The fitting accepts a 4 mm outside-diameter tube on one end and a 10 mm outside-diameter stem on the other, providing a secure, leak-resistant transition in compressed-air and pneumatic fluid-distribution systems. Constructed from brass with a polybutylene component, it is rated to 145 psi maximum working pressure and handles temperatures from 23 degrees F to 140 degrees F. Plumbers, pipefitters, and pneumatic system technicians install this fitting in light industrial and OEM machine-assembly applications.\u003c\/p\u003e\n\u003cp\u003eThis reducer fitting is suited for compressed-air lines, pneumatic control circuits, and fluid-conveyance tubing runs where two lines of differing diameters must be connected inline. Its push-to-connect design eliminates the need for thread sealing or crimping tools, making it appropriate for both initial system builds and field-service tube repairs. The compact overall length of 31.70 mm keeps the fitting envelope tight in panel-mount and manifold-adjacent installations common in light industrial and automation environments.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003ePush-to-connect design allows tool-free tube insertion and removal for fast field service\u003c\/li\u003e\n  \u003cli\u003eReduces from a 10 mm stem outside diameter to a 4 mm tube outside diameter in a single inline fitting\u003c\/li\u003e\n  \u003cli\u003eRated to 145 psi maximum working pressure for standard compressed-air service\u003c\/li\u003e\n  \u003cli\u003eOperating temperature range of 23 degrees F to 140 degrees F suits most indoor industrial environments\u003c\/li\u003e\n  \u003cli\u003eBrass and polybutylene construction for corrosion resistance in air and compatible fluid systems\u003c\/li\u003e\n  \u003cli\u003eRoHS compliant\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style push-to-connect reducer for pneumatic tubing systems using 4 mm and 10 mm outside-diameter tubing in compressed-air and fluid-distribution lines rated up to 145 psi.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation is performed by licensed pipefitters or pneumatic system technicians. Before servicing any pneumatic line, depressurize the system completely and verify zero pressure with a gauge before disconnecting any fittings. Ensure cut tubing ends are square and free of burrs before inserting into the push-to-connect collet to maintain a leak-free seal. Verify that tubing material and system pressure are within the rated limits of this fitting before placing the line back into service.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\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: 4 mm\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eStem Outside Diameter\u003c\/strong\u003e: 10 mm\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: 31.70 mm\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\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: KQ2R04-10A\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"SMC","offers":[{"title":"Default Title","offer_id":52041458319666,"sku":"KQ2R04-10A","price":14.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/30f7bd33d5b722eadc5182cf47b22e81_fdf5b81c-a787-43a3-8141-0bc7c98378c0.jpg?v=1790027742","url":"https:\/\/voomisupply.com\/products\/smc-pneumatics-kq2r04-10a-plug-in-reducer-fitting-145-psi","provider":"Voomi Supply","version":"1.0","type":"link"}
