Made from brass, the tool is handy for installing LP and HP O-rings onto hoses or port plugs by simply capping the tool on top of the equipment and sliding the o-ring on.

Easy installation of the o-rings is now possible without damaging the o-rings on the threads.

The tool is also suitable to install the o-ring inside the recessed groove of the LP hose near the second stage end.

Hose or port plug are not included.
