Weighing in at a tiny 905g (DIN version), the XL4 First Stage is the lightest ever cold-water regulator produced by Apeks. Light on weight doesn’t mean light on features though. This compact regulator includes Apeks' latest cold-water innovation, an over-moulded first stage endcap that reduces ice build-up around the First Stage. This technology greatly reduces the risk of a free flow in low temperatures. Cold water performance is further improved by heat exchangers on the First Stage (as well as the XL4 Second Stage).

Ideal for technical divers looking to reduce the weight of their setup, the XL4 can also be used as a neat and compact regulator for stage cylinders, perfect for the technical exploration diver with a large amount of equipment.

The XL4 is a high-performance option for divers serious about weight savings.

Features and Benefits

  • Compact machined First Stage based on the expedition tested Apeks DS4 platform.
  • Break through, innovative over moulded first stage endcap & 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 the First Stage, resulting in improved cold water performance.
  • Unique over balanced diaphragm design as the diver descends, the over balancing feature allows the medium pressure gas in the hose to increase at a faster rate than ambient. This results in superior performance at depth.
