Where do the “m” and “Y” values come from?
The “m” and “Y” values are empirically derived numbers used by gasket designers that have proven satisfactory under general operating conditions and are a figure of merit relating to the sealing area width and the clamping pressure required for a gasket to seal. The gasket factor “m” is the ratio of contact pressure to contained pressure. The “Y” factor is the minimum gasket seating stress.
