Fast Fix Thermocouple Connectors

Fast Fix Thermocouple Connectors

(5)
Fast Fix thermocouple connectors provide a rapid, consistent and inexpensive way to create quality hot junctions for base metal thermocouples and insulated thermocouple wire. Applied with a Crimp Tool, Fast Fix makes uniform junctions that do not require the time, experience and welding equipment necessary for welded thermocouple hot junctions. Fast Fix connectors are usable with E, J, K, N, and T calibrations; and can be used with wire sizes from 8 to 30 gauge. Crimp Tools are available for use with Fast Fix connectors, allowing for a precision pressure fit, creating a consistent hot thermocouple junction.
