The XS Scuba 110 Degree Adapter (AC911) is designed to improve regulator comfort by changing the angle of your second-stage low-pressure hose. Installed between the regulator hose and second stage, it routes the hose under the arm for a more natural position, helping reduce jaw fatigue and hose pull during dives. Constructed from durable chrome-plated brass with Viton® O-rings, the adapter is factory cleaned and suitable for low-pressure regulator systems operating below 200 psi. It is also compatible with Nitrox up to 40% oxygen.
