Marlin Thermocouple Wire manufactures fiberglass thermocouple wire for foundries and aluminum processing plants from our Westlake, OH facility.
Foundries, soak pits, and aluminum processing need abrasion-tough braids and overbraids that survive molten-metal environments—Marlin builds those constructions with Type K/J color coding and optional calibration.
Industry buyers need constructions, documentation, and connectors that match process duty—not generic commodity wire.
We manufacture specialty thermocouple products, run a NIST-traceable lab, and sell to both end users and distributors across the United States.
