The inflator hose and dump valve’s cut outs in the outer shell are urethane protected from fraying. The circular air cell design eliminates the chance of gas being trapped thus providing technical divers with precise buoyancy control any time during a dive mission.The JT-50 is strictly designed for twin tank use only.
