## Questions & Answers

**Q: Can you use it with the new type of gas (1234yf)?**
A: This product can only be used the R134a type gas.

**Q: Will this work on a home ac split unit system? suspect leaking pipes inside brick wall, so i'm avoiding breaking through brick**
A: I was a fridge engineer for forty something year's.......this is a tricky one.....your pipe size will be bigger, and it might well depend on if your leak is on the high side or low side.....have you checked for any signs of oil anywhere? first........tried soap and water on all joints.......is your system on 134 a.....most probably is.....the only real way to have a good chance of finding your leak would be with a electronic leak detector........and finally this gas has rocketed up in price........god knows how many of these you would need.....is there a sight glass? if you can see lots of bubbles your going to need a lot of these.....guess you have nothing to lose and try it first.....but I think your going to have to get someone in with the right equipment .hope this helped

**Q: Could I wait 20mins or so befor a regas at a garage, to give me time to get there if I did it at home.**
A: Depends on how bad your leak is, hope this helps

**Q: hi will this work if the system is empty?**
A: This product needs some Air Con gas in the system for it to work.

### ⭐⭐⭐⭐⭐ Recommended
*by B***Y on 22 August 2025*

It has been very good up to now and no leaks

### ⭐ Nozzle doesn't fit securely
*by J***H on 11 January 2022*

Bought this to seal a small leak on a 2011 vauxhall corsa.I recharged the gas using stp air con recharge...very easy to do.I noticed straight away that the plastic nozzle that goes onto the low pressure port id different from the one that charges the gas. I tried to fit it on but it would not stay in the down position no matter what I done and I lost all my gas due to this. Complete waste of money.
