Yellow Jacket 18975 Charge Tool

Very well made tool. Does exactly what it was designed to do. Little pricey but worth every penny.

works great vacuuming down linesets by taking out all valve cores and valve core depressors gets down to a 1000 micron in minutes slows down getting to 300 but still faster then with out these. I bought two. note; you will not be able to get any readings or subcool after you charge the system with the tool installed you must install valve core remove valve core tool and put the valve core depressors back in refer hoses before installing hoses (or buy a second set) to system. I use fieldpiece 480. didnt want to buy a micron gauge or I could have bypassed the 480 manifold and installed refer hoses staight to the pump.. I use the fieldpiece 480 so I can monitor with my device as Im doing other task..

Speeds up the evacuation process and great quality.

Bought a different brand to save ten dollars and it did not work. Yellow jacket works well and for only ten dollars more just save yourself the headache. (And actual headache from refrigerant fumes)

Very useful tool. I had heard good reviews by people who had successfully used it but I was unsure how well it would work for me. As with most things, you have to undergo a learning curve, although with this tool, it was a short, nearly-flat one. The tool does what it claims and it does it very efficiently. Removing the cores from the access ports does indeed simplify and reduce the evacuation times. Highly recommended.

Does what it supposed tondo

Won’t hold a vacuum or pressure with out fiddling with it. I returned.

I have used other similar core tools that looked the same, but only lasted a year, because the rubber seals inside become deformed, cracked, corroded.The Yellow Jacket version is much tougher, not only in the rubber components but also the metal fittings. The ones I received had the vacuum port on the side, same quality as the rest of the piece, cap and leash are also high quality, plastic.This is one tool I'm glad I spent the extra money instead of getting something that looks as good, this piece is a much higher build quality and has already lasted longer than my other, similar, core tools.
