I'm looking at this one 46101 set to replace my two Robinair R12 and 134 manifolds. Any opinions?

really nice gauge set, i like the dedicated vacuum and tank lines less chance of introducing air into the system

I searching for a new manifold, why not seek a unit that uses the liquid filled gauges. We are discovering that some of the newer design compressors, scrolls and rotary vanes are creating some pressure readings that may lead to an improper diagnosis. this is due to the discharge pressure fluxuations. The liquid filled gauges over come these issues.
Worked with a tech some time ago, and he used a set of YJ's....worked well....it is felt that more attention should be paid to the type of sealing that the company utilize for the control valves. Some of these units are quite 'cheap' and this often results in seepage after a period of time.
Check site sponsor for this set.
86972 - Mastercool Professional (4-Way Gauge Set) Comes with liquid filled gauges....134a manual type connectors....have used this set for a long time.....it's a good set. A bit over kill for a DIY'er but stil a great set of gauges.
