Constructed from brass with polybutylene components, it handles a maximum working pressure of 145 psi and operates across a temperature range of 23 degrees F to 140 degrees F. The push-to-connect mechanism allows for tool-free tube insertion and secure, leak-resistant connections without threading or soldering. This fitting is suited for compressed air and pneumatic fluid transfer lines where a fast, reliable reducer connection is required.\u003c\/p\u003e\u003cp\u003eThe KQ2R10-12A is used in industrial and commercial pneumatic systems where tubing diameter transitions are needed inline. The 10mm outside diameter tube port reduces to a 12mm stem outside diameter, making it appropriate for routing compressed air lines through equipment assemblies, control panels, and automation systems. It is typically installed by industrial maintenance technicians, pneumatic system integrators, and mechanical contractors working with push-to-connect tubing networks.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003ePush-to-connect design allows fast, tool-free tube insertion and removal\u003c\/li\u003e\n\u003cli\u003eBrass construction with polybutylene components for durability in pneumatic service\u003c\/li\u003e\n\u003cli\u003eRated to 145 psi maximum working pressure\u003c\/li\u003e\n\u003cli\u003eOperating temperature range of 23 degrees F to 140 degrees F\u003c\/li\u003e\n\u003cli\u003eRoHS compliant construction\u003c\/li\u003e\n\u003cli\u003eCompact overall length of approximately 1.54 inches (39.20mm) for tight installations\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style push-to-connect reducer fitting compatible with 10mm outside diameter tubing on one end and a 12mm stem on the other, suitable for standard pneumatic tube fitting applications within the rated pressure and temperature limits.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation is performed by pneumatic system technicians or mechanical contractors. Depressurize and lock out the pneumatic system before removing or installing fittings. Verify tubing outside diameter matches the fitting port specification before insertion to ensure a proper seal. Inspect tubing ends for squareness and burrs prior to insertion, as damaged tube ends can compromise the connection seal.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eConnection Type\u003c\/strong\u003e: Push-to-Connect\u003c\/li\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: 10mm\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eStem Outside Diameter\u003c\/strong\u003e: 12mm\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: 39.20mm (approximately 1.54 inches)\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\u003eWeight\u003c\/strong\u003e: 0.1 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\u003ch4\u003eStandard Information\u003c\/h4\u003e\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: KQ2R10-12A\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"SMC","offers":[{"title":"Default Title","offer_id":51993323110706,"sku":"KQ2R10-12A","price":14.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/30f7bd33d5b722eadc5182cf47b22e81_bb852ca6-5274-4c02-a1eb-8df23b794d8e.jpg?v=1789991057","url":"https:\/\/voomisupply.com\/products\/smc-pneumatics-kq2r10-12a-plug-in-reducer-fitting-145-psi","provider":"Voomi Supply","version":"1.0","type":"link"}
