LASO

What LASO does

LASO (legal entity: Arthur Langenhan GmbH & Co. KG) is a German family-owned precision manufacturer founded in 1965 in Olpe, Sauerland, and now run by third-generation Managing Directors Arno Langenhan and Gisbert Langenhan. The company produces aftermarket replacement engine components — principally oil pumps, coolant/water pumps, belt tensioners, oil coolers, and pressure relief valves — for European commercial vehicles (DAF, Deutz, Iveco, MAN, Mercedes-Benz, Renault, Scania, Volvo), passenger cars (BMW, Mercedes-Benz, Porsche, VW), construction machinery (Volvo CE), ship engines, and industrial motors. Its 1,087+ SKU catalog is built on a single Olpe production site using state-of-the-art CNC machining, milling, and turning, with 100% final inspection and testing of sensitive components on proprietary LASO test stations under a DIN EN ISO 9001:2015 quality management system.

The business is B2B and serves the automotive after-sales market through direct sales to commercial fleet operators and independent repair shops, complemented by a distribution and warehousing network that ships globally. Revenue is generated one-time on each spare-part or repair-kit sale at quote-based pricing with no disclosed price list; the value proposition is "fair cost-performance ratio" combined with German-made quality, broad vehicle coverage (including older model lines), and fast worldwide delivery. The company has no external equity investors, no subsidiaries, no disclosed M&A activity, no funding rounds, and operates as an independent Mittelstand enterprise with 51–100 employees and a multi-language (DE/EN/ES) online presence.
