This is a custom made upgrade for the APD Inspiration and Evolution re-breather DSV mouth piece. This replacement screw will make the opening and closing of the DSV much easier by allowing almost one handed operation. Well one hand, one finger!
A number of people are now using this with excellent results, so now I am offering this to others It is made from 316ss (A4) stainless steel with a very high quality finish and a knurled end for easy fitting and grip.
It only takes 30 seconds to fit.
Please note this is for the screw only not the complete DSV
