C-4243 is a universal non-asbestos compressed-fibre gasket sheet made from synthetic/aramid fibres bonded with NBR, designed for dependable flange sealing of liquids and gases in non-severe service conditions.
C-4400 is a high-quality compressed fibre gasket material made of aramid fibres and nitrile rubber (NBR). It provides outstanding resistance to oils, water, and steam, making it the ideal choice for general-purpose sealing applications in pipelines, pumps, and valves.
C-4430 is a high-performance compressed fibre gasket sheet reinforced with aramid and glass fibres and bound with NBR rubber. It provides outstanding creep resistance, stress retention, and chemical compatibility, making it ideal for heat exchangers, pipelines, valves, and refinery or chemical process equipment.
C-4500 is a premium-grade gasket sheet designed especially for the chemical and pulp & paper industries. The material combines carbon fibres and special heat-resistant additives with an NBR binder to deliver strong sealability, dimensional stability and resistance to alkaline and steam environments. Use C-4500 where general-purpose non-asbestos sheets are not sufficient and a higher temperature/pressure capability is needed.
C-4509 is a premium high-pressure compressed-fibre gasket material based on carbon fibres and high-temperature additives with an NBR binder and expanded-metal reinforcement — designed for demanding steam, alkaline and high-load applications.
C-8200 is a glass-fiber reinforced gasket sheet with an acid-resistant binder, designed for long-term sealing in aggressive chemical services. Excellent resistance to strong acids/alkalis, low creep and robust mechanical performance — datasheet available on request.
Premium graphite gaskets made from flexible expanded graphite and metal-reinforced constructions (spiral wound, ring-type, and jacketed). Engineered for high temperature, wide chemical compatibility and long-term tightness in industrial process applications. Custom cut and certified options available.
Mica gaskets are flexible high-temperature sealing and insulating components made from natural mica sheets or mica paper assemblies. They provide excellent thermal stability, electrical insulation and low creep for heater elements, lamp fittings, thermal equipment and electrical enclosures. Custom sizes and reinforced versions available.
Quantum is a unique fiber-reinforced gasket sheet manufactured with an HNBR matrix. It combines high temperature capability, broad media resistance (oils, steam, fuels, alcohols, acids) and excellent mechanical performance — available in standard sheet sizes and custom cut gaskets.
Modified PTFE Gasket — SOFT CHEM — multi-directional expanded PTFE sealing sheet engineered for ultra-high chemical resistance, exceptional creep-resistance, and reliable sealing at low bolt loads for industrial, food & pharm, and glass-lined systems.
Top-Chem 2000 is a silicon-carbide filled PTFE sealing sheet engineered for low creep, superior chemical resistance and long-term tightness in demanding flange joints.
Top-Chem 2003 is a PTFE gasket sheet filled with hollow glass-microspheres, engineered for high compressibility and reliable sealing at low surface loads. Excellent chemical resistance for acidic/alkaline services; available in food-grade/FDA conforming variants.
