Engineered Silicone Products

Engineered Silicone Products is a private U.S. medical device company focused on prosthetic suspension products and silicone-based components for the orthotics and prosthetics market. The company develops, manufactures, and distributes prosthetic liners, knee sleeves, socket valves, gel accessories, alignment devices, and suspension systems for prosthetic users and clinicians. ESP positions itself as a family-owned American manufacturer, with products manufactured and assembled in the United States. Its portfolio includes established branded products such as the Lyn Valve, Opti-Seal suspension system, FlexiSleeve, and pre-flexed liners. The business appears to operate as a commercial-stage niche manufacturer rather than a drug-development biotech company.
