Body and Insert quick seal coupling for both the USWE Hand-free kit and the Elite, Shape-Shifter and Disposible hydration bladders (when you want to provide a quick and spill-proof removal of drink tube allowing you to refill your hydration bladder without rerouting your drink tube through your hydration pack). ATTENTION For best function and durability the body and Insert couplings will need some love (cleaning) after each use. Always make sure that the o-ring is wet before connecting the Body and Insert. SPECIFICATIONS Outside diameter 7,5mm Includes both body and insert coupling
