Product Overview

The Apeks XL4 is a compact, lightweight regulator suitable for diving in all environments including cold water locations. Its design and low weight help reduce jaw fatigue on long dives. The XL4 also makes an ideal stage regulator, perfect for the technical exploration diver with a large amount of equipment. The XL4 is a high-performance option for those technical divers serious about weight savings. Compact machined first stage based on the expedition tested Apeks DS4 platform (see SKU: APXATX40).

Break through, innovative over-molded first-stage endcapand environmental diaphragm helps prevent ice build-up that can cause first stage free flow in extreme circumstances. Also protects the first stage from impact damage. Large surface area heat exchanger diaphragm clamp helps increase the gas temperature inside thefirst stage, resulting in improved cold-water performance. Unique over-balanced diaphragm design f as the diver descends, the over-balancing feature allows the intermediate pressure gas in the hose to increase at a faster rate than ambient. This results in superior performance at depth. First stage has four 3/8" UNF threaded low-pressure and one 7/16" UNF high-pressure ports.

Compact and lightweightsecond stage improves comfort and helps reduce jaw fatigue on long duration dives. High performance pneumatically balanced lever operated poppet valve. Large, over molded self-flushing and controllable purge button. Ergonomic Venturi lever is easy to use and locate. Flexible nylon braided hose has better cold-water performance than a traditional rubber hose. Standard metallic hose connection for interchangeability. Comfo-bite mouthpiece has a unique bridge that fits across the upper palate and does not require bite pressure to stay in place. Re-useable mouthpiece clip makes it simple to change mouthpieces in the field. Durable and flexible rubber exhaust tee provides excellent bubble diversion. 2'nd stage can be configured for right or left-hand use. Regulator is Nitrox compatible to 40% O2 when new, out of the box and can be O2 cleaned to 100%. Comes with an owner's manual.
