How do you size an o-ring?

The best way to size an o-ring is by measuring the CS (cross-section) and ID (inside diameter). For measuring the cross-section, it is best to use a caliper, a.k.a. micrometer. If you don’t have one available, various other sizing tools can be used to get a close estimate.

What is the Best O-Ring Material For the Application?

Nitrile (Buna-N) is a general purpose material suited for petroleum oils, water, and some hydraulic fluids.
Ethylene Propylene Rubber (EPR) operates in a temperature range between -60 degrees Fahrenheit to 250 degrees Fahrenheit.

What are the different sizes of O-rings?

O-rings are available in various sizes, and can be ordered based on required nominal inside diameter (ID), outer diameter (OD), and cross-sectional (CS) diameter. These Buna-nitrile O-rings meet standards defined by Aerospace Standard AS568A, which is the Aerospace Size Standard for O-rings.

What is the as568a standard for O-rings?

These Buna-nitrile O-rings meet standards defined by Aerospace Standard AS568A, which is the Aerospace Size Standard for O-rings. Domestic Shipping: Currently, item can be shipped only within the U.S. and to APO/FPO addresses.

What is a Buna nitrile O-ring made of?

This O-ring is made of black Buna-nitrile, is round in cross-section, has a durometer of 70A, and is designed for use in a wide variety of sealing applications. Buna-nitrile can have high tensile strength, and abrasion, tear, and compression set resistance.

What is the Shore durometer of this Buna O-ring?

This Buna O-ring has a shore durometer of 70A. Shore durometer is the hardness of a material, and its resistance to permanent indentation. A higher durometer value indicates greater resistance to indentation on a scale of 0 to 100, with 100 indicating no indentation.

How do you size an O-ring?

Are O rings standard sizes?

There are two main o-ring sizing types: standard and metric. Standard was developed for use in the United States, while the international community uses metric sizes.

Does O-ring thickness 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 much smaller Should an O-ring be?

To provide an effective seal, the O-ring’s inside diameter (I.D.) must be smaller than the piston groove diameter, so that the O-ring is slightly stretched, fitting snugly in the groove. This stretch should be between 1%-5% with 2% as the ideal in most applications. A stretch greater than 5% is not recommended.

Where can I find my ring size?

Measure your ring size with these steps:

Wrap string or paper around the base of your finger.
Mark the point where the ends meet with a pen.
Measure the string or paper with a ruler (mm).
Pick the closest measurement on the ring size chart to find your ring size.

How do I find my ring size UK?

Find a piece of string or strip of paper no wider than 1.4 cm (1/2 inch). Wrap it around the base of the appropriate finger. Use a pen to mark the point on the string/paper where it overlaps, forming a complete circle. With a ruler, measure the length from the starting end of the string/paper to the pen mark.
