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.
