Custom Durable High Temperature Resistant Graphite Gasket¹

Product Description Our flexible graphite rings (also known as graphite packing rings) are high-performance sealing components designed for high temperature and pressure applications. Manufactured from 99% pure expanded graphite, these rings offer exceptional thermal conductivity, chemical resistance, and self-lubricating properties.  Our main objective is to continuously exceed our customer's expectations by providing them with high performance gaskets and sealing products, competitive pricing, on-time delivery and exceptional customer service. Key Features:- High Temperature resistance- Excellent compression resistance - Superior chemical stability (resistant to most acids, alkalis, and organic solvents) - Flexible sealing- Customizable sizes 10 Reasons to Use Flexible GraphiteThanks to its structure, which provides it with the remarkable properties described below, the primary use for flexible graphite is in the sealing sector.Compressibility: Flexible graphite can be compressed to a maximum density limit of 2.25 (ratio between mass & volume). The choice of initial densification is a major factor in the optimization of the final product's characteristics.Resiliency: Flexible graphite has a capacity for resiliency of about 10% in volume, making it possible to maintain seal performance over a broad temperature range.Creep/relaxation: Flexible graphite has a very low creep rate in its service temperature range and holds up to high pressures.Temperature resistance: In a reducing or inert atmosphere, flexible graphite retains its characteristics over a broad range of temperatures, from -196°C to 2500°C (-320.8°F to 4532°F) (sublimation temperature = 3500°C/6332°F). In the presence of oxygen, graphite forms CO or CO2 from 500°C to 550°C (932°F to 1022°F) upwards for high temperature grades. The speed of oxidation depends on the surface in contact with the oxidant object.Aging: Flexible graphite is one of the non-metallic materials that is least affected by aging. This property is not influenced by temperature.Radiation performance: Flexible graphite resists aging from high levels of radiation: no visible effect at 10-22 neutron/cm2 .Chemical inertness: Flexible graphite, which contains no binders, withstands most chemicals, such as mineral acids and solvents.Lubrication: Flexible graphite is self-lubricating and has a low coefficient of friction (less than 0.10 with steel).Processing: Flexible graphite is easy to cut using conventional manufacturing equipment/techniques.Removability: Flexible graphite adheres very little on sealing surfaces.Applications: Chemical Industry: Sealing for chemical equipment, reactors, pipeline connections, etc. Oil and Gas Industry: Sealing for pipelines, valves, pumps, etc.Energy Sector: Sealing for heat exchangers, boilers, etc.Pharmaceutical and Food Processing: Sealing for pharmaceutical production equipment, food processing equipment, etc. Aerospace and Automotive Manufacturing: Sealing for engines, hydraulic systems, etc.Available in standard grades or can be reinforced with metal inserts for enhanced strength.
