Know before you buy
This kit is specifically designed for lifejackets using the UML MK5i inflator. Check your lifejacket's inflator head for the 'UML MK5i' branding or consult your owner's manual to confirm compatibility before purchasing.
No, it is not universal. This kit is compatible with the Deckvest LITE, LITE+, and older DURO models manufactured before October 2018. It will not work with the ALTO 75N, CENTO Junior, or newer 5D models, which require different re-arming kits.
The kit contains everything you need for a standard service: one 33g CO2 cylinder, the UML MK5i inflator mechanism, and the necessary retaining clip to secure the cylinder.
You should replace the re-arming kit immediately after any inflation event. Additionally, it is best practice to inspect your lifejacket annually and replace the cylinder and inflator if there are signs of corrosion, damage, or if the service indicator has changed color.
While the cylinder itself may still hold pressure, it is highly recommended to replace the entire kit—including the inflator mechanism—according to the manufacturer's service schedule. This ensures the integrity of the firing mechanism and the seal, which are critical for safety.
