Diving Regulator

This page is to familiarize divers with their diving regulator, tips when buying one and how to maintened.

The primary function of the diving regulator is to reduce the compressed air from the cylinder to an ambient pressure and automatically activate the demand valves when divers inhale and exhale; giving them just the air they need for each inhalation. In diving helmets, the airflow is constant making the modern regulator the perfect choice for divers.

Diving Regulators Consisted

  • First Stage: Reduce the compressed air from the cylinder to an ambient pressure.
  • Second Stage: That consist in a primary regulator and secondary regulator or OCTOPUS, and activate valves when divers inhale and exhale.
  • Low Pressure Inflater Hose: That is connected to the BCD to control your buoyancy.
  • High Pressure Hose: with Console at the end, to monitor your air on the tank and depth.

When Buying A Regulator

TIP # 1: Make sure your dive shop is an authorized dealer for servicing and repairing your regulator's brand choice.

TIP #2: Check if in your dive area they use in the tank a yoke valve with an o-ring; which is by far the most common style in use; or DIN valve that is typically used with high-pressure steel tanks. You also can have an adapter.

TIP #3: A Nitrox-compatible regulator requires a Nitrox-compatible octopus or alternate.

TIP # 4: Your regulator's mouthpieces needs to feel comfortable in your mouth. If your mouth and jaws are sore after a dive, the mouthpiece might not be a good fit for you.

TIP # 5: In the console of the regulator you can have a pressure gage (BARs or PSIs), Deep gage (Meters or Feet) or replace both by a diving computer. You also can add a compass to the console.

Tip # 6: Buy your regulator as a package or complete with all 4 hoses (primary second stage, alternate second stage, flow pressure hose and high pressure hose with console).

Make it a habit to always perform a check on all your equipment before a dive.


If you find some leaks on your regulator's second stage, most of the time it's sand residue, so rinse with fresh water. If o-ring does not seal properly; release the pressure check if o-ring is lubricated and move the hose around a little bit. If any of the suggestions above do not work we recommend that a professional take a look on your regulator.

After the dive and removing your regulator from the tank, you must cover the first stage immediately and then clean the regulator in fresh water; removing all the salt, dirt and sediments like sand; then dry your equipment out of direct sunlight.

Check hoses and look for cracks, worn areas, and bends or bulges. If you find what looks like a potential problem, replace the hose. And never fold your hoses too tight when you store your regulator.
