The Ozone version of the Boston valve and has a middle red section that contains the seals and these sometime perish or fail over time or sand gets in and damages the plastic and you need to replace it. It also now comes with top cap too as a spare part.
This is a simple replacement part for the ozone kites and should work fine for most other kites or items with a Boston valve but we can't guarantee it will fit other Boston valves we only know it works 100% on the ozone ones but you could try?
