Built from brass with polybutylene components, this fitting accepts 12mm outside diameter tubing and allows technicians to route lines through panels, enclosures, or bulkheads without tools for tube insertion. It is rated to 145 psi maximum working pressure and carries RoHS compliance. Licensed HVAC technicians, industrial plumbers, and pneumatic system installers use this type of fitting when routing compressed air or compatible fluid lines through a fixed partition while maintaining a secure, leak-resistant connection on both sides.\u003c\/p\u003e\n\u003cp\u003eThis fitting is suited for residential and light commercial pneumatic systems, control panel builds, and compressed air distribution where a through-panel tube connection is required. The M22x1 thread engages a standard panel or manifold port, and the push-to-connect design on both ends speeds up tube termination during installation or service. It is appropriate for systems operating within the rated temperature window, such as equipment rooms, mechanical spaces, and light industrial enclosures where 12mm OD tubing is standard practice.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003ePush-to-connect design on both ends for tool-free tube insertion and removal\u003c\/li\u003e\n  \u003cli\u003eBulkhead configuration allows through-panel routing of pneumatic lines\u003c\/li\u003e\n  \u003cli\u003eBrass body with polybutylene components for durability and media compatibility\u003c\/li\u003e\n  \u003cli\u003eRated to 145 psi maximum working pressure\u003c\/li\u003e\n  \u003cli\u003eM22x1 thread for secure panel or manifold mounting\u003c\/li\u003e\n  \u003cli\u003eRoHS compliant construction\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style push-to-connect bulkhead fitting for pneumatic systems using 12mm outside diameter tubing with an M22x1 threaded panel port.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation should be performed by a qualified pneumatic systems technician or licensed plumber. De-pressurize and isolate the system completely before removing or installing any fittings. Verify the panel or manifold bore matches the M22x1 thread before installation, and confirm the tubing outside diameter is 12mm before seating the tube into the push-to-connect end. Do not exceed the 145 psi maximum working pressure or operate outside the rated temperature range of 23 to 140 degrees F.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaximum Working Pressure\u003c\/strong\u003e: 145 psi\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eTube Outside Diameter\u003c\/strong\u003e: 12mm\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Size\u003c\/strong\u003e: M22x1\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Type\u003c\/strong\u003e: UNF\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 34.70mm\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMinimum Working Temperature\u003c\/strong\u003e: 23 degrees F\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaximum Working Temperature\u003c\/strong\u003e: 140 degrees F\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: Brass, Polybutylene\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eConnection Type\u003c\/strong\u003e: Push-to-Connect\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.5 pounds\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eStandards\u003c\/strong\u003e: RoHS\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eUNSPSC Code\u003c\/strong\u003e: 27121700\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: SMC PNEUMATICS\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: KQ2E12-00A\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"SMC","offers":[{"title":"Default Title","offer_id":52023084319026,"sku":"KQ2E12-00A","price":20.29,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/b58ef1be24fc8a6dfeba41e96b35c839_679d8d80-8884-4447-9911-57b0137957dd.jpg?v=1790013790","url":"https:\/\/voomisupply.com\/products\/smc-pneumatics-kq2e12-00a-bulkhead-union-fitting-12mm","provider":"Voomi Supply","version":"1.0","type":"link"}
