This specially designed C-spanner is made to fit popular models of Scubapro first stage regulator such as MK2, MK5, MK10 and MK25. (For the MK11 and MK17 we recommend our designated tools).

Made from heavy-duty but lightweight aluminium, the diameter has been carefully chosen to give the best fit on the cap and diaphragm clamp in a variety of models.

Regulators are not included.
