How do you define an O-ring groove?
O-RING GROOVE DESIGN
- Designing the parts of an application where o-rings will be applied is broadly termed “o-ring groove design”.
- An o-ring is contained in a gland and forced to flow into the surface imperfections of the glands and any clearance gaps available to it.
How much should an O-ring stick out?
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.
How do you calculate an O-ring squeeze?
Find your o-ring’s squeeze amount in inches by subtracting the gland depth from cross-sectional diameter with a calculator. For example, if your o-ring’s cross-sectional diameter is 1.25 inches and its gland depth is 1.20 inches, subtract 1.20 from 1.25 to determine that the o-ring is able to squeeze out a total of .
How deep should a groove be for an O-ring?

What are the different types of O-rings?
Due to many applications, there is also a wide variety of O-ring material choices available. Nitrile (Buna), Neoprene, Ethylene Propylene (EPDM Rubber), Silicone, Fluorocarbon (Viton), and PTFE (Teflon) are among the most commonly used compounds for O-rings and seals.
What is cross section of O-ring?
An O-ring, also known as a packing or a toric joint, is a mechanical gasket in the shape of a torus; it is a loop of elastomer with a round cross-section, designed to be seated in a groove and compressed during assembly between two or more parts, creating a seal at the interface.
What does CS mean in O-rings?
cross-sectional diameter
Two dimensions describe the size of an O-ring: its inside diameter (ID) and its cross-sectional diameter (CS).
What size O-ring should I use?
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.
Which is the best O-ring groove design guide?
O-Ring Groove Design Guides. O-ring groove design guides offer default dimensional guidance on the most basic o-ring groove design applications. The best o-rings are useless without the right groove design which becomes increasingly important the more demanding the application environment. Review the general o-ring groove design considerations…
What are global O-ring and seal groove guidelines?
Global O-Ring and Seal has developed o-ring groove design and gland dimension guidelines. These are intended for use in basic design consideration and to understand the core principles involved in o-ring gland/groove design.
What are the dimensions of an O ring?
Based on the cross section (CS) of your O-ring, you will choose the corresponding O-ring groove depth and O-ring groove width dimensions. The O-ring inner diameter (ID) should also stretch approximately 5% over your groove or gland.
