What Falex does

Falex Corporation, founded in 1927 as Faville-LeValley Corp. in Chicago and headquartered in Sugar Grove, Illinois, is a private US manufacturer of precision tribology and petroleum testing instruments. The company designs and builds hardware for evaluating friction, wear, lubrication, and material properties of fuels, lubricants, and materials, with a portfolio spanning the Falex Four-Ball Tester, Block-on-Ring, Pin & Vee Block, Timken, MCTT, TAA, Ellipsometer 430 ETR, Thermal Oxidation Stability Tester, High Performance Grease Tester, and other specialized instruments. More than 40 of its testers are approved or specified in over 150 ASTM standards globally, and the Ellipsometric Tube Rating (ETR) method is the official referee method for ASTM D1655-14c disputes in aviation turbine fuel deposit analysis.

The company serves four primary verticals: aerospace (fuel/lubricant/material qualification), petroleum and maritime (IMO 2020 and ISO 8217 compliance), manufacturing (wear/material testing), and military/defense (mil-spec testing). It generates revenue through three streams: (1) capital equipment sales of instruments manufactured in the USA, (2) fee-per-use laboratory testing services leveraging over 85 years of testing experience, and (3) hands-on training programs delivered at the Sugar Grove Learning Center. Distribution is primarily direct B2B enterprise sales in North America and through the wholly-owned European subsidiary Falex Tribology NV in Belgium (established 1999) for Europe and the Middle East, supplemented by Compass Instruments as a reseller partner.

Falex operates with 11-50 employees, holds ISO 9001:2015 certification, and is led by President Thomas Peterson (since 2016), CEO of Falex Tribology Dirk Drees (since 2000), Lab Manager Nick Heckenbach (effective February 2026), and Latin America Area Manager Michael Anderson (ASTM Fellow). The company has no disclosed external investors, no parent company, and is privately held with no cap table in the public record.
