摘要

The brake servo has a casing (3) with an aperture, into which a flexible seal fits. A vacuum connector fits into an aperture (10) in the seal. The seal has a recess (7), into which a lug (6) on the connector fits, or vice-versa. This ensures that the connector can only be fitted at a predetermined angle to the seal.
