The practice of installing a dry suit inflation whip with modified fittings onto a KM 37 side block has been reported to IMCA.
Kirby Morgan Dive Systems Inc. has advised the following:
♦ The modification to the side block assembly shown in the photograph above, is not recommended
♦ The leverage on the brass fitting is extremely high giving a high potential for breakage
♦ The fitting at the bottom of the side block is a 3/8" straight thread fitting with an O-ring seal which is not designed to sustain this kind of leverage
An in-line valve is not deemed necessary, as long as a good quality and suitably approved inflator hose or the KMDSI restrictor adapter Part Number 555-210 is used.
