This item is also available to order individually here.

CURRENT STOCK: REPLACE BY DATE May 2030 or later.

The Mk5i cartridge has been available in two models.

UMA 5000 with Green end cap. This is for the UML Mk5 model of inflator.

UML 5001 with Black End Cap. This is for the UML Pro Sensor Auto inflator which was phased out in 2017.

Because the number of Pro Sensor Auto inflators left in circulation  is falling, it is now difficult to buy and maintain good replace by dates on the UMA 5001 so from Summer of 2025 RT Supplies Ltd will offer only the UMA 5000 with Green End Cap for both inflators ensuring that users get good replace by dates.

Think of the “i” in Mk5i as improved. It has been slightly remodelled from the old version so that the bottom around the cap is smoother. The new Mk5i Cartridge contains a new paper element resistant to the negative effects of high humidity. Nitrile sealing gives added security against accidental water ingress.

Although the replace by date may be in excess of 3 years from the date of first use it is important to be mindful of the guidance given by United Moulders with regards to replacing the Mk5i Cartridge.

Recreational Use: Replace every two years or by the REPLACE BY date whichever is sooner. It is recommended your lifejacket is inspected annually. Refer to your lifejacket manual and keep to service intervals.

Commercial/Professional Use: Replace annually. Do not exceed the REPLACE BY date in any 1-year period. SOLAS approved life jackets are required to be serviced by an authorised service station annually.

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.
