Aqua Marina Laxo kayak deflation valve

thingiverse

Aqua Marina Laxo kayak comes with a deflation mode on a pump, but there is no way to attach it to the kayak as existing boston valve prevents deflation. This is a copy of existing boston valve without the rubber valve part, which allows the boat to be deflated using the provided pump. A 20-22mm internal diameter, 3mm thickness o-ring is needed for best performance. Alternatively cut a rubber ring of ID ~20-22mm, OD - ~28-32mm
