BETOOLL HW0130 8pcs Petrol Engine Cylinder Compression Tester Kit Automotive Tool Gauge

Worked great, nice quality

Muy buena calidad

I have given this compression tester 4 stars because it is extremely light duty and when you place the thread adaptor onto the hose and screw it firmly into the spark plug hole upon removal the thread adaptor can remain in the spark plug hole and the hose comes out by it's self. Depending the design of the engine and how difficult it is to get to the thread adapter it can be very difficult to remove. You can tighten the adapter to the hose with a couple of pliers and that problem goes away. The price is very good and the product is with the money. For occasional DIY it is totally sufficient.

Nice for the price

This is a very nice kit.I already have a 14 mm extension tube that runs down that you can put the tester on. I’ve never been comfortable with the testers that you put a rubber hose in with an O-ring because on a rare occasion it’s really hard to get those out and I’m speaking from a spark plug it down inside the head, for example, on a twin motor like it’s a great price. I think you’ll be happy with it.What about the rubber hoses have the solid straight tube and one angular tube that you put the meter directly on and you don’t have to worry about something coming loose. You just have somebody in the car tap the starter a few seconds and then you read the spark plug cylinder kit.

Looks great haven’t used yet but quality for the money is great!

This is a great tool. Works great

I have compression but it’s not very accurate. I checked it against my air compressor and it read 115 psi. The compressor was at 90 psi. The engine I checked had 130 psi new but I got reading from 100 to 160.
