A regulator for diving controls the level of the diver's breath gas. While this is typically the case, regulators are also capable of controlling pressures for other gases. The second stage of a regulator for diving can be called the alternate stage. Attached to the tank of the diver is the regulator cylinder. The diver will breathe through it to keep him comfortable underwater.
Scuba regulators
Scuba regulators form an integral part to a scuba divers system. They regulate how much air is delivered to the diver to allow them to breathe easily and comfortably. They can also stop or start air delivery below water. A purge button on the regulator allows the diver to empty the water chamber and let out a stream of oxygen if necessary.

Alternate stage
The primary stage and the second stage are the two main parts of a regulator for divers. The primary stage is responsible for providing air to the diver, and the secondary stage is used to replenish that air. The alternative stage can either be a less-efficient or better performing model. It is not as effective as the primary stage, but can perform the exact same function.
Balanced regulator
The Balanced regulator is a versatile, efficient scuba diving regulator that provides breathing gas to divers with minimal effort. Its innovative design and superior materials make it an excellent choice in any diving environment.
DIN valves
The type of valve is an important feature to consider when choosing a dive regulator. Two types are most common: DIN and Yoke valves. An O-ring on a Yoke Valve fits into a threaded fitting on the tank’s valve. A DIN valve, on the other hand, has an o-ring that fits into a threaded connection on the regulator's first stage.
Swivel joint hose adaptor
Divers can use a swivel joint adaptor for their dive regulator as a versatile accessory. This allows you to route regulator hoses in a natural manner and reduces jaw tension. This accessory allows you to share your air with your buddy. These accessories can be used in a few seconds and should be washed off after each dive.

Environmentally sealed regulators
There are many choices when it comes to choosing an environmentally sealed dive regulator. These regulators have many benefits, making them a great choice for people who like to dive in cold waters. They are corrosion-resistant, and can be made from zirconium rather than brass. Many of these products have an integrated environmental seal and a large button for purging. Some products even have a limited lifetime warranty.
