Hi Nick, this has been discussed before...
Start here for a quick read up-

Also do a search on the forum for 'lokring' and you will find some more.

We took the plunge and purchased a Lokring set a while ago - selection of fittings and the tool, plus different size jaws and now have a few joints made on different sites.

So far, so good.

We only tend to use the system when other methods would be time consuming,(PITA) i.e. getting a hot work permit that may take a few hours to organise, dragging brazing kit all the way to the roof, or something similar.
I must say though, that with each joint we make, our confidence in the system grows. So far, no leaks.

thanks for the info think i may get one im fed up waiting around for hwp's

Guys - Lokring has been used by the refrig industry for more than 30 years. You can use it with confidence. the advantages are numerous.
Last year the product was approved by TUV for use with R410a.

thanks for the advice guys just looking around for a good price on a lokring kit

Well, have taken the plunge and bought a Lokring kit. Used it today on a 410a split, pressure testing tomorrow so will see how it goes!

Get hold of Lokring for technical advice but I can tell you they state a failure rate of 2 parts / million if installed correctly with the right bonding liquid. It is a bit more expensive than welding and there is the cure time factor (a negative). Tools are not cheap (another negative).
