UML MK5 Replacement Cartridge and Clip for MK5 Automatic Inflator

Description

The UML MK5 Replacement Cartridge and Clip is an original re-arming kit designed specifically for the UML MK5 Automatic Inflator used in inflatable lifejackets. This kit includes the water-activated cartridge and the retaining clip required to restore the automatic inflation function after deployment or scheduled replacement. It is essential to note that this product does not include the full automatic inflator mechanism, CO₂ cylinder, or complete lifejacket assembly. Designed to meet marine safety standards when used with compatible equipment, the MK5 cartridge activates upon water contact to trigger inflation. Proper installation must follow the manufacturer’s re-arming instructions to ensure correct operation and continued compliance with safety requirements.

How the Indication System Works

The indication on the standard MK5 Automatic inflator allows the user to establish if the system has been fired. The standard MK5 Automatic inflator does not indicate if a pierced CO₂ cylinder is accidentally refitted to the inflator during the servicing procedure. The CO₂ cylinder must be checked each time you don your lifejacket to ensure it is not pierced and it is tightly screwed in by hand. In addition the cartridge must be checked to ensure it has not passed the replace by date, it is also fully screwed on tightly by hand and water is not restricted from entering the system.

There are 2 forms of indication :

1. The Automatic Indicator
2. The Manual Indicator

Both indications must be green, the Automatic Cartridge must be fully fully screwed on hand tight and must be within the printed Replace By Date and a fully screwed in hand tight, full CO₂ Cylinder for correct operation.

The Automatic Indicator is positioned on the base of the Automatic Firing Mechanism.
GREEN indicates OK, and RED indicates STOP/NOT USABLE.

The Manual Indicator is positioned on the side of the firing head.
GREEN indicates OK, and RED indicates STOP/NOT USABLE.

These should checked each time the lifejacket is worn.

If either or both of these indicators are red or missing please refer to the Re-arming Instructions below.
