The design of the underwater breathing tube is very reasonable, using multiple structural designs, a fully dry intake valve to promote smooth breathing, and a food grade silicone hose to further improve safety during use.
The underwater breathing tube adopts a rapid water stop system, a floating ball type automatic drainage valve, immersion and closure to prevent water choking.
The underwater breathing tube adopts a face lens with a connecting buckle, which is thick and durable, and can be operated with one hand, simple and fast. It automatically locks when pressed, and unlocks when squeezed inward on both sides.
The underwater breathing tube adopts ergonomic comfortable bite, food grade silicone does not produce odors, is safe and non-toxic, and the hose adopts tracheal structure to keep the trachea soft and unobstructed.
The underwater breathing tube uses a single bottom check valve with a lower head, which facilitates the discharge of accumulated water from the breathing tube and prevents backflow due to water ingress.
Adjustment and wearing methods:
The assembly method of the mask is to first place the breathing tube on the left side of the headband and fix it with a tube buckle (quick buckle). While adjusting the headband, please adjust the position of the tube and rubber ring (tube buckle) up and down until you can easily bite your mouth. The basic position of the breathing tube is usually near the front of the left ear. Gently press your teeth against the protruding part (tooth groove) of your bite, then gently wrap your lips around it. If you bite too hard, it may break the protruding part of the biting mouth. Please be careful with the pipe buckle rubber ring.
Breathing tube drainage: Exhale the residual air in the lungs with force and expel the accumulated water in the breathing tube. If there is still some water accumulation in the pipe at this time, it is necessary to slowly inhale and then repeatedly blow air until the water is completely drained.
