Review on Injector Conditioning Injection Coupler Refrigerant Tools & Equipment by Kevin Houston

I purchased this coupler hoping it would be a useful addition to my air conditioning tools. Through trial and error, I found that it is poorly designed and does not securely attach to the injector .It constantly leaks refrigerant and is unreliable. The only positive is that it is relatively inexpensive but the hassle and frustration it causes is not worth the savings..
