Just a thought, but are you sure that the actual connectors (blades
and terminals) are made of the same materials as K-type thermocouples?
I ask, because this site doesn't specify which type of thermocouple to
use them with:
http://www.tc.co.uk/thermocouple/the...connectors.htm

It might be worth abrading one or both of the blades with a bit of
sandpaper to see if they're actually just copper.

And if you scroll down, you'll see larger sized connectors for heavier
cable.

Following the k type further

"Manufactured in accordance with standard EN 50212
?High purity thermocouple alloys used for male pin and female socket
constructions
??Bevel tipped pins for easy insertion
Polarised flat pins
Related Connectors"


Some indeed have obviously different colours, but K do look like a
standard nickel plated connector
