An O-ring must be deformed to function properly. In fact, an O-ring that is not squeezed in its application is the wrong O-ring.
To verify you have chosen the right O-ring for you application, use our NEW O-Ring Gland Calculator.
It is easy to use. Just select the seal and application type, input your bore, piston, and groove diameters, and the O-rings inside diameter (ID) and cross section (C/S). The O-ring calculator will show you the % compression, stretch, squeeze, extrusion gap and minimum groove width (with a 10% swell assumed). The recommended % compression is 10-40% (static), 10-30% (dynamic) and the % stretch is 1-5% (when stretch is required).
The tool also offers the ability to email your results to a colleague and export them to a PDF file all with the click of a button.
We are always glad to hear your opinions, so be sure to fill in the feedback form to let us know how we are doing.
