What Monroe Seals does
OneMonroe, operating also under the names Monroe Engineering and Monroe Seals, is a U.S.-based industrial manufacturer and distributor founded in 1968 and headquartered at 2990 Technology Dr, Rochester Hills, MI. Its core product platform centers on precision rubber sealing components — o-rings, gaskets, seals, extrusions, and custom molded rubber parts — produced using state-of-the-art machinery and a wide library of rubber compounds. Beyond sealing, the company operates an expansive industrial hardware catalog covering roughly 40 product categories including handles, bearings, casters, fasteners, gas springs, hinges, leveling mounts, magnets, military-spec hardware, PCB assemblies, springs, toggle clamps, and wire & cable.
The business model is B2B, sales-led, and quote-based: customers select or specify products through the catalog at catalog.monroeengineering.com, submit RFQs, and are supported by live sales engineers available 24/7. Custom manufacturing is a stated differentiator — if a part is not in the catalog, the company will make, stock, and deliver it to specification. Two sub-brands, OneMonroe Vending (vendor-managed inventory/vending) and OneMonroe Sourcing (procurement services), extend the model into recurring service and broader-spend capture.
The company is privately held with no disclosed external investment, parent, or subsidiary structure; no funding rounds are recorded. Operations are supported by ISO 9001:2015 certification, a published Quality Manual, supplier quality program, and Prop 65 compliance documentation. Distribution is described as domestic across multiple locations, with a tariffs-navigation offering suggesting an active response to trade-policy shifts. Customer concentration, revenue, and headcount are not disclosed in usable form.
