What does the -E- mean versus the -SS- description for the PAVE-Mate I connectors?
The -E- in the PAVE-Mate I description refers to the hex area being molded epoxy that includes the o-ring groove, while the threads and jam nut are still metal 300 series stainless steel and the conncetor shells are nickel-plated aluminum. There is no difference in performance between the -SS- or -E- versions, only a slightly higher price for the -SS- VS housing, where available. Slightly more care should be followed per the installation instructions for the -E- versions, so parts are not over tightened, which is unnecessary and could cause damage.
