Mares XR 25XR First Stage Right

Mares XR 25XR First Stage

The 25XR first stage was primarily designed to meet the needs of divers using a twin tank setup or for stage mounting. The LP and HP ports are positioned on one side and are pre-oriented. The kit includes one right 25XR first stage and one left 25XR first stage.

The hose outlets are arranged so that they are oriented downward during assembly. This feature makes it ideal for cave diving or environments with restricted passages.

Thanks to the T.B.P. anti-freeze kit, the first stage is perfectly sealed, ensuring high performance even when diving in cold water. It also prevents the entry of sand or particles, especially when diving in caves or contaminated waters. The reliability of this first stage is further enhanced by the A.S.T. (Auto Sealing Technology) system, which keeps the first stage clean and dry at all times and is tested with oxygen, at low temperatures, and under high airflow conditions.

The main features of the 25XR first stage are:

• Solid, compact one-piece body
• 2 LP ports (3/8" UNF), all angled downward
• 1 HP port (7/16" UNF) with interchangeable port design (IPD)
• Perfect LP hose positioning, ideal to prevent entanglement
• DFC – Dynamic Flow Control
• T.B.P. dry kit: sealed for improved performance in cold water dives. Prevents ice buildup and the entry of sediment and contaminants into the system
• Designed for use with twin tanks, but also suitable for single tank or stage configurations
• Twin configuration: compliant with all training agencies, from RSTC divers to DIR standards, and suitable for all XR applications, including cave diving
• Minimizes the risk of accidental snagging, with no hose elbows and easy access to manifold valves
• AST – Auto Sealing Technology (anti-infiltration technology):
  • Keeps the first stage dry and clean. Uncompromised reliability
  • The system activates automatically with air
  • Tested with oxygen at low temperatures and in demanding environments
  • Patented system
• G5/8 connection, 300 bar (DIN)
