Marlin Thermocouple Wire manufactures fiberglass thermocouple wire for petrochemical and process plants from our Westlake, OH facility.
Petrochemical and petroleum plants need chemical-resistant Teflon constructions, shielded multipair, and documented extension wire for process units—manufactured and certified from Marlin’s Westlake plant.
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.
