Clayborn Lab

What Clayborn Lab does

Clayborn Lab is a privately held US manufacturer founded in 1963 by MIT graduate Vern Clayborn Pfanku that designs and produces precision electrical resistance heat tape and heated tubing products, originally developed for the NASA space program. The core technology uses resistance-based heating elements wrapped in a helix pattern over adhesive-impregnated fiberglass substrate, topped with an aluminum reflector layer that the company states delivers up to 30% better energy efficiency than conventional strip heaters. Additional proprietary features include ML enamel-coated resistance wires and the Tuff Guard outer sheathing introduced in 2013. The product portfolio spans Clayborn Precision Heat Tape, Heated Sample Lines (heated tubing for gas sampling and emission monitoring in diameters from 1/4" to 1 3/4" O.D.), Custom Tape Heaters, and supporting accessories.

The company serves aerospace and defense (NASA, Lockheed Martin, Northrop Grumman, Boeing, ISRO, US Military), automotive and transportation (General Motors, Caterpillar, Ballard Power Systems), environmental and energy (Duke Energy, Anadarko, DCP Midstream), medical and pharmaceutical, industrial manufacturing, and academic research customers globally. Its commercial model is hardware sales through direct engagement with on-staff application engineers, OEM/embedded supply to aerospace primes, and quote-based pricing with 3-business-day lead times for custom heaters and 10-business-day standard lead times for heated sample lines (expedited for a 15% upcharge). Clayborn has been under Horvath family ownership since 1989, transitioned to Justin and Amy Horvath in 2019, and currently operates from Truckee, California with 1-10 employees.
