This SMC KQG2E07-00 bulkhead union tube fitting joins 1/4" OD tubing through a bulkhead. Two 1/2"-20 Unified National Fine (UNF) thread lock nuts hold the fitting securely to the bulkhead. The 316 stainless steel fitting is corrosion-resistant, the fluoroelastomer (FKM) seal and O-ring are chemical-resistant, and the grease-free collet and chuck mechanism allows use with steam in a wash down environment. It is suitable for use with nylon, polyurethane, and polyolefin tubing at a maximum operating pressure of 145 pounds per square inch (psi), a maximum operating vacuum of -100 kilopascals (kPa), and an operating temperature range of -5 to +150 degrees C. This KQG2 series push-to-connect bulkhead union tube fitting is Restriction of Hazardous Substances (RoHS) compliant and is suitable for use with air, water, and steam in both vacuum and pressure applications, such as food processing in a wash down environment.
Tube fittings are components used for connecting, branching, terminating, and changing the direction of tubing in pneumatic and hydraulic systems. They are made of brass, stainless steel, polybutylene terephthalate (PBT), and other materials that resist corrosion and wear. Tube fittings have various types of connections, including threaded, welded, barbed, and push-to-connect (also called one-touch). Push-to-connect connections do not require tools or sealants. Tube fittings are used in various applications, including machine tools, airplane and truck controls, and automated production lines, among others.
