It is designed to join two pneumatic lines of different outside diameters with a simple push-in connection, eliminating the need for tools or thread sealant at the tube connection point. Rated to a maximum working pressure of 145 psi and suitable for operating temperatures from 23 degrees F to 140 degrees F, this fitting is a compact, field-ready component used in compressed air and pneumatic control plumbing across industrial and commercial applications.\u003c\/p\u003e\u003cp\u003eThis reducer fitting is used in pneumatic tubing systems where a transition between tube sizes is required. It is typically installed on compressed air distribution lines, pneumatic actuator circuits, and control system plumbing in manufacturing, automation, and mechanical service environments. The push-to-connect design allows for fast, repeatable connections without secondary crimping or soldering tools, making it well suited for technicians assembling or servicing pneumatic control panels and distribution manifolds.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003ePush-to-connect design allows tool-free tube insertion and secure retention\u003c\/li\u003e\n\u003cli\u003eBrass body construction for durability in compressed air 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\u003eTube outside diameter of 3.20 mm with a stem outside diameter of 4.00 mm for size reduction\u003c\/li\u003e\n\u003cli\u003eRoHS compliant construction\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style push-to-connect plug-in reducer fitting for pneumatic tubing systems requiring a transition between compatible tube outside diameters in compressed air service applications.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation is performed by qualified pneumatic technicians or pipefitters. Depressurize and lock out the pneumatic circuit completely before removing or installing any tube fittings. Ensure tubing ends are cut cleanly and squarely with no burrs before insertion into the push-to-connect collet. Verify that tube outside diameter matches the fitting specification before assembly to ensure a leak-free connection.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaximum Working Pressure\u003c\/strong\u003e: 145 psi\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\u003eTube Outside Diameter\u003c\/strong\u003e: 3.20 mm\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eStem Outside Diameter\u003c\/strong\u003e: 4.00 mm\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 28.60 mm\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\u003eStandards\u003c\/strong\u003e: RoHS\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.1 pounds\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: KQ2R23-04A\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"SMC","offers":[{"title":"Default Title","offer_id":52015012675890,"sku":"KQ2R23-04A","price":14.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/30f7bd33d5b722eadc5182cf47b22e81_828b0e77-980e-4d69-b82f-496fa95d53bc.jpg?v=1790007432","url":"https:\/\/voomisupply.com\/products\/smc-pneumatics-kq2r23-04a-plug-in-reducer-fitting-145-psi","provider":"Voomi Supply","version":"1.0","type":"link"}
