which gauge

notsobrite on Sun May 24, 2009 10:13 PM User is offline

Hi. I'm new to this site. I have several kids driving older cars which seem to need ac service every once in a while. All the cars are new enough to have 134A refrigerant. I have a real cheapo single gauge for checking low side. I don't like the fact that I can't monitor psi as i add refrigerant. I have read posts of people critical of cheap gauges. I am thinking about buying a manifold gauge set. As i have looked at them on line a few questions come to mind. i figure i am probably willing to pay 75 to 150 bucks. Maybe a little more. Any input would be appreciated.
1. Preferred brands. Any comments about experience with Imperial, Mastercool, Robinair, whatever??
2. Pros and cons of aluminum vs. brass manifolds
3. Sight glass .....purpose and desirability?
4. I assume with manifold type you can indeed monitor refrigerant as you add it?
5. Why do some sets have 3 and others have more inlets/outlets
6. I'm thinking conventional gauge type would be better for me than lcd digital display type. I figure defective gauges can be replaced. any comment?
Any info or opinions welcome. Initially I would only be adding refrigerant but maybe as i read more and gain experience i might try more.
Thanks for your comments. NOTSOBRITE

Check out Mastercool manifold sets on the sponsors site. I like the second one down myself for the DIY'er. Hope this helps..

You don't need the sightglass

keep things simple, pressures are most important.
