Gland Size vs Entry Thread



When specifying a gland there are two important factors:-
  • The gland size required to fit the cable you are using
  • The entry thread required to fit the equipment into which you are fitting the gland.

Below is a table showing you the gland sizes and the entry threads available. If what you require is not listed below, a gland size 20s with a 3"NPT entry thread, for example, it still may be possible to achieve your requirements by using an adaptor/reducer.
