This rearming kit will fit all 150N automatic jackets that use the hammar M1A1 (hydrostatic) automatic inflator. (Sometimes mis-spelt as Hammer or Hamar .)

The kit includes a replacement Hammar hydrostatic head, 33g CO2 cylinder fitted to new backing plate, fitting instructions and a fitting key.

*Note we are the only UK supplier who supplies the co2 cylinder fitted to a new backing plate, do not accept a kit without this part!

Our lifejacket cylinders are the very best available, they are zinc coated to reduce rust.

"The Hammer M1A1 rearming kit was very easy to replace especially after watching the video on the Marine Warehouse site. I feel it is a good idea to have an automatic lifejacket and is worth paying the extra. Very good service with delivery by 1st Class Post."
