Built from brass with a polybutylene body, this fitting accepts 5\/32-inch OD tubing on both ends and handles up to 145 psi working pressure. It is suited for compressed air lines, instrumentation tubing, and light fluid distribution in industrial and commercial environments. Licensed technicians and mechanical contractors working with pneumatic control systems will find this fitting straightforward to install without specialized crimping or threading tools.\u003c\/p\u003e\n\u003cp\u003eThis fitting is used in pneumatic control panels, automated equipment, and process piping runs where fast, repeatable tube connections are required. Its straight union configuration allows inline splicing of same-diameter tubing runs. The operating temperature range of 23 degrees F to 140 degrees F makes it appropriate for indoor industrial and light commercial installations. It ships individually and is well-suited for maintenance, repair, and operations stock as well as new system builds.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003ePush-to-connect design allows fast, tool-free tube insertion and removal\u003c\/li\u003e\n  \u003cli\u003eAccepts 5\/32-inch OD tubing on both ends for inline union connections\u003c\/li\u003e\n  \u003cli\u003eRated to 145 psi maximum working pressure\u003c\/li\u003e\n  \u003cli\u003eBrass and polybutylene construction for durability in pneumatic service\u003c\/li\u003e\n  \u003cli\u003eOperating temperature range: 23 degrees F to 140 degrees F\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 union fitting for pneumatic and fluid transfer systems using 5\/32-inch OD tubing, compatible with standard pneumatic control and instrumentation lines operating within the rated pressure and temperature limits.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation is typically performed by mechanical or pneumatic technicians. Before servicing any pneumatic line, depressurize the system completely and verify zero pressure at the connection point. Ensure tubing ends are cut cleanly and squarely with no burrs before inserting into the fitting to achieve a proper seal. Verify the system does not exceed the 145 psi pressure or 140 degrees F temperature ratings during operation.\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\u003eConfiguration\u003c\/strong\u003e: Union Straight\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eTube Outside Diameter\u003c\/strong\u003e: 5\/32 inches\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: 27.60 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\u003eMaterial\u003c\/strong\u003e: Brass, Polybutylene\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\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: KQ2H03-00A\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"SMC","offers":[{"title":"Default Title","offer_id":52073000370482,"sku":"KQ2H03-00A","price":14.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/a384a53a08e159131980f7fb19cc99c0_261829f3-1113-4baa-bfbf-d1d75f74e097.jpg?v=1790050205","url":"https:\/\/voomisupply.com\/products\/smc-pneumatics-kq2h03-00a-push-to-connect-union-fitting","provider":"Voomi Supply","version":"1.0","type":"link"}
