ABSTRACT:
In a potted-type seal for sealing an opening in a relatively rigid housing stress-relief means is provided to prevent excessive shrinkage-induced stress between the compound and the housing. The stress relief means includes a relatively flexible peripheral lip portion as part of the housing or, preferably, as part of the potting compound, which lip portion flexes when the potting compound shrinks to reduce stress between the compound and the housing.
