Constructed from brass with polybutylene compatibility, this fitting accepts a 12 mm outside diameter tube and threads into a 1\/2 inch port. It is rated for a maximum working pressure of 145 psi, making it suitable for compressed air, water, and similar fluid-handling systems. The overall assembled length is approximately 1.64 inches. Licensed plumbers, pipefitters, and pneumatic system technicians are the typical installers of this fitting type.\u003c\/p\u003e\n\u003cp\u003eThis connector is used in plumbing manifolds, pneumatic control panels, HVAC controls, and light industrial fluid distribution systems where a secure, leak-resistant push-to-connect interface is required. The 1\/2 inch thread allows direct integration into standard ported valves, manifolds, fittings, and equipment ports. It is sold individually, making it practical for targeted replacement or single-point installation on existing systems.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003ePush-to-connect design enables fast, tool-free tube insertion and removal\u003c\/li\u003e\n  \u003cli\u003eBrass body construction provides corrosion resistance and long service life\u003c\/li\u003e\n  \u003cli\u003eRated to 145 psi maximum working pressure\u003c\/li\u003e\n  \u003cli\u003eAccepts 12 mm outside diameter tubing\u003c\/li\u003e\n  \u003cli\u003e1\/2 inch thread for compatibility with standard ported equipment\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 connector fitting for pneumatic and plumbing systems requiring a 12 mm OD tube connection at a 1\/2 inch threaded port.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation is performed by licensed plumbers or qualified pneumatic system technicians. Before servicing any fitting, depressurize the line completely and verify pressure is at zero before disconnecting or installing components. Ensure the tube end is cut cleanly and squarely, and that the tube is fully seated before pressurizing the system. Thread engagement should comply with applicable IPC or local plumbing code requirements for the installation environment.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: Brass, Polybutylene\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eTube Outside Diameter\u003c\/strong\u003e: 12 mm\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Size\u003c\/strong\u003e: 1\/2 inch\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaximum Working Pressure\u003c\/strong\u003e: 145 psi\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 41.60 mm (approximately 1.64 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.01 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: KCH12-04S\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"SMC","offers":[{"title":"Default Title","offer_id":52118015934770,"sku":"KCH12-04S","price":18.2,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/fb1c4fc3b194ff7cafe19d6c7bca1f72_c52e8c1f-1969-47e1-876c-0f22202040d4.jpg?v=1790082037","url":"https:\/\/voomisupply.com\/products\/smc-pneumatics-kch12-04s-push-to-connect-tube-fitting","provider":"Voomi Supply","version":"1.0","type":"link"}
