Scuba Regulators & Scuba Regulator Sets

Reliable scuba regulators are essential for safe and comfortable underwater breathing. Whether you're a beginner or an experienced diver, choosing the right scuba regulator set ensures smooth airflow and effortless breathing at any depth. We carry regulators and regulator packages from the top brands in the industry, and our packages include everything you need to get started.

Scuba diving regulators are an essential component of your diving equipment, acting as the lifeline between you and your air source underwater. The regulator connects to your dive tank, and together, they make up a self-contained breathing apparatus that allows you to breathe comfortably while diving. The compressed air inside scuba tanks is stored at extremely high pressures, which could cause injury if breathed directly from the tank. Your regulator reduces the pressure of the compressed air to make breathing underwater possible.

At Scuba.com, we offer a wide selection of scuba diving regulators designed for performance and durability in various diving conditions. From balanced and unbalanced models to cold-water and high-performance options, our regulators provide a secure and efficient air supply for every dive. Ensure your safety and shop for scuba regulators at Scuba.com today.

Breathe Easy with a Reliable Scuba Diving Regulator

Scuba diving is all about being able to stay underwater—and at greater depths—for prolonged periods. You’ll need a lot of breathable air to last long when you take a dip, but storing it in its basic form won’t help you maximize your enjoyment during your next dive as bringing air underwater entails pressurizing and compressing it into a cylinder tank.

Diving regulators are an innovative invention that reduces the high-pressure air stored inside tanks, which divers can inhale through a connected mouthpiece. It is composed of a first stage scuba regulator and a second stage regulator that work hand-in-hand to deliver breathable air from your tank to help you breathe while diving. Your regulator functions as the central hub of your dive equipment, connecting your tank, gauge, and buoyancy compensator.

Purchase a Scuba Regulator at Scuba for a Stress-free Dive

Breathing underwater is a thrilling experience, especially if it’s your first time taking the plunge. That’s why you’ll need a reliable dive regulator so that you can breathe easily during your underwater excursions.

The first step to choosing a regulator involves figuring out what kind of diver you are, the diving you plan to do, and the environment you plan to dive in. And you won’t have to look far to find a cheap scuba regulator that doesn’t compromise performance. If you plan to plunge deeper and in colder temperatures below 10°C, you’ll need a high-performance regulator that can withstand extreme conditions. Once you’ve narrowed down your top choices, hook them to a tank and check if you can breathe easily. Pay attention to the mouthpiece fit as well.

Scuba carries various scuba regulators for sale including first stage and second stage regulators. You can also find a scuba regulator set that includes first and second regulators in our inventory. We carry products from the leading brands, including Aqualung, Atomic, Mares, and Scubapro. Our top-quality regulators will give you peace of mind knowing you’ll have a steady supply of air underwater. Shop for the best scuba regulators here.

How do Scuba Regulators Work?

Scuba regulators generally work in two separate stages. The first stage takes the highly compressed breathing gas from your tank and reduces the compression to an intermediate stage. The second-stage regulator fits into your mouth to deliver breathable gas as you dive. It takes the intermediate pressurized air and reduces it to a pressure that’s safe to breathe.

What is a Balanced, Unbalanced, and Overbalanced Scuba Regulator?

A balanced regulator can supply consistent airflow no matter how deep you’re diving or how much pressure there is in your tank. Balanced regulators make it easy to breathe throughout your dive in any environment.

Unbalanced regulators feature a simpler design, but they’re harder to draw air from as the tank pressure decreases or depth increases. Overbalanced regulators increase air flow as depth increases.

How Often Should I Service my Scuba Regulator?

Even if your equipment seems to be functioning properly, you should always have your scuba regulator serviced once a year or every 100 dives, whichever comes first. After all, it’s your lifeline while diving.

You should also have your regulator inspected and serviced if it shows any inconsistencies, problems, or accidents. Between uses, make sure to properly store your regulator to prolong its life.

Do I Need Scuba Regulator Accessories?

Your scuba regulator should come with all the components you need for safe and successful operation, but it’s always a smart idea to stock up on a few key accessories including replacement mouthpieces, hoses, valves, purge covers, and o-rings. They’re compact and easy to store, so you can swap them out on the dive boat between dives.

How do I Clean my Scuba Regulator?

Always rinse your regulator with clean, warm, and fresh water after a day of diving to remove salt and minerals. Wash the dust cap and then make sure it’s completely dry before reattaching it to your first stage. You can soak your second stage in warm water for a few hours, but you should never soak the first stage or press the purge button while cleaning.
