What is the smallest O-ring size?
US seal manufacturer Precision Associates Inc has successfully manufactured what it believes is the world’s smallest O-ring. The moulded O-ring has a cross-section of 0.15 mm (0.006 in) and an inside diameter of 0.2 mm (0.008 in).
Does O-ring size matter?
You may choose O-rings from several standard cross-sectional diameters for your application. For all applications, O-rings with a larger cross- sectional diameter tend to have better resistance to compression set. They also have less volume swell in fluids and are less likely to leak if their surface is scratched.
How do I know what size O-ring to buy?
Measure the length and the Cross section of the ring. Then divide the length by π (3.142), this will give you the circumference. Take the Cross section from this to give you the Inside diameter.
How Do You Measure O-ring thickness?
Using a ruler, measure the distance between the outer edges, which will give you the outside diameter (OD) Using the ruler again, measure the distance across the inside of the ring, which will give you the inside diameter (ID) If you have a Vernier calliper, you can use this to measure the thickness of your o-ring.
What is a flat O-ring called?

What is a #1 O-ring?
O-rings are one of the simplest, yet most engineered, precise, and useful seal designs ever developed. They are available in various metric and inch standard sizes. Faucets usually have one or more o-rings to prevent water from leaking out around the spout. …
How do you match O-rings?
How to Measure O-Rings
- Place the O-ring on a clean, flat, level surface.
- Determine the inside diameter by using a ruler to measure from one inner edge to another.
- Use a ruler to measure the diameter, from one outer corner of the O-ring to the other outer corner.
- Finally, measure the cross-section.

What are the types of O rings?
The common materials used in the production of o-rings seals are silicone, polyurethane, fluorocarbon, nitrile rubber and neoprene. Among these types, one of the most widely used is silicon o-rings for the reasons that it is inexpensive, simple to use, effective and can be applied in a variety of applications.
What is a metric O ring?
Different from a gasket, a metric o ring has thick, round edges and is molded to fit a specific profile. They are commonly used for higher pressure applications than gaskets as well, and are found in places like fuel systems, hydraulic seals, and pipe joints.
