No instructions as to what the remedy is.** A: Hi, Regarding the high and low pressure quick connector, it needs to be screwed up to the top during installation, and when it is working, it needs to be screwed down so that the internal needle presses the valve body of the car compressor interface to achieve the connection. **Q: warranty? I purchased this kit last year and just got it out just to find out the r134 cuppers leak and the vacuum hose ends don't fit.** A: Good luck with warranty. Yeah, it's junk. **Q: Does this connect to 1/2" acme tank adapters?** A: Package include 1pc tank adapter, 1/4 inch male to 1/2 inch female, hose fitting 1/4 inch, can tap fitting 1/4 inch, thanks for your question. **Q: How to download the instructions that they say is on the product page?** A: I never downloaded the Manual for this set, I googled a you tube video on how to use the set. ## Customer Reviews ### ⭐⭐⭐⭐⭐ Full air con kit R1234yf. *by on Reviewed in the United Kingdom 22 October 2022* Just the job for sorting your air conditioning out on your vehicle love the fact it is very tidily packed in a case so you can use it anywhere and everything you need to do the job is in the case. ### ⭐⭐⭐⭐⭐ Air con equipment *by on Reviewed in the United Kingdom 22 September 2026* Very easy to operate and read the gauges. ### ⭐⭐⭐⭐⭐ Very reliable gauge set! *by on Reviewed in the United States 15 July 2026* Great purchase seriously.
