Fittings are required to connect hard tubes to the desired components. Our SK-HTF fitting has a non-slip surface that makes assembly easier.
First, the union nut is unscrewed together with the O-ring inside. The connection can then be screwed to any component with a G1/4" thread. The union nut is first pushed onto the deburred HardTube and then the remaining O-ring is pushed on. The HardTube is then pushed into the fitting as far as it will go. The last step is to screw the union nut onto the connection. It is important to ensure that the rubber seal rests cleanly on the connection in order to be able to seal properly.
