Longacre 52-52002 Liquid Filled 2-1/2 Tire Gauge, 0-60 psi

This is a very well made and accurate air gauge! One thing's for sure, I'll never use a pencil type air gauge again! I really, really like this air gauge from Longacre. Not just because it incorporates the oil filled buffer, for longer life, and longer sustained accuracy. But what I really like is the larger gauge, it's simply easier to read and hold. The 17" air hose is a great length, and really flexible. Everything about the build and make of this air gauge is high quality. I have one of there more basic models, that isn't oil filled, but I wanted a higher end model, so I can always cross check my readings. Just in case I may drop one or the other, thats enough to make me wonder, Did I just mess up it's calibrated readings. So now with both on hand, I can always double check my tire pressure, and be positive about it. This is a really well made air gauge, with a really nice protective gauge cover, nice and thick to absorb most jarring shocks. This gauge also has a very nice feature, that my less expensive model doesn't have, it's that this model "Holds" the pressure reading after you release, or pull off the air chuck from the tire valve. So one quick push down of the air chuck to get a pressure reading, and then release it, and the gauge is still holding the pressure reading. So now, if you need to take a closer look, you can with this model, and then once your satisfied, you just reset the gauge, all you need to do is to push the release valve, which is the small silver button located on the black metal housing that connects the air hose to the air gauge. This button is also called the bleeder valve. It can also be used to deflate the tire, if you've overfilled your tire by a pound or two, and have your reading, by pushing the bleeder valve, while the gauges air chuck is still depressed on your tire valve, you just push this button, to release air from your tire, then release the button when it reaches the desired pressure reading. Another really desirable feature is this air gauge is Dead On Accurate. I've used it to check my other Longacre air gauge, which is also dead on accurate as this one is, but I took this one up to my cousins auto shop where he has calibrated air gauges, and this 52002 air gauge matched every pressure. I tested it at 20Lbs., 45Lbs., and 55Lbs. Each reading was right on. This air gauge is very easy to hold, very easy to read, and very easy to use. Plus the gauge itself is bigger than Longacre's other less expensive models, which is a big plus for me. This is my second Longacre air gauge, and I really love the both of them, but prefer to use this one. One thing to note about this particular model, is that you need to "Equalize" the pressure in the gauge itself, before your use it. By that I mean each time you pull it out to use, not each individual tire, but if you've had it sitting for a while (unused), and you go to check your tire pressures, the first thing you need to do is hold the gauge upright, and loosen (turn the top screw cap counter clockwise, a quarter turn), and then re-tighten the cap screw (by hand only), so that it's tight. Then use the air gauge as normal. I'd highly recommend this air gauge to anyone considering it! I'm really happy with it!

This is a pleasure to use. Good tires are your best insurance so why not have a good instrument to measure them. I am doing a lot of off roading where I need to air down my tires to 15 psi off road and air them back up before going onto pavement (ARB CKMP12). It takes a little longer to air down than I thought it would but that also helps a hive a precise PSI. I need to know where my tires are at so I don't go below 15 psi and roll a tire off my wheel. When you square up the nozzle it registers and holds the pressure after you remove the nozzle. The equalization valve is easy to use and a great feature. Just be careful to release the nozzle when it's upright or oil will leak out. It also glows in the dark which is good as I will be airing down before sunrise. Over all this is an awesome tool.

I recently have been searching for the tire pressure gauge. Did some research and came across this little gem. Wow! I love it. It has everything you need. I was considering a 4" dial but now, having this in the hand, that seems like it would be way too big for general use. This gauge is extremely well made. Dial is easy to read and the relief valve at the top is very clever. Some key points: Very easy to read Rotates at the chuck (NOT the gauge like others) which is where it needs to be Holds the pressure until you release the button valve. Not sure why you wouldnt want this feature. Liquid filled WITH a relief valve AND a wonderful protective case that is very comfortable to hold. One thing I read in my research that stuck with me is this: A gauge being accurate is good but one that is consistent is far better. Sure, all cars have recommended pressures, but I'm sure there is more then a few of you that bought this as a track-side companion. Those factory numbers go out the window when it comes to "tuning" your tire pressure. I have every bit of confidence that this gauge will provide very accurate readings time and time again.

very high quality gauge. my new standard for gauges. I own half a dozen gauges similar that are not liquid filled that cost half the price of this one. this one is definitely worth the extra money if you like quality and accuracy. Update: Great while it lasted. Unfortunately the needle has now fallen off. its useless now. Of course its past the one year warranty period. never dropped. only used by me. I expected a gauge at this price to last a long time. I'm back to using my old gauges that I've had for 20 years.

This is a well-constructed item that does what it's supposed to. It's more expensive than most, but worth it in my opinion. I like the knob that equalizes the internal and external pressures before you use it. My only negative is that the photo shows that it has a bright white dial, but the actual product has a darker background, which reduces contrast. Also, if the in-between numbers (25, 35, 45, etc) had been omitted from the dial, it would likely improved its readability even more. Finally, the advantages of it being "liquid-filled" were not explained anywhere in the sparse printed material, so I'm not sure that there are any. However, I invite other reviewers to comment on this practice, if they'd like.

I purchased this to replace a broken longacre pressure gauge of the exact same type.1of 2 that I have had for over 6yrs. Used primarily for Motorsport use so accuracy is important. Both of the old gauges have been perfect and accurate and I have been very happy with them. Received the new one and tested over a couple of days to ensure correct readings and yes I released the pressure on the top screw. The new gauge as per the pictures was down 1.5 -2 psi on each test, also for some reason the oil level in the gauge was a lot lower. Don’t know if that makes any difference? I am returning it for a refund and will purchase locally to avoid all this inconvenience.
