Poseidon Service Parts

Poseidon part 4828 is the dedicated first-stage service kit for compatible 90-degree Xstream Duration and Oxygen configurations that use the M26x2 / EN 144-3 connection. It packages the model-specific wear parts and seals used during a scheduled overhaul; it is not a universal Xstream kit and it is not a complete regulator.

• Poseidon service-kit part number: 4828
• Documented for Xstream Duration90 / Oxygen 90 first stages with M26x2 connection
• Genuine model-specific service components

Technician-only service: Poseidon regulator work must be completed by a trained, certified technician using the correct service manual, oxygen-clean procedures where required, specified lubricants, torque values, and final pressure and breathing-performance tests. Match the first-stage article number and serial-number requirements before ordering; do not select a kit by appearance alone.
