The difference between the original o ring cross section and the final o ring cross section once installed is known as the compression squeeze.
O ring cross section tolerance.
Axial dimensions of an o ring shall not exceed a depth of 003 in.
Our tolerances are only meant to serve as a guide.
For recommended o ring c s squeeze values please refer to page 11 12.

O ring tolerances for cross section and inside diameter.
Dimensional tolerances for all metric o rings offered by global o ring and seal are in accordance with iso 3601 1b.
Non continuous flats shall be blended out smoothly.
For non standard o rings however there is no industry standard for this several dimensional specifications have to be taken into consideration.
O ring cross section and o ring groove design data from row inc.
To leaks caused by spiral failure of the o ring.
Standard o rings or iso 3601 are given a concrete set tolerance for both inner diameter id and cross section cs.
In general tighter tolerance components or rigid.
The main advantages of larger cross section o rings include being less prone to compression set less volume swell in liquid based on percentage basis and allows for larger tolerance while maintaining an acceptable compression squeeze and compression ratio over full stack up range.

When the cross sectional diameter is on its lower limit no flat ting is permissible.
You can select your tolerance range in the store.
An o ring is a solid rubber seal shaped like a doughnut or torus.
Until now o ring standards have left a gap between the 1 8 and 3 16 nominal cross sections.
0 08 mm and shall not cause deviation from the nominal section of the o ring in excess of the drawing tolerances i e.
