Engineered to address the most demanding sealing challenges in extreme chemical environments, our Viton Chemical-Resistant Gasket stands as a premium fluorocarbon (FKM) solution tailored for industries where material integrity directly impacts operational safety. Designed through advanced polymer compounding, this gasket is specifically formulated to withstand the aggressive attack of industrial chemicals, petroleum-derived fuels, and fluctuating high temperatures—critical for maintaining operational continuity in petrochemical refining, automotive powertrains, and aerospace propulsion systems. Beyond its core resistance properties, it solves the industry pain point of frequent gasket failure in dynamic pressure environments: with superior resistance to concentrated acids (including 98% sulfuric acid), strong alkalis, and chlorinated hydrocarbons, it ensures leak-free performance in refining columns, high-pressure pipelines, and offshore drilling equipment. Its multi-layer reinforced structure—integrating high-strength fabric laminates between FKM layers—enhances durability under cyclic pressure loads, while the low compression set (<15% after 70 hours at 177°C) guarantees long-term sealing integrity even after extended service cycles.
Parameter | Value |
Material | FKM/Viton® fluoroelastomer with fabric reinforcement (glass fiber or aramid) |

Unmatched Chemical Resistance: Undergoes rigorous testing to resist degradation from sulfuric acid, nitric acid, ketones, and aromatic hydrocarbons, meeting the strict standards of API 607 for petrochemical processing safety.
High-Temperature Stability: Retains critical elasticity at 200°C (intermittent use) and maintains sealing force at continuous operating temperatures up to 180°C, ensuring reliability in refining reactors, exhaust manifolds, and high-heat process lines.
Durable Reinforcement: Fabric-laminated layers (glass fiber or aramid) enhance resistance to mechanical stress, extrusion, and tear propagation in high-pressure pipelines, reducing the risk of blowouts during system startups.
Low Gas Permeability: Boasts permeability rates ≤0.1 cc/min for volatile gases like methane and ethylene, making it ideal for storage tank sealing where emissions control is mandatory.
Custom Engineering Support: Available with specialized coatings (PTFE spray or graphite) for enhanced release properties, and offered in full-face, spiral-wound, or ring-type configurations to match specific flange designs.
Petrochemical Industry: Sealing critical components such as valves, pumps, heat exchangers, and distillation columns exposed to crude oil fractions, alkylation solvents, and catalyst solutions.
Automotive & Aerospace: Gaskets for turbochargers, fuel injectors, and hydraulic systems in high-performance engines, where resistance to synthetic oils, coolants, and combustion by-products is essential.
Chemical Processing: Handling aggressive fluids in pharmaceutical reactors, industrial dye synthesis tanks, and waste treatment plants processing halogenated waste streams.
Energy Sector: Offshore platforms, subsea pipelines, and onshore refineries transporting hydrocarbons under high pressure and temperature, including sour gas (H₂S-containing) applications with NORSOK M-710 compliance.
