International Metal Hose

What International Metal Hose does

International Metal Hose Company, founded in 1957 in Bellevue, Ohio, manufactures flexible metal conduit, tubing, and hose products for electrical, fluid-handling, electronic, and telecommunications applications. Its core technology centers on forming flexible metallic conduit in trade sizes from 5/16" to 4" (electrical) and 3/16" to 12" (tubing and hose), using coated steels, stainless steel, brass, and bronze. The product portfolio spans a general Flexible Metal Conduit line (aluminum and steel, including UL Recognized appliance-grade flex), the International Sealskin™ line of UL- and CSA-listed liquid-tight flexible metallic and non-metallic conduit (including specialty variants: hi-low temperature, oil resistant, computer blue, plenum-rated, and zero-halogen reduced-smoke), Flexible Tubing & Hose (stainless steel interlock and super-flex squarelock), Fittings & Connectors, and a dedicated export catalog. Certifications on individual SKUs include UL Listings under files such as E34028 and E180076, CSA certifications, NEC Article 300.22(c) and 360 compliance, Federal Specification WW-C-566C compliance, and RoHS/WEEE conformance for ZHALT products.

The company sells standard electrical conduit through manufacturers' sales representatives to wholesale distributors, who serve contractors, manufacturers, and value-added resellers. Unique and value-added products are sold directly to OEMs in wire harness and wire assembly manufacturing, automotive, communication, and aircraft end-markets. A separate direct export channel handles both standard products and items developed specifically for foreign markets. Pricing is quote-based (not publicly disclosed), with just-in-time delivery arrangements and guaranteed pricing offered to key customers. The firm is privately held, financially self-funded, and self-describes as stable and adaptive to new product requirements, operating from a single U.S. factory complemented by field warehouses.

Direct peers

• Atkore (AFC Cable Systems): Atkore owns AFC Cable Systems, a leading manufacturer of flexible metal and armored cable products sold through electrical distribution. Most direct competitor with overlapping UL-listed flexible conduit portfolio across contractor, industrial, and OEM channels.
• Electri-Flex Company: Family-owned flexible electrical conduit manufacturer offering a comparable portfolio of liquid-tight, jacketed, and unjacketed flexible metallic conduit with UL/CSA listings. Closest like-for-like competitor in size, customer base, and product breadth.
• Heyco Products: Manufacturer of wire management, wire protection, and cable-related components including liquid-tight fittings and cord grips. Closely comparable mid-market manufacturer selling into OEM and electrical contractor channels with complementary rather than directly overlapping products.
• Anamet / Anaconda Sealtite: Long-established global manufacturer of flexible metal hose and liquid-tight conduit under the Anaconda brand, with overlapping UL/CSA-certified liquid-tight product lines and similar distributor-led GTM into industrial and HVAC markets.

Broad incumbents

• Southwire Company: Vertically integrated wire, cable, and conduit producer serving electrical contractors and OEMs across North America. Overlaps IMH on flexible conduit plus adjacent cable-management products and competing for shelf space at the same distributors.
• nVent Electric: Global provider of electrical connection and protection solutions including enclosures, cable management, and protective products used in industrial and construction applications. Larger, publicly-listed incumbent competing for the same wire-protection and project specification budgets.
• Dura-Line (Orbia): Manufacturer of conduit, cable ducting, and protective products for telecom and infrastructure with breadth across HDPE and specialty duct systems. Overlaps with IMH's telecommunications equipment and infrastructure customers, especially fiber and conduit runs.
• Legrand (Wiremold / Cablofil): Global electrical and digital infrastructure manufacturer with a wide portfolio including commercial-grade cabling, raceway, and cable management. Competes in the same contractor and commercial-construction specification pipeline, though broader portfolio and primarily commercial focus.
• Eaton (Cooper Industries): Diversified industrial manufacturer with electrical and conduit-related products for construction, industrial, and aerospace customers. Larger scale incumbent with which IMH competes indirectly on industrial wire-protection specifications.

Emerging players

• United Steel Products / Valflex / IEP (distributor peer): Specialist electrical conduit and fittings manufacturers/distributors serving niche construction and OEM applications with comparable UL-listed metallic conduit product lines at smaller scale than Atkore/Southwire.
