Spinlock UML Re-Arming Kit - 275N
Best essential maintenance kit for 275N lifejacket owners needing reliable re-arming.
This is the Spinlock UML Re-Arming Kit designed for 275N lifejackets. It conveniently includes a 60g CO2 cylinder and the necessary firing head. This kit is suitable for the Deckvest Pro Sensor 275N and can also be used for other manufacturers' lifejackets that utilize the UML inflator system. Please note that if you are re-arming a Solas 275N Lifejacket, which is a twin-chamber PFD, you will need two of these re-arming kits. It is also compatible with the Pro Sensor 5D 275N Lifejacket manufactured before 2018. Due to the CO2 cylinder contents, this product can only be shipped via ground service and cannot be sent via air freight.

Know before you buy
This kit is designed specifically for lifejackets using the UML inflator system. It is compatible with the Spinlock Deckvest Pro Sensor 275N and Pro Sensor 5D 275N models manufactured before 2018, but it will also work with other brands that utilize the same UML firing mechanism.
Each kit contains one 60g CO2 cylinder and the corresponding firing head required to reset your lifejacket's inflation system.
Yes. Because the Solas 275N is a twin-chamber personal flotation device, you will need to purchase two of these re-arming kits to fully service both chambers.
Re-arming is a straightforward process, but it must be done carefully to ensure the firing head is screwed in correctly and the cylinder is secure. Always refer to your specific lifejacket's manual for step-by-step instructions to ensure the mechanism is armed properly.
Absolutely. CO2 cylinders and firing heads have service lives, and you should inspect your lifejacket regularly. If the cylinder shows signs of corrosion or the firing head indicator is no longer green, you should replace the kit immediately to ensure reliability.
