Constructed from brass and polybutylene with a white finish, this connector handles a maximum working pressure of 145 psi and accommodates a 4 mm outside diameter tube. The overall length is approximately 15.90 mm (0.63 inches). It uses a universal 1\/8 inch thread type, making it compatible with a range of standard pneumatic port configurations. Licensed trades and industrial maintenance personnel install this fitting in compressed air lines, fluid control circuits, and instrumentation tubing runs.\u003c\/p\u003e\u003cp\u003eThis fitting is suited for light industrial and commercial pneumatic applications where a fast, reliable tube connection is needed at a threaded port. The push-to-connect design allows tubing to be inserted and locked without additional tools, reducing installation time. It is appropriate for use in automation equipment, pneumatic control panels, process instrumentation, and HVAC-adjacent compressed air circuits operating within the rated pressure range. The brass body and polybutylene construction provide corrosion resistance for typical dry compressed air service.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003ePush-to-connect design allows tool-free tube insertion and removal\u003c\/li\u003e\n\u003cli\u003eRated to 145 psi maximum working pressure\u003c\/li\u003e\n\u003cli\u003eAccepts 4 mm outside diameter tubing\u003c\/li\u003e\n\u003cli\u003eBrass body with polybutylene components for corrosion resistance\u003c\/li\u003e\n\u003cli\u003eUniversal 1\/8 inch thread type fits a wide range of standard ports\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 connector for pneumatic tubing systems using 4 mm outside diameter tubing and 1\/8 inch threaded ports operating at or below 145 psi.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eDepressurize and lock out the pneumatic system before installing or removing any tube fittings. Insert tubing straight into the fitting until it seats fully to ensure a proper seal. To release tubing, depress the collet ring while pulling the tube straight out. Follow applicable pneumatic system codes and the equipment manufacturer guidelines for fitting selection and torque when threading into a port body.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: Brass, Polybutylene\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eColor\u003c\/strong\u003e: White\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: 15.90 mm (0.63 inches)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThread Type\u003c\/strong\u003e: Universal 1\/8 inch\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: 1 pound\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: KQ2H04-U01A\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"SMC","offers":[{"title":"Default Title","offer_id":52098559344946,"sku":"KQ2H04-U01A","price":14.99,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/630ec3d45ee59094a61639f55e3fe026.jpg?v=1790067663","url":"https:\/\/voomisupply.com\/products\/smc-pneumatics-kq2h04-u01a-tube-fitting-connector-145-psi","provider":"Voomi Supply","version":"1.0","type":"link"}
