The new pressure relief valve has to be inserted between the inflatable boat and the air source , inflator , electric inflator or air-compressor. When overtaking the best pressure the valve releases the surplus air . It replaces the pressure-gauce.
When the inflatable boat is too inflated , through inserting the pressure relief valve into the inflation/deflation valve , the surplus air will be released leading the inflatable boat at its best pressure .
It could be fit to all inflators and to the main valves that are in the market.
