Can you use it with the new type of gas (1234yf)?

This product can only be used the R134a type gas.

Will this work on a home ac split unit system? suspect leaking pipes inside brick wall, so i'm avoiding breaking through brick

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

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.

Depends on how bad your leak is, hope this helps

hi will this work if the system is empty?

This product needs some Air Con gas in the system for it to work.

Nozzle doesn't fit securely

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.

Best product I have bought in years

I bought this back in April and to be honest didn’t have much hope it would work.My Mazda had been back and forwards to the Mazda main dealer and to a local air con firm and was a few hundred pounds lighter with no results. The main dealer finally said it was the evaporator under the dash and would cost north of £1200, I was not prepared to spend that sort of money on the car so I went through a winter not bothering with air con. The warmer days came and I missed the air con. So I tried this stuff.The compressor was not working as there was no refrigerant in the system, so I got the AC refrigerant to top up the system first, then the compressor kicked in. I then used this stuff and used as per instructions, then top up with more AC refrigerant. Then crossed everything, it works a treat, if fact better than it ever has at a fraction of the cost. So was it a faulty evaporator or just a leak they couldn’t see we will never know, running now for over two months and still good.Just an update it’s now May 25 and still the air conditioning is working.
