For a 6 mm rubber grommet, identify the referenced dimension on the drawing. The mounting hole, internal passage and outside diameter are different features.
Many molded panel grommets use a groove and flanges for retention. Do not assume all parts are held solely by expansion or can be installed from one side. Follow the selected profile's instructions.
Check panel thickness, cable clearance and compound suitability. Rubber can age or crack under unsuitable conditions. Environmental or comparative price claims need supporting information; choose the part using its documented dimensions and performance rather than general claims of superiority.
