## Questions & Answers

**Q: Using the silhouette printed on the side of the gauge to identify smaller o-rings, do I use the outer or inner silhouette?**
A: Nicholas, your o-ring should completely cover the white part of the silhouette. This is a bit tricky to do by eye.
There's more to sizing an o-ring than comparing it to the silhouette.  The Busy Corner o-ring gauge you're referencing is made for US sized o-rings.  There are also metric, Japanese and British sizes. The only way to be sure of an o-ring's size is to measure the ID, OD and cross section with a caliper.
For US o-rings, the numbers printed next to each silhouette on the gauge are called "dash" numbers. O-rings made to AS-568 specifications,  no matter who the manufacturer is, will be the same size. So a -105 (dash 105) o-ring will have an inside diameter of .143, an outside diameter of .349 and a cross-section of .103.  The first digit of a dash number tells you the cross section in decimal inches.  0 is .070, 1 is .103, 2 is .139, 3 is .210 and 4 is .275.  Charts for US, metric, Japanese and British sizes are available on the internet.
I likely gave you more info than you requested, but thought it may be of help to others.

**Q: does it measure in metric?**
A: No,this oring gauge measure in Imperial(Inch) sizes.

## Customer Reviews

### ⭐⭐⭐⭐⭐ O ring gauge
*by J***K on December 29, 2025*

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

### ⭐⭐⭐⭐⭐ Works as intended.
*by J***E on March 3, 2025*

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

### ⭐⭐⭐⭐⭐ Excellent o-ring measuring gauge
*by G***N on November 29, 2020*

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.
