EXO Full Face Mask Manual
1.4.4 Low Pressure High Flow Hose
A low pressure high flow hose for the EXO-26
or EXO-BR is available. This hose will deliver
the maximum amount of air to the regulator.
Order DSI Part #: 255-050, LP High Flow Hose.
1.4.5 Manifold Block
If you use the EXO for
surface supplied div-
ing, a manifold block
which has a one way
valve and provides for
correct attachment of the
umbilical is essential. The
emergency valve on the manifold block also
controls the flow of the bailout supply.

1.4.8 Face Cushion Kit
A face cushion kit for the EXO-26 and EXO-
BR is available. While the majority of owners
find the mask provides a watertight seal right
out of the box, some divers with small or nar-
row faces may experience trouble getting a com-
fortable, tight seal. This optional cushion is de-
signed to give divers with smaller faces a better
seal. It is easily installed to the interior of the
mask. Two velcro tabs secure the cushion in-
side the seal, with the ends of the cushion slipped
into the earphone pockets.

1.4.7 Regulator Mount Nut Tools
These tools are used for removing and replacing the regulator assembly. The mount nut tool
works on the newer EXO-Standard and EXO-BR as well as the EXO-26's with the original style
regulator mount nuts. These tools are required if an entire regulator rebuild or face seal replace-
ment is to be attempted.
These two procedures, entire regulator rebuild and face seal replace-
ment, can be difficult. DSI recommends that these two procedures be done by a factory
trained DSI dealer. If you are unsure if your local dealer is qualified to do this repair, call
DSI for the nearest qualified dealer in your area.
