How to Connect a Buoyancy Compensator Hose to a Scuba Tank

A scuba system is made up of several components.

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.

Things You'll Need

• Allen key
• Low-pressure inflation hose
• Scuba regulator first stage
• Adjustable wrench

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.
