 Regulators, BCs, Octopuses, why so many hoses?








The first time you go for your scuba dive, it is very easy to be overwhelmed by all the different hoses that are surrounding your dive suit. These hoses and their components, which include your regulator , mouthpiece, an alternate air source, a submersible pressure gauge, and a low-pressure inflator.

Before we get into how these components work together, let's talk about them separately and what each gear is supposed to do. The purpose of your  regulator and its mouthpiece is to deliver the air from your tank to your lungs at just the right pressure. An alternate air supply will allow your buddy to breath from your regulator if he runs out of air supply or his regulator malfunctions. A submersible pressure gauge will tell you how much air is left in your tank, whereas a low pressure inflator will allow you to add  air from your tank to your BC.

Typically, all the hoses are attached to a port that is built into the first stage. The first stage, is the hose that connects the tank to the regulator. If there are not enough ports built into the first stage, then consider purchasing a port adapter(similar to an adapter that allows you to plug in multiple appliances) to it.  

High pressure ports are used for equipment like the submersible pressure gauge, whereas low pressure ports are used for items like the second-stage hoses, low-pressure inflator, and the dry-suit inflator.
