Push-Fit Adapter for Air and Water Lines
The SMC KQ2H04-M6A is a brass push-fit adapter fitting designed for pneumatic and non-potable water applications. It connects a 4 mm outer-diameter tube on the push-to-connect side to an M6x1.0 male metric thread on the other side. The fitting handles a maximum operating pressure of 145 psi and a maximum operating temperature of 140 degrees F. It is supplied new and ready for installation in compatible fluid systems.
Suited for Compact Metric Thread Ports
This adapter suits engineers and technicians who need a quick, tool-free connection to a small M6x1.0 port in air or non-potable water circuits. The push-to-connect end accepts 4 mm tubing without additional clamps or soldering. It is not intended for potable water systems, high-pressure hydraulic lines exceeding 145 psi, or applications requiring a larger tube diameter or a different thread standard such as BSP or NPT.
Consistent Seal Under Continuous Pressure
Under sustained load the brass body and pre-applied thread sealant maintain a reliable seal at the rated 145 psi limit. The push-to-connect mechanism grips the 4 mm tube securely during prolonged pressurisation and thermal cycling up to 140 degrees F. Performance remains stable without the pressure drop or leakage spikes sometimes seen in short-term burst tests.
