How to Connect a Buoyancy Compensator Hose to a Scuba Tank

Buoyancy compensator devices allow a diver to adjust how buoyant they are under the water and on the surface. They are connected to a scuba tank via a low-pressure hose which runs to a scuba regulator first stage, which is attached to the tank. You should ensure that all connections are functioning before you go diving, to prevent leaks or non-functioning of the buoyancy compensator device.

Instructions

    • 1

      Remove the cover from the low-pressure port on the regulator first stage with an Allen key.

    • 2

      Screw the threaded end of the low-pressure inflating hose onto the low-pressure port of the regulator first stage. Tighten it with an adjustable wrench.

    • 3

      Attach the buoyancy compensator device strap to the tank and pull it tight.

    • 4

      Match the regulator port to the matching port on the scuba tank valve. Fit the connection together and tighten the handle until it is "finger-tight."

    • 5

      Pull back the guard on the end of the low-pressure inflating hose. Push the end of the hose onto the inflating valve of the buoyancy compensator device. Release the guard so that it snaps into place.

    • 6

      Open the valve handle on the scuba tank by turning it counterclockwise to release air into the system.
