### ⭐⭐⭐⭐⭐ Worked great for Pioneer Mini-Split

Worked well. I used it to install two Pioneer Mini-Split systems. No problems.

### ⭐⭐⭐⭐⭐ Great adapter, woked perfect to vacuum my Mini Split AC
*by A***G on June 20, 2024*

Fit perfectly onto service port of my DELLA 4 zone 36k BTU mini split condenser. I installed (DIY) 36K BTU mini split for my home, system was precharged, but it required all the linesets to be vacuumed before releasing refrigerant into the lines. I bought for this a small compressor that came with adapter for a service port. The original adapter that came with compressor looked ok, but was very difficults to put on service port, required me to use a grip pliers to make it very tight so it would not bleed air. It was very difficult to get it tide as it was poorly made. After trying several times to not much luck, I looked at revies of these compressors and everyone was complaining about poorly made adapter that does not hold vacuum as it should.. So i just bought this new adapter and it worked like a charm. I screwed it on to the service port EASY with my hands only and it kept vacuum super tide, no leakage at all. After I released the refrigerant into the lineset, the adapter came off so easy, that I lost maybe one second of internal pressure, and AC started to run like a charm! Now the whole home is nicely cooled THANKS to this well made little device!
