OTC 5605 Deluxe Compression Tester Kit for Gasoline Engines with Easy to Read 2-1/2" Dual Scale Gauge, Extra Long Flex Hose, Multiple Adapters, and Storage Case

I'll caveat my review by saying I'm not a professional mechanic. Well, I did have dinner bought for me once after working on a friend's car, so that's sort of like payment. Not sure that qualifies me as a professional mechanic, though. I purchased this kit to work on a friend's car (a different friend, I have at least 4 of them) that had a suspect head gasket issue. I've always wanted a compression tester and this was the perfect reason to buy one. I own other OTC tools and I've been really impressed with them. Along with the other positive reviews here on Amazon, I had no hesitation buying this kit. OTC has another compression tester kit ( OTC 5606 Compression Tester Kit ) that has fewer hoses, but it's only 10 bucks cheaper so I splurged and got this deluxe-o model. The kit contains all sorts of adapters and hoses so I'm guessing it'll work on just about any engine out there. It even comes with a little spare parts baggy that has extra valves and o-rings which I thought was a pretty nice touch. Kit feels solid and well made, and has a nice case to keep all the parts together. The gauge is covered in rubber molding to help protect it from any whacks and bangs during use and is pretty accurate. For what it's worth, I rigged up a contraption to compare the OTC gauge to the gauge on my air tank and they measured the same at 100psi. At least now I know the OTC gauged measures the same as the cheap gauge on my air tank. For me, buying this kit was sort of like a rite of passage. My tool box is full of all types of wrenches, sockets, ratchets, whirly-gig thingamabobs, etc., but this is my first real troubleshooting tool. You know, the type of thing that most people won't have in their garage. I'm feeling a little giddy. Overall, I'm very happy with this purchase and would recommend it to a friend--or in this case on Amazon, I'd recommend it to total strangers.

An excellent tool!!! Quality is superb!!!

This kit has all the adapters I need. The case keeps everything organized and secure. Great product!

Great tool. Easy to use . Good around the shop and at home.

Needed a good compression gauge & found this one. Mechanic I know bought his off the big name tool truck & it's identical to this one, with exception of the gauge face color, & being less than 1/2 of what he paid. Used it about a 1/2 dozen times. Works great, extra rings & valves, & comes in a nice not too big case. Quality control might is why I marked down to 4. When originally received I noticed mine had a gauge with a max reading of 100 psi. Clearly stated on Amazon & other sites was capability to 300psi. I ordered a replacement, sending the original one back, & the replacement came in with the proper gauge. A slight headache but with Amazon Prime policies & super quick shipping I was only set back 1 day. Awesome buy...just check the gauge before you use it :-)

Compression tester

Very nice kit with everything you need…

Been using OTC tools for over 40 years. They are the working man’s tools. Reasonably priced and with quality that is either on par with or above those over priced tool trucks! This tester is just another example of their quality approach for a working man’s tool. Replacement parts are available if you ever need them and product support is excellent! You don’t get that with all the Chinese junk out in the market! Spend a few pennies more and get an accurate, well built tool! This compression tester is accurate, easy to use and came with all the adaptors to do most cars! Even the adapter for the Ford Triton motor! Long hose with quick disconnects made the job a breeze!

Great tool that performs as expected. I purchased this after returning an Orion tester which was no where near accurate. Very happy with the kit overall, it comes with plenty of attachments if required. As others have mentioned the pressure relief button is flimsy but overall the tool is good for the money

A mi papá le gustó mucho

Works great, easy to use, good Quality

We are yet to receive the Input Tax Credit for GST. The supplier has not filed his return. This is completely unacceptable. Can you ensure this close at the earliest. Further the product and supplier both are absolutely pathetic.

Works as it should:-)
