Reviews

Rated 5 out of 5 by Jerry from Thermocouple plugs I would not have bothered to review these, but I have been buying only this brand for years. We like the terminal connection inside, but what I like best is the cord securing segment. It is cut away inside the body so it actually secures the wire when the 2 halves are screwed together. We actually use these for low voltage plugs vs thermocouple connections, using an 18 ga 2 wire sjoow cable. Simple, cheap, rugged.
