Automatic Venting Cap (W772)

Automatic Venting Cap(W772):

This is one of the few fittings that we do not make in house but still approve for use with FatSac brand sacs. The Automatic Venting Cap is primarily for use in automated ballast systems that are plumbed into the boat aftermarket. You can screw this fitting into the valve at the top of your sac and it will allow any air trapped inside to escape while remaining watertight. Made from 6/6 Nylon with a proprietary Heyco membrane inside.

• This fitting allows the air to bleed from the bag, but not water.
