This tool is great!
This tool is awesome. I never leave reviews but this little gadget is impressive and accurate. I have a hydraulic repair shop and decided to overhaul my oring storage system. I have thousands of o-rings and this tool was invaluable during this process. There is a bit of a learning curve with the amount of tension you put on the oring when reading the size . This handy little tool can read any oring on the dash system from -001- 475. Overall, if you deal with o-rings in any capacity buy it!

Easy to use, accurated to verify an unknown o-ring size.
This gage is like gages I've used at work to identify mystery o-rings. I needed it for some projects and it worked great. Much easier than trying to measure a flimsy o-ring with calipers. I did verify my first couple of tries with calipers and it was right on the money.

O ring gauge
Great gauge for finding o ring size. Fits in a tool box or bag. Easy to use.

Excellent o-ring measuring gauge
This o-ring gauge is made of heavy plastic, slides freely, marks for o-ring size are printed in white against blue and therefore easy to read. Smaller o-rings can be sized against accurate printed silhouettes on each side of the gauge. All sizes are shown in common "-dash" numbers for easy reference at the local bearing or tubing store. There are slots at the top of the gauge to "size" the o-ring's cross section. Instructions for use are clearing printed on one side so they're never lost and are easy to understand. Overall gauge length is 13.5 inches by 1.25 inches square. As with any extendable gauge, the tension you apply is key to accurate measuring. If this is to be kept loose in a tool box, I'd recommend you retain its cardboard box or have a friend sew a sleeve. This will protect the printing from becoming scratched or grease from making the markings unreadable.

Inaccurate
The gauge read two sizes smaller. The size for a 025 o' ring is shown on the chart as ID 29.87 mm . The vernier caliper measured ID as 33 mm which is for a 027 o' ring. O well, I guess I will have to estimate it up or I might consider returning the tool

Handy tool
Easy to sue, seems pretty accurate as long as you get a feel for how much tension to use. Identifies tons of different o ring sizes. Quality is fine for what it is, easy to read and should hold up well.

Works as intended.
Measures o rings nicely just don't stretch the o ring to far or you will get a misreading.
