Union Straight

Union straights are a type of pneumatic fitting that allow for tubing of the same size to be connected together.

Push-In Fitting Usage

With Push-In fittings, simply place your tubing into the tube end of the fitting, and lock jaws will engage to. A gentle tug will ensure that your tubing is locked into place, rendering it suitable for high pressure usage in pneumatic systems.

To disconnect the tubing, push the release ring. This disengages the lock jaws, and the tubing is able to move freely.
