It accepts tubing with a 4 mm outside diameter and connects to an M5 x 0.8 threaded port. The body is constructed from brass with a polybutylene collet, rated for a maximum working pressure of 145 psi. This fitting is installed by licensed pipefitters, pneumatic system technicians, and automation maintenance professionals working on compressed air circuits and related fluid conveyance lines.\u003c\/p\u003e\n\u003cp\u003eThe KQ2H04-M5A is suited for pneumatic control systems in both light industrial and commercial applications. It is used wherever a compact M5-ported component  -  such as a solenoid valve, flow control, or manifold  -  requires a secure push-in tube connection without additional tooling. The fitting operates across a temperature range of 23 degrees F to 140 degrees F, making it appropriate for standard indoor pneumatic environments.\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 secure retention\u003c\/li\u003e\n  \u003cli\u003eM5 x 0.8 male thread for direct connection to M5-ported pneumatic components\u003c\/li\u003e\n  \u003cli\u003eRated to 145 psi maximum working pressure\u003c\/li\u003e\n  \u003cli\u003eBrass body construction for durability and corrosion resistance in pneumatic service\u003c\/li\u003e\n  \u003cli\u003eRoHS compliant  -  suitable for use in environmentally regulated applications\u003c\/li\u003e\n  \u003cli\u003eCompact overall length of 17.70 mm supports tight-clearance installations\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as a replacement or expansion fitting for pneumatic systems using 4 mm outside diameter tubing and M5 x 0.8 threaded ports, consistent with SMC KQ2 series push-to-connect fitting standards.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation is performed by pneumatic or mechanical technicians. Depressurize the system fully and verify zero pressure before removing or installing fittings. Ensure the tube end is cut cleanly and squarely before inserting into the collet to achieve a proper seal. Thread engagement should be hand-tight plus a controlled number of turns per the fitting manufacturer's guidance  -  do not overtighten brass threads into soft-ported bodies.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: Brass body, Polybutylene collet\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eThread Size\u003c\/strong\u003e: M5 x 0.8\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eTube Outside Diameter\u003c\/strong\u003e: 4 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: 17.70 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: KQ2H04-M5A\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"SMC","offers":[{"title":"Default Title","offer_id":51960763220274,"sku":"KQ2H04-M5A","price":22.98,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/adf1c9ddda7f85e6a7895d8fc66f4bb3.jpg?v=1789946571","url":"https:\/\/voomisupply.com\/products\/smc-pneumatics-kq2h04-m5a-push-to-connect-fitting-m5","provider":"Voomi Supply","version":"1.0","type":"link"}
