Use them all time. The earth bars are great. Always compression glands, the cost is negligible & way better job.

use flex glands every time. screwing the gland in breaks the neoprene seal, without you needing to cut it away first. with SWA, you can use banjos on the outside.

The banjo needs to be attached to the gland by a locknut of doing this, trapping it between the gland and the plastic is not good as the plastic will flex with time and cause it to become loose.
