OSTW Series connectors are standard size round pin 2 pole TC connectors. They connect or extend TC wire and cable to thermocouple sensors, temperature instrumentation and process controllers.This popular series of TC connector is available in all thermocouple calibration code colors. The contact washer feature allows the installer to use a straight wire strip. This greatly cuts installation/termination time and eliminates the torque that is normally associated with wire that is looped around a termination screw.

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.
