"I've been using this oil since the early 1970's and have had no problems with my vacuum pump."
"Very good oil, I used it after using the included oil with my vacuum pump and saw an improvement that although small it was an improvement nonetheless."
"Good product and really it's actually much cheaper to buy it in this size than it was to buy single quart because of what they charge for shipping on quarts."
"I use in a freeze dryer which requires top quality."
"It was a perfect product before and it's just as perfect now!"
"I recently had some issues with the dehydrator, and as part of the process I changed the oil, just to ensure that oil was not the problem. The problem is that I used a different oil."
"I run my pump sometimes for 24 + hours for my vacuum stabilization process and it seems to hold up great!"

Best Lab Dosing Pumps
After selecting the desired pH setting from 5.5 to 9.5 pH, the pH controller measures the pH value of the solution and automatically adds pH adjustment (acid or alkaline) to change the liquid’s pH to the selected level.

"Works like a charm."
"Works great and saves me a lot of time and trouble."
"This isn't a 'smart meter' it's just a pH probe and a dosing pump with set variables in the controller. If you treat a gallon, then one pump from this doser and your pH will sky rocket in the set direction."
"You will not regret this purchase."
"Meter will not stay at a consistent or even close ph reading, This causes the dosing pump to give more ph solution then it needs."
"The doser pump seems to be decent, and the sensor is accurate but the actual communication between sensor and doser is terrible, it should only turn on for 5 seconds, turn off, check pH, turn on for another 5, check pH, until it reaches the desired level."

Reviews
Find Best Price at Amazon"This is the correct fitting to connect to the male 1/4" flared fitting on a Yellow Jacket vacuum pump."
"These tanks are the ones that I get from the refrigeration supply house that used in the household/commercial appliance industry."
"Had to do a little AC work and most of the time the adapter to the vacuum pump is gone....so I added one to my tool box and won't have that problem again!"
"I bought this because of the of the reviewer that said he used it as an adapter for the automotive AC hoses to the vacuum pump."
"Bought this to adapt a vacuum pump to my gauge set, but found it is the correct adapter to allow my R12 Can tap to work with my R134 Manifold set!"
"Great to read other buyers otherwise i would never know to get this connector as the pump fitting was for different gauges."
"Decent quality, but wrong threadpitch for my needs."
"Useless adapter, female side has no valve depressor."
