How We Do It

Experience, Expertise & Focus

Our success lies in our experience, expertise, and concentration on the aerospace-defense market segment. ICC provides:

  • Best-in-class value-added assembly processes
  • Continued expansion of line card and product offering
  • Deep inventory levels and value-added assembly capacity
  • A focused sales team with deep product and industry knowledge

Value-Added Assembly

Military connector buyers are asked to source many different parts from multiple suppliers. ICC answers that challenge by assembling MIL-SPEC connectors in-house from QPL (Qualified Products List) manufactured components, a process called value-added assembly. In simple terms, that means less overhead for us and a lower cost for you, with one-stop shopping, competitive pricing, and availability for your connector assembly built to exacting specifications. Whether you need the most common military connector configurations or the most obscure, ICC has the components readily available to assemble. ICC builds thousands of military connectors from stock and assembles full MIL-SPEC lines in two days or less*, one of the fastest assembly times in the industry.

*T’DA (Two Day Assembly) not available on all lines
