Direct peers

• Garlock (EnPro Industries): US-headquartered manufacturer of fluid-sealing products (gaskets, packing, sealing devices) for chemical, petrochemical and industrial markets. Direct comparable in industrial gaskets and PTFE sealing with global distribution.
• Teadit Group: Brazil-originated, globally operating manufacturer of industrial gaskets, packing and sealing products with strong presence in process industries. Comparable product breadth and international distribution model.
• Greene Tweed: US-headquartered manufacturer of high-performance seals and custom-engineered components, including PTFE- and fluoropolymer-based materials. Comparable specialty-materials approach in chemically aggressive and high-purity applications.
• James Walker (Coates Group): UK-based manufacturer of industrial sealing products, gaskets and expansion joints serving chemical, oil & gas, power and pharma customers. Comparable in custom-engineered sealing solutions and EN/DIN-qualified materials.
• Klinger: Austrian-headquartered manufacturer of industrial gaskets, sealing products and expansion joints, with comparable size to IDT, similar Mittelstand profile, and a heavily overlapping product portfolio in soft-cut gaskets and PTFE-based sealing. Strongest direct competitor in the DACH market.

Others

• SGL Carbon: German-headquartered manufacturer of specialty graphite and carbon-based sealing materials (e.g., SGL SEALING) for industrial process applications. Adjacent material competitor in high-temperature and chemical-sealing niches.
• Daikin Industries: Japanese fluoropolymer and refrigerant manufacturer whose DAIKIN MG3 MOD-FF/HD material is qualified by IDT as a TFM 1600 alternative. Functions as a key upstream material supplier rather than a direct sealing-product competitor.

Broad incumbents

• Trelleborg Sealing Solutions: Division of Trelleborg AB producing precision seals, gaskets and polymer solutions for industrial and process-industry customers worldwide. Overlapping fluoropolymer and elastomer sealing offering; significantly larger, publicly listed parent.
• Parker Hannifin: Global motion and control technologies giant with an industrial sealing division serving chemical, oil & gas, pharma and hydrogen customers. Overlaps with IDT in sealing and PTFE materials at scale; competes across most verticals IDT serves.
• Freudenberg Sealing Solutions: Global market leader in industrial sealing technology, part of Freudenberg Group, offering gaskets, O-rings and material-substitution R&D across all industries. Overlaps directly with IDT in chemical, pharma and H2 but operates at much greater scale and R&D intensity.
