Everything You Need to Diagnose and Charge a R134A System

Nice set of gauges for the money! Pretty much everything you need for diagnosing and charging an R134A system including can tap, tank adapter and spare seals. Just add a thermometer Taylor Precision Products Classic Instant Read Pocket Thermometer and a pair of safety glasses Safety Works 817691 Over Economical Safety Glasses, Clear. R134A is available at Walmart or on Amazon's website DuPont 3 Cans R-134a Suva A/C Automotive Refrigerant/Freon R134a (12oz Cans). In his first time working with HVAC, my son was able to top off his Chevrolet's system and enjoy cold air in only about 30 minutes. Gauges seemed accurate with no leaks at hoses or seals. The cost of the gauges and 2 cans of R134A was less than 1/3 the price he was quoted for this service locally. Additionally, he has gained a necessary tool and a new skill. It does help to have someone familiar with automotive HVAC walk you through the first time you use the gauges and remember, safety first! He experienced no problems with the high and low quick connects. A tiny smear of lubricant on the inside of the high and low quick release valves allowed them to release quickly and easily. I would rate these a decent set for the home mechanic. Would purchase again!

Good Valve for the money.

Worked perfect for adding refrigerant to my car. I really liked the fact that the quick release fittings did not immediately open the Shrader Valve when attached. You need to screw the valve handle in before it is opened up. The sight glass is a good indicator of how fast the refrigerant is being added. The only thing I would suggest for improvement is a stub out to connect the fittings to on the valve assembly. That way everything stays completely clean.

Haot Days are Over

The Manifold gauges allowed me to recharge my car new cooling system saving me money by taking the car to the dealer. the Manifold gauge is easy to use and read. Can recommend the product due the ease and quality of the product.

Works

Cheaper than harbor freight and works well. Lines leak if not tightned hard.

Recommended

Very good for the price. There is no need to pay more for manifolds with griffe. Connectors run just fine, absolutely no complains of being stuck.

Worked great for 2014 CLS550

First and foremost I, just like everyone else buying this tool, am a weekend warrior shade tree mechanic. My to go place is the local HF, however they didn't have a manifold gauge in stock neither in Tampa nor in Miami due to hurricane Michael. This particular gauge is exact same model as the cheaper version sold by Orion but comes with a can tap (I already had one so didn't care) and most importantly with couplers that can be shut close. 1/2 ACME adapter might become useful if I need to recharge my home A/C. As opposed to the HF gauge this one is missing a bleed valve for the yellow line which I overcame by unscrewing loose the gauge side of the yellow hose letting the air out. Would be nice of the manufacturer to add one. As far as the dreaded "stuck high pressure coupler" problem. I tend to believe this is simply to not understanding the basic concept of needing to shut the engine off and let some pressure out of the high pressure line hose (red) before attempting to remove the coupler. I did have a problem with the LP coupler which turned out to be a user error. In order to put it on I had to shut the valve close and then it went all the way in no problem. I purchased my CLS in June 2017. Been extremely happy with it, got rid of the airmatic suspension which made me even happier. Then in July 2018 the A/C started blowing hot air on the right. Read multiple forums which lead me to believe the problem lied in the heat core exchange valve (even though in that case the left vents would be blowing hot air). My launch icarscan scanner showed no problems. Before going through the painful heat core valve replacement process I decided to give it a try and add 3 OZ of freon. Which solved the problem immediately. Fast forward three months and the A/C stopped working again. Bought an FJC 4910 A/C UV dye, added it with a 5cc syringe inside the yellow hose, put 5 OZ of R134a with NO stop leak until the low line pressure reached 35psi and the A/C is working again. That's how I did it (I am no mechanic so might be wrong): 1. turn off the engine, close the couplers', HP and LP valves. 2. Connect HP and LP couplers. Should go in very easily. 3. Start the engine, turn on the a/c. 4.open the couplers' valves and the blue (LP) valve. Leave the red one closed. 5.close the can valve so it punctures its seal. open the valve. Let some air out from the yellow hose by loosening it up on the gauge side until you see gas bubbles in the window. 6. when the LP line pressure reaches 25-35psi (might vary a bit) close the couplers then the blue valve and can valve. 7.shut off the engine and remove the couplers. might need to open the red valve to let some pressure out. P.S. I will update the review when the A/C UV dye shows where exactly the freon is leaking. Hopefully, it is just a seal and not the compressor. I have high hopes that the gauge will be able to hold -30psi vacuum. If not then it will be shipped back.

nice guages

Bought these to help recharge my AC after freon leak. Works as expected. I do recommend using Teflon tape to help seal the hoses.

Good gauges at a great price

Read a lot of reviews and purchased this set of gauges. I've used them on 4 different vehicles at this point and they have been perfect. No issues at all. Connection's are great with the couple's, the gauges are ready to read and accurate. Great set.

High side port connector is poor quality. High side connector got stuck on two ...

Update: Excellent customer service. Issue resolved with partial refund, will pick up a replacement high side coupler. Recommend this item as an inexpensive solution. High side port connector is poor quality. High side connector got stuck on two different vehicles. First one took me a good half hour to disconnect, was really starting to panic I couldn't get it off. Second vehicle stuck too but I knew to get out my large pliers and beat the crap out of it to get it off. Low side seemed to work just fine. Manifold is OK fine, not bad for a low cost set. Like the sight glass, that's always a plus. Think If I use the Manifold Set again I'll pick up a different set of connectors first to save me the hassle. Guess I should have went with a high end set but since I rarely need the tool I thought I could get away with a minimal investment.
