摘要：
A vacuum seal (1) having an O-ring (12) between two mating parts (2) (6). One of the mating parts has a groove (10) configured to receive the O-ring (12). The groove (10) has a modified dovetail shape with at least one side wall (14) having a compound slope formed with a first portion (22) forming an angle of less than 90 degrees with respect to a base wall (18) and a second portion (24) extending substantially perpendicular to the sealing face (4) of the mating part. The cross-sectional area of the groove is less than 95% of the cross sectional area of the O-ring and the width (W) of the groove mouth (20) is at least 94% of the diameter (D) of the O-ring.
