The SMC PNEUMATICS KQ2W11-37AS is a push-to-connect tube fitting in an extended male elbow configuration, designed for quick, tool-free tube connections in pneumatic and fluid-handling systems. Built from brass with a polybutylene tube collet, this fitting accepts 3/8 inch OD tubing and connects to 1/2 inch NPT threaded ports. It carries a maximum working pressure rating of 145 psi, making it suitable for a wide range of compressed air and compatible fluid lines. Technicians in industrial, HVAC, and mechanical systems work use this fitting to route tubing around obstacles or change direction at a threaded port without additional adapters.
This extended male elbow fitting is well suited for pneumatic control systems, compressed air distribution lines, and inline plumbing connections where a 90-degree direction change is required at an NPT port. The extended male thread configuration provides additional clearance when fitting into recessed or tight manifold ports. Compatible with 3/8 inch OD polybutylene or similarly rated flexible tubing. Operating temperature range is 23 degrees F to 140 degrees F, which covers standard indoor industrial and mechanical room environments.
Designed for use with 3/8 inch OD tubing in systems with 1/2 inch NPT threaded ports, typical of pneumatic control circuits and compressed air distribution assemblies.
This fitting is installed by licensed pipefitters, pneumatic system technicians, or qualified mechanical trades. Depressurize and isolate the system completely before removing or installing any pneumatic fittings. Ensure the NPT threads are clean and apply appropriate thread sealant per system requirements before torquing the fitting into the port. When inserting tubing, push firmly until the tube bottoms out in the fitting body; to release, depress the collet release ring and pull the tube straight out.
