Hi Flow Air Inlet Swivel
The high-flow swivel allows the regulator hose to move freely and align with the mask without putting stress on the hose coupling. It uses standard SCUBA threads for incoming breathing air.
Manifold Block
The Manifold Block Assembly provides a control point for your bailout supply when using a light weight full face mask like the EXO® Mask. It is equipped with four low pressure outlets and a check valve. It is available with a 9/16" O2 fitting or a #6 JIC fitting, or a standard SCUBA fitting.
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.
