Manifold port blank, or cover, for Interspiro's Divator, MkII mask assembly (Item 20, on the attached drawing)

All Divator plastic parts are made in GRP (Aramide 12) for strength, stability and wear properties.

This blanking piece locks the demand valve to the mask and it may be relaced with a variety of customised communication and speech devices.

It comes fitted with O-seal and thumb screws, fro easy fitting and release. Lubricate the O-seal and screws with a little silicone lubricant - such as Dow Corning S4; for ease of fitting and to prevent corrosion to the screws and their receieving, threaded, brass inserts.

Tools needed: None.
