Example for detector window: Autocad file

Uses Parker 2-171 O-ring in Viton.
The O-ring specs are 7.987” ID and a width of .103”.
The O-ring gland is .110” wide by .090” deep with a 7.965 ID and 8.185 OD. This gives a “squeeze” of .012 (Parker recommends a wider and shallower gland but we found that it distorts the O-ring too much).
