**Q: It’s now 30/09/2023 what is the expiry/replacement date on these ?**
A: Hi Dave,
Do you mean 30/8? Never mind the expiry date on the UMA5001 cartridges in the Pro Sensor Kit is currently 09/2026.
Best Regards

**Q: Will this fit a fox ks bodyguard 150n life jacket? the original auto firing capsule screwed in underneath the cylinder.**
A: Probably, the typical arrangment is cylinder opposite firing cap so thet the string loaded trigger can fire the pin in the middle assembly into the cylinder to release the gas.
Check the mechanism to find the manufacturer - most often it will be a UML United Moulders – a UK Manufacturer device, others Halkey Roberts – a US Manufacturer.
Hammar – a Swedish Manufacturer check out the RTS site for more details...https://rt-supplies.co.uk/2015/08/07/buying-a-lifejacket-consider-the-inflator/

**Q: We have crewsaver crewfit 150n junior lifejackets.  the original co2 canister is 23g, will the 24g be safe to use or is there risk of over-inflation?**
A: I would ask the folks who know http://crewsaver.com/uk/support/, 5% too much gas may be too much gas.
