MM style molded transition probes feature a thermoset plastic transition and sturdy stainless steel strain relief that protects against sharp bends exiting the transition area.  The thermoset transition provides high dielectric resistance from sheath to ground and has a continuous temperature rating of 900°F (480°C).   

Probes are available in sheath diameters of .125", .188" and .250", single or duplex probes.
