Helmet/Mask Bag
Measurements: 16’’ length x 12’’ width x 16’’ height. Made of high quality, tough black nylon, encasing a lightweight, white polyethylene foam that features low water absorption and is fairly rigid (good impact strength). The two grommeted ventilation holes seen in the photo are on both sides of the bag. A large elastic topped pocket is on each side, for holding tool kits, checklists, logbooks, spares, etc. (There are no inside pockets). The bag handles are 1” wide straps of black polyester webbing. The bag closes up with two, large YKK zippers. We do not recommend the 500-901 helmet bag as a shipping container or packaging for your Kirby Morgan life support equipment!

Restrictor Adapter
The 555-210 Restrictor Adapter should be used when an inflation hose is attached to the side block when drysuit diving. The main purpose of the Restrictor Adapter is to limit gas flow in the event the hose ruptures or is severed, and to ensure the loss of supply would not be great enough to significantly affect the diver’s breathing at moderate to heavy work rates. It also helps prevent filling the dry suit too rapidly.   NOTE: O-ring 310-003 is required to install the Restrictor Adaptor onto the side block.
