No, the gauges themselves need to have a R134a scale on them.

Be sure to get a set that includes R134a. Yellow Jacket 49983 TITAN 4-Valve Test and Charging Manifold 3-1/8" Gauges (psi, F) for R-22, R-134a, and R-404A

There ya go.............! Compact and subcompact tractors can be mighty handy. My 1996 Kubota L2350DT.....is stilll going strong:

Safe travels my friend. Have a great time. Of course, we'll want to see some pics when you get back. Talk to you soon, Flint.

Good to hear from you, been awhile. Sorry to hear about the radiator. IF your O-Rings are not leaking now.....it might be best to leave them alone (if the LC is not your daily driver). My bypass had never been out.....so didn't want to come out of the Water Outlet easily. Given the limited...

With rear air, you are fine up to about 38 ozs. Let the vent temps tell the story. Each system (because of previous service, wear, dirt, grime, etc) will be a little different.

The good thing about charging the system yourself (vs. taking it someplace) is that you can take the time to 'fine tune' the system. 'Chase' the last 2-3 degrees of vent temps. Adding or subtracting small amounts of refrigerant until you reach the point of diminishing returns. A 'shop' is...

I'm pretty sold on the 49983 set. It is a good quality analog set with all the features you might need. To go 'up' from there, you are talking the newer digital sets that can run well over $1K A good manifold set with good hoses and a 'good' 2 stage vacuum pump is all a person needs to get...

Well....that would explain the low price. They show and mention the manifold set in the ad. So apparently misleading. Sorry for the disappointment.

If it is your plan to service more A/C systems in the future, then invest in a really good manifold set. It will last you a lifetime (replacing only hose seals from time to time). My personal preferece is Yellow Jacket equipment.

I have no problem with 1/4 turn valves. Main advantage is 'quick shut off', but typically that isn't something needed. They would be precise enough if needing to partially open a valve (something that IS frequently needed).

Great question about a very important step. First, (for those who don't already know): The reason we purge the service line is because each time it is connected to a can (or canister) of refrigerant, the hose is open to atmosphere. We don't want any air in the A/C system for a number of...

I'd wager you have some air in the system. If you can find seals for your hose ends, just do that. 27 hg vacuum is probably pretty good (adjusted for altitude, which I don't know? 6,000 ft?). Be sure to let your pump run long enough to boil off any moisture in the system ( a few hours). Also...

Yes Sir, good plan. Be sure your equipment is working properly and of course take your time. A/C work is not something you want to do twice. Let us know how the second attempt goes. I'd like to see (at idle) vent temps around 45°F, improving to about 40 °F vent temps at highway speed. IF...

The pressure reading IS positive pressure. The 'vapor' pressure in the can (depending on ambient temp) is roughly 30-40 psi (for R134a). So when the system has been freshly evacuated, pumped down and still under vacuum, the can pressure is greater and will readily go into the system (on its...
