The MK5i Cartridge UMA 5000 is for re-arming auto life jackets which use the United Moulders Mk5 Inflators.

The new MK5i Cartridge UMA 5000 will fit UML Mk5 and Pro Sensor inflators. HOWEVER the UMA 5000 has a green end cap and is made specifically for the UML Mk5 Auto device.

If you have a UML Pro Sensor Model recommend that you use the UMA 5001 which has a black end cap.

UML recommend existing MK5 users to upgrade to the Mk5i Cartridge to secure improved performance particularly in heavy seas.

All RTS cartridges are fresh stock. Please feel free to enquire before you buy to check the dates of our products.

Check your life jacket regularly. If the green end cap is missing on your cartridge you need to replace it as the auto firing mechanism may be faulty. You also need to check your cylinder.
