There are two hoses, each measuring about four feet (48 inches) long and fitted with a 1/4" SAE fitting the working pressure is 500 psi and the burst pressure is 2500 psi

A manifold made out of aluminium with a viewing glass integrated into the body

The manifold gauge gets an additional layer of protection and support from the rubber gauge cover, which includes a hook to hang the gauge.

Questions & Answers

Does this work for Toyota Highlander? Is it metric and SAE?

Your Toyota will be able to use it.

Is there a charge system for my car that I need to finish charging?

These adapters are designed to fit the a/c system of a car

What is the difference between high and low pressure connectors? Can they be plugged in as quick connections only?

Those valves are on mine, but as with any overseas item the specifications can (as they say) change at any time. So yeah, that's what I mean. Caveat emptor! I think they do, but let's be honest.

The F° readings will be shown here?

As far as you can tell, the hi-low pressure will only be displayed in different units (psi, bar, etc.).

The manifold set would have cost me a little less, and I regret not spending more money on it

3/5

As a first-time user, I used this on one vehicle and it worked fine. For the money, it was not bad at all. As a pro and a con, I refer to Among the benefits I'm so sorry! The Shrader valve connectors are nice, aluminum knobs, clearly marked for Open and Close directions (not intuitive to people who don't do this often, because everyone assumes you are closing the Shrader valve, as you are pressing it) - br>- It's nice having the witness window on the middle hose / manifold body! - The data does show negative pressure (except for the very slight negative pressure shown The heavy duty plastic case is a great way to store things I found the service to be functional enough however, it has a few cons I'm sorry - There is a very frustrating issue female hose connectors are 1/4" SAE, which are much less common than standard 1/2" ACME connections. It took me a while to figure this out because I needed a can tap connector (did not order) and my local auto shops, etc. only carry 1/2" ACME connectors. If you are shopping online, you have to be careful to get the smaller 1/4" SAE size. Not I'm so sorry! A DEAL BREAKER FOR ALL PARTIES A strange dye is used on the hoses because color rubs off on your hands even when they are As it were, the powder has rubbed off of the rubber and is now beneath the rubber. I'm so sorry! There is a "negative" pressure on the gauges, but it is so small that one might wonder if there is a vacuum, but at the very least one wonders "how much" Rubber is used on the knobs in the high and low pressure sections. Aluminum would be my first choice, but they might be caused by the fact that the manifold gets cold when R134a is being run I'm so sorry! I think it would be nice to have "Open" and "Close" indicators on High / Low manifold rubber knobs, to make it more intuitive. You won't be stranded if you use this, as it works as advertised. To keep this from happening, you must make sure any attachments you buy are 1/4" SAE, rather than 1/2" ACME, which is more common. If you wear clothes you don't want ink/tint on, you better not wear them since the hoses will show color on your hands and any bare surfaces This set of gauges is sure to be on the budget side of things if this is something you're only going to do once or twice. My personal preference, however, would have been to buy a better set, maybe a $100 or $150 set If you factor in the costs of better components and performance, it would have been a superior set for about $50 more.

You will ruin any device that is set up with a defective case

3/5

Although I didn't even make an attempt to test the actual item, I can tell you that the case is improperly manufactured, and it is thickly coated in blue polymer dye. An Amazon reviewer mentioned a damaged counter top (and that batch is still being delivered), and I can see how that could have happened. The only thing I damaged was a seat cover, but if I hadn't noticed it and set it on something valuable or difficult to replace (such as a piece of furniture or carpet) it would have made this more expensive than any other gauge set available. In some instances, the dye even rubbed off on the gauges themselves (though it would not affect their In order to prevent it from staining anything else before I return it to Amazon, I wiped the outside with a little isopropyl.

Despite its permanent stain, the blue case cannot be removed

3/5

Heavy oxidation had taken place on the blue storage case. Now that it is done with me, I can finally put it away. My white countertop has become permanently stained by this. There is no way to remove it with Bleach. There is no way to remove it with hydrogen peroxide. A refund was issued after I returned it.

well as long as you keep in mind that the measurement is in metric

3/5

Mostly works well, but take note that it reads in metric most of the time. And it doesn't have hose docks, so you have to modify the fittings to accommodate loose hoses, but it does for the most part work well for what it is.

When you pay for something, you get what you pay for

3/5

According to the product, it looks like it was designed to meet Chinese standards and manufactured in China. A blue dye is left on your hands and other surfaces after rubbing the case. I don't think the craftsmanship is impressive and the quality seems doubtful to me. Returning it was the right decision for me. With the extra money I have, I'm going to upgrade to Mastercool or Robinair to get something more predictable. Typically, you get what you pay for in the end, as in most cases.

Due to missing pieces and a long wait for replacements, 2 of the pieces stare at the ground

3/5

At the height of summer they took months to send the pieces because 2 pieces were missing.

This is a good product

5/5

There are four units I have bought from my students and they are all working excellently it has been a very good investment compared with the prices of the rest of the market, and it also comes with an excellent carry-on suitcase.
