to-connect-brass","provider":"Voomi Supply","version":"1.0","type":"link"}
