Review on MASTERCOOL 82934 Low Side Manual Coupler by Jack Herrera

I bought this along with a Mastercool 69000/69500 extractor installation (purchase this low side and high side red version 82834-E separately). They are both of good quality and solidly built and I expect them to last a long time with professional use. The blue finish is anodized and scratches easily so I would expect it to wear off fairly quickly if used in a shop. Features a 1/4 MFL (male) connector so make sure this is what your hose requires.
