Hello Tony Here [ oldmanfrigy ]

I have used Hychill Hydrocarbon in split systems and car A/Cs and was a trainer assessor for OZ-Chill. My gas is in a 9KG bottle has a normal male tap like the 134a Bottle not like the LPG bottle for my BQ. My gas came from Sprint Auto Parts.

Below is an email address from another OZ-Chill trainer and he may be able to help you.

I would love to know how you get on.
