Now redesigned for use with a standard 3/8-inch LP regulator hose. The OP valve is now located in the first stage, freeing divers to switch hoses easily without ordering a Jetstream-specific hose.

Selected by the US Navy and NASA due to its simple construction, high performance and ease of breathing at any depth. The Xtream first stage uses a patented spherical stainless steel ball along with a soft seat material that virtually eliminates high pressure seat wear that is common in “knife edge” design seating systems. The Xtream first stage also uses a rolling diaphragm design that eliminates any restriction in movement, which creates a smooth transfer of gas from the first stage to the second stage. This rolling diaphragm design effectively creates a polymeric barrier insulating the diaphragm and gas volume so there is no need for additional environmental kits. The Jetstream second stage uses servo valve technology that seals the seat without the use of conventional knife edge sealing. This allows for very low inhalation effort to open the valve. The servo valve design also eliminates any need for a Venturi or adjustment knob. As the world’s premier side breather the Jetstream offers incredibly easy breathing at all depths and guarantees you enough air regardless of workload. The Jetstream can be worn on either the left or right side, making it ideal for sidemount diving. The Jetstream first stage is equipped with a safety valve in case a high-pressure airflow should occur. This safety valve prevents the air stream from flowing out through the mouthpiece straight into your mouth as conventional downstream regulators. This construction will instead release the flowing air out into the water directly from the first stage. CE EN250 approved.
