This is our database of CPU block fitting compatibility. For each block we have, we try to fit a pair of each brand, type, and size of fitting. Some cases there just isn’t enough spacing between the ports for anything but small compression fittings (or even any compression fittings at all) and in some cases there are other compatibility issues that would go unnoticed with basic measurements. For this reason, we will not be including measurements of fitting spacing or barb dimensions–it doesn’t tell the whole picture with compatibility.
Want to emphasize that every block and fitting combo, it’s actually tested–we have each block we test and have a pair of each fitting we test. In some cases, we do leak testing or other forms of in-use testing as well.
This database will be updated as we get blocks in to test, so if you keep a close eye on it, it will also indicate what blocks are going to be tested next.
