Seal & Design

What Seal & Design does

Seal & Design is a family-owned custom sealing product manufacturer and distributor headquartered in Clarence, New York, operating four divisions across the northeastern United States and Canada (Clarence NY, Syracuse NY, Rochester NY, and Toronto ON). The company specializes in custom-fabricated O-rings, gaskets, seals, molded rubber and plastic components, EMI/RFI shielding, thermal interface materials, venting products, and the patented ChamFlex fire-retardant hose assembly line. Core manufacturing capabilities include die cutting, waterjet cutting, kiss cutting, compression/injection/transfer molding, rubber extrusion, PSA lamination, and rapid prototyping using state-of-the-art pneumatic knife and waterjet machines. The company holds ISO 9001:2015 certification across all divisions, IATF 16949:2016 automotive certification (continuously since 2003), and ITAR Registration, qualifying it to serve regulated industries including automotive OEMs and Tier 1 suppliers, defense contractors, mass transit railcar manufacturers, HVAC OEMs, medical device manufacturers, electronics, hydraulics, and emerging EV/energy storage markets.

Seal & Design operates as a Preferred Converter for three major material manufacturers—3M, Rogers Corporation, and Saint-Gobain—giving it distribution rights and technical support for premium product lines including PORON and BISCO foams, VHB tapes, ThermaCool gap fillers, and silicone foam rubbers. The company also distributes SKF SLC seals (30M+ units/year through partner) and Hallite Seals. Revenue is generated primarily through quote-based custom manufacturing orders, with recurring revenue from Vendor Managed Inventory (VMI) and EDI programs that embed Seal & Design into customer supply chains. Value-added services include custom packaging, barcoding, kitting, and assembly. In January 2025, Seal & Design acquired Chamberlin Rubber Company, expanding its mass transit and industrial elastomer product portfolio.
