Flex-Tek Group company

What Flex-Tek Group company does

Flex-Tek is a global engineered components manufacturer operating as a division of FTSE 100-listed Smiths Group plc. The company designs, develops, manufactures, and distributes performance-critical rigid and flexible solutions that heat and move fluids and gases in extreme environments. Its portfolio is organized into three segments: Aerospace (engine and airframe conveyance solutions for jet engine and airframe manufacturers, including precision tube assemblies, manifolds, synchronizing rings, and fabricated ducts), Industrial (flexible hose, rigid tubing, sheet metal HVAC products, bellows, and fluoropolymer products for medical, construction, and industrial markets), and Heat (electric resistance heating elements and thermal systems for compressors, clothes dryers, duct heaters, heat pumps, and HVAC equipment). Flex-Tek serves an enterprise customer base that includes Boeing, Airbus, Pratt & Whitney, GE Aerospace, Whirlpool, Electrolux, Trane, and Carrier.

The company operates through more than 20 wholly-owned subsidiary brands including Kreisler, Lewis & Saunders, Titeflex Aerospace, AmniTec, Gastite, Habia Teknofluor, HCP, Royal Metal Products, Thermaflex, Tutco, and others, each retaining specialized product focus and customer relationships. Manufacturing and production facilities are located across the United States (Cookeville TN, Ohio, Portland OR), Mexico, Canada, the United Kingdom, France, Germany, Sweden, India, and China. Flex-Tek pursues a hardware sales revenue model with quote-based B2B pricing, multi-year OEM contracts, and a direct sales motion for aerospace and appliance OEMs, supplemented by distribution partnerships with Ferguson and Watsco in the US construction market. Standalone revenue is not separately disclosed; Flex-Tek's financials are consolidated within Smiths Group plc.

Flex-Tek has executed a sustained and disciplined bolt-on acquisition strategy to deepen its product portfolio and broaden geographic coverage, particularly in North American HVAC. Notable transactions include Royal Metal Products (2021), Heating & Cooling Products (August 2023, adding patented axial and radial seal duct technology), Modular Metal Fabricators and Wattco (October 2024, up to £110m combined, expanding into medium-temperature immersion and circulation heating), and Duc-Pac Corporation (March 2025, acquired at 7.2x trailing EBITDA, extending metal duct coverage into the north-eastern US). The division is positioned within Smiths Group as a portfolio platform serving aerospace, medical, industrial, construction, and domestic appliance end markets.
