The RS-510 regulator is the latest TUSA first and second stage that delivers excellent quality in an affordable, lightweight, travel-friendly system.

The balanced piston R-500 first stage is incredibly small and weighs only 720g. It has a full complement of four low-pressure and two high-pressure ports and is equipped with a quick adjustment screw that can easily be tuned for optimum performance.

The S-10 is a lightweight, easy-breathing, dependable second stage equipped with TUSA's ortho-friendly mouthpiece for greater comfort and reduced jaw fatigue.

New Ortho-consciously designed mouthpiece
The new mouthpiece further enhances the comfort of bite, fit, and stability. Even with a light bite, a high level of stability is achieved so there is no fatigue from long periods of usage.

Breathing resistance adjustment knob
With the S-70 you simply rotate the flow adjustment knob on the side with its ideal click feeling for free control of the air supply volume according to your needs. The multiple thread screws permit speedy and fine adjustment from which you can appropriately sense resistance to exhaled air to a condition in which you feel almost no resistance.

Universal Swivel Hose
For optimum performance and comfort, a swivel hose is fitted between the S-70 second stage and the R-600 first stage. The swivel joint allows flexibility of the hose to eliminate hose tension at the mouthpiece for a more natural and comfortable bite.
