Additional specifications

The Apeks XL4+ Stage 3 Regulator Set Yoke is especially well-suited for the technical exploration diver who prefers cold water climates. Compact and lightweight, it helps reduce jaw fatigue during long, cold dives. Designed with an innovative, over-moulded endcap in conjunction with the environmental diaphragm that helps prevent ice build-up.

1st Stage Features

Breakthrough, innovative over-moulded first-stage endcap and 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 Features

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
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
Durable and flexible rubber exhaust tee provides excellent bubble diversion.

XL4+ Octopus

DOUBLE SWIVEL HOSE - Reduces tension on both ends of the hose to improve overall comfort.
VENTURI LEVER - Disrupts the airflow inside the 2nd stage to prevent accidental freelows at the surface.
