Upgrade for SuperLite-27 Owners.
SuperLite-27, equipped with the Tri-Valve Assembly, P/N 525-755, Kirby Morgan Dive Systems, Inc. This upgrade is a replacement for the old style Water Purge Deflector (pre-November 2005). The new Water Purge Deflector, P/N 505-726, now is equipped with a valve and valve cage assembly. This will help to keep your helmet dry inside and helps to prevent any backflow of water into the helmet.

If you purchased a Tri Valve Kit (P/N 525-755), or a SuperLite 27 with Tri Valve, prior to November 2005, your helmet may not be equipped with this upgrade.

Contact your local Kirby Morgan dealer for a replacement if your helmet has the Tri Valve, but is not equipped with this current model.
