Duotight connector removal tool

I bought some Duotight quick disconnects but removing the tubing from the fitting is difficult if you want to redo the connection or replace the tubing. This tool slides over the tubing and can be used one-handed to apply pressure to the lock collar and release the tubing. The design is similar to a Sharkbite plumbing removal tool.

NOTE: this fits 5/16" OD tubing (8mm)
