Scuba diving regulators are made up of different elements, including 1st stage regulators. A 1st stage regulator attaches directly to your cylinder and reduces the air pressure down to an intermediate level. Your 1st stage regulator will connect via hose to a 2nd stage that allows you to breathe.

At Aquanauts, we stock a great range of 1st stage regulators, with different products available to suit varying diving needs. Whether you are recreationally diving or deep diving, the 1st stages we stock will have you make a perfect upgrade or replacement.

If you need any advice when it comes to buying the right 1st stage regulator, or want to buy your regulator as a full set with 2nd stage and your octopus, speak to our scuba diving experts who will be able to help you find the right products for your needs.
