What KLINGER does

KLINGER is a privately held, family-owned industrial sealing, fluid control, and fluid monitoring group founded in 1886 in Vienna and currently led by the fourth generation of the Klinger-Lohr family through Austrian parent KLINGER Holding GmbH. The group designs, manufactures, and supplies gaskets (metallic, semi-metallic, spiral wound, kammprofile, compressed fibre, PTFE and graphite sheet materials), industrial valves (ball, butterfly, piston, gate, globe, check, plug, diaphragm, safety, bellows seal, control), and liquid level gauges (magnetic, reflex, transparent, bi-colour), alongside compression packings, hydraulic seals, insulation sets, and stud bolts. Core technology centres on proprietary material formulations such as KLINGERSIL, KLINGER Quantum, KLINGER TopChem, and KLINGER Milam (rated to 900°C continuous operation), with differentiated products including EcoSeal (up to 10x tighter than standard spiral wound gaskets), Maxiflex/Maxiprofile gaskets, SENTRY reverse-integrity gaskets, and the Safeguard corrosion-control gasket. Manufacturing capacity includes 60,000 spiral wound gaskets per week at UK sites and 18 global production facilities.

KLINGER's commercial offering has evolved from a pure product catalogue into a 'Total Integrity Solutions' model combining physical products, on-site integrity services (flange management, controlled bolting, bolt torquing/tensioning, on-site machining, leak testing and QA/QC, hot bolting, hydraulic testing), and the IntegrityXpert flange management software platform with subscription licensing. The go-to-market is enterprise field sales targeting major operators in oil & gas, petrochemical, chemical processing, aerospace and defence, pharmaceutical, power generation, marine, mining, and emerging hydrogen/energy-transition verticals, supported by 7 UK service centres, 45 operating companies across 60 countries, and channel partnerships (Zamil in the Middle East, GPEC in South America). Pricing is quote-based with multi-year contracts and no publicly disclosed price list; revenue is generated primarily through one-time product sales supplemented by recurring IntegrityXpert subscriptions and professional services fees. The group employs approximately 2,800 people globally and reports €684M in unconsolidated annual sales, with the UK entity (KLINGER UK Limited, headquartered in Bradford) operating 200+ staff across manufacturing sites in Aberdeen, Grangemouth, Immingham, Runcorn, Southampton, and Middlesbrough.
