Brand: Apeks

Model: XL4+ Regulator

SKU: 77373-1

Please note: This item cannot be shipped outside the European Union - learn more

The Apeks XL4+ Regulator is a white version of the popular, compact, cold water XL4 Regulator. With one small adjustment, a second HP Port, the XL4 Plus is more practical for divers who want to use an analogue gauge and a wireless transmitter.

Who is the XL4+ For?

The XL4 + is tested for cold water while keeping lightweight for travelling divers. A small 2nd stage is perfect for longer dives to reduce jaw fatigue and reduce bulk on a stage cylinder.  The XL4+ is perfect for divers who want a regulator they can use in cold waters that isn't heavy so they can use it as a holiday regulator too.


Any Apeks Octo is compatible with the XL4+ but the XL4 Octo is best if you're looking to build a single cylinder setup. Any LP Inflator Hose will fit the XL4 and Apeks' Tech Gauge and Hose is the perfect SPG for a single cylinder set.

Recommended Accessories

For Single Cylinder Setups:

For Stage Cylinder Setups:


Prescription Lenses

1st Stage

  • Compact machined 1st 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 1st 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.


2nd Stage

  • Compact and lightweight 2nd stage improves comfort and helps reduce jaw fatigue on long duration dives.
  • High performance pneumatically balanced lever operated poppet valve.
  • Large, over moulded self-flushing and controllable purge button.
  • Ergonomic Venturi lever is easy to use and locate.
  • White flexible nylon braided hose has better cold water performance than 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.
  • UV inhibitors to help prevent discolouration of the white materials.
