Si Tech inflation/manual add valve tool

thingiverse

This tool is designed to help remove Si Tech Inflation Valve from a drysuit or rebreather counterlung. The inner notches line up with the two notches on both the front and backside of the valve and the outer notches provide a gripping surface. The tool is open at one end so that it can be inserted, if necessary, through the T-Piece hole into a rebreather counterlung to hold the backside of the valve while unscrewing the front. This is version 2, which is slightly improved. The first version had a an exterior notch for gripping that was in the middle of the "horseshoe" which made it prone to stress fractures. That has been removed. Recommend that you print with a relatively high infill % for strength.
