The Envoy II first stage regulator features an internal structure that enables direct airflow, providing remarkable performance. Its conical precision stainless steel high-pressure valve and advanced polymer seat ensure enhanced reliability, service life, and responsiveness at all breathing rates. The balanced diaphragm design offers years of corrosion-free service with high-performance porting. The chrome-plated marine brass first stage regulator boasts a balanced diaphragm design, inherently environmentally sealed. This protects delicate internal parts from contaminants like salt, sand, chlorine, and pool acids that can cause corrosion and mineral deposits, affecting performance. The first stage regulator houses 5 low-pressure (LP) ports with 3/8"-24 UNF thread and 2 high-pressure (HP) ports with 7/16"-20 UNF thread. The lightweight, compact, and comfortable Envoy Second Stage features a Venturi (Free-Flow) control. Over time, evolutionary design changes have resulted in a regulator that resists free-flow on the surface while offering incredible smoothness and ease of breathing underwater. This pneumatically balanced downstream demand valve second stage regulator is made from brass, flexible and rigid thermoplastics, elastomeric polymers, and silicone rubber. The standard hose measures 30" (76cm) and has 3/8" threading. Weighing 3.22 lbs.
