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 ### ⭐⭐⭐⭐⭐ Review *by J***K on 29 December 2025* Great gauge for finding o ring size. Fits in a tool box or bag. Easy to use. ### ⭐⭐⭐⭐⭐ Review *by J***E on 3 March 2025* Measures o rings nicely just don't stretch the o ring to far or you will get a misreading. ### ⭐⭐⭐ Review *by F***L on 8 November 2022* 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 ## Frequently Bought Together - O-Ring Gauge Make Work Smart, Telescoping O Ring Sizing Plastic Gauge, Slide Style National Type, for Measuring O Rings Inner Diameter, OD, Thickness Gauge Blue - O Ring Sizer Cone and Seal Puller - Multiuse O Ring Gauge Measures The Inner Diameter and Thickness of Standard Imperial AS568 O Rings, Seal Puller Tool Picks O Rings, Rod Seals, Piston Seals, & More - O-Sizer Tape – Combo --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.ma/products/436393252-o-ring-sizing-gauge-slide-style-national-type-telescoping-o](https://www.desertcart.ma/products/436393252-o-ring-sizing-gauge-slide-style-national-type-telescoping-o) --- *Product available on Desertcart Morocco* *Store origin: MA* *Last updated: 2026-04-28*
