What Trygonal does

Trygonal was a Germany-based manufacturer of high-performance sealing solutions built around elastomers, thermoplastics, and rubber-metal compounds, with documented expertise in polyurethane molded and foamed parts, precision O-rings, and custom-engineered sealing systems. The core product portfolio spans piston seals, rod seals, wipers, guide rings, backup rings, rotary seals, O-rings and O-ring alternatives, gaskets, large-diameter seals, miniature seals, and special profiles, supported by a materials range covering polyurethanes (HPU, XHPU), elastomers (NBR, HNBR, EPDM, MVQ, FPM, Aflas, AEM), and thermoplastics (POM, PA6G, PTFE). The technology lineage traces to the development of the Simmerring approximately 100 years ago, which anchors the company's proprietary compound and process expertise. Operating subsidiaries were maintained in Germany, Austria (three locations), Switzerland, and Spain.

The business model is B2B direct sales with engineering consultation and quote-based pricing, complemented by self-service digital tools (O-ring database, semi-finished products shop, media resistance guide, load calculator for rubber-metal buffers) for standard product procurement. Customers span eleven documented verticals including hydraulics/pneumatics (primary), chemical/pharmaceutical, automotive, medical technology, aerospace, food & beverage, rail, thermal technology, water treatment, mechanical engineering, and valve/fitting technology. On November 1, 2024, Trygonal Group GmbH was merged into Freudenberg FST GmbH as part of the ongoing integration of Trygonal into Freudenberg Sealing Technologies; the merged entity operates as part of the Freudenberg Group, a diversified German conglomerate generating approximately €12 billion in 2024 sales with around 52,000 employees globally. Pre-merger innovation activity included co-development partnerships with DITF Denkendorf (ElastoTex, SensGrip) and participation in the EU Horizon 2020-funded i-TRIBOMAT consortium.
