What are Liquid Tight Threaded Plugs?

Liquid Tight Threaded Plugs are hexagonally headed plugs made from robust, non-conductive Nylon 6/6.

These plugs are available in Metric, PG, and NPT thread sizes, suitable for sealing unused threaded entries or preventing ingress in machinery and control panels.
