The size of this thin spanner is 19 mm with both open and close-ended sides. The thin size of the wrench is ideal for the removal and installation of Suunto transmitter which is sometimes difficult with a conventional 19 mm spanner. The wrench is also suitable for the heat exchanger of Aqualung Legend 3 second stage.

There is also a 3/8" drive for use in conjunction with a torque wrench if required.

We recommend to use:

• the open ended side to hold the nuts/heat exchangers in place during hose removal and installation
• the open ended side to torque the nuts/heat exchangers 
• the closed hex side to remove and install the nuts/heat exchangers

Since this tool acts as a torque adapter/multiplier, please check out the "use of torque adapters".

Made from Aluminium 6061 with anodized finish.

Regulator and additional tools are not included.
