Water, steam, oils or gases
For general industrial pipework, start with a fibre-elastomer sheet suited to the fluid and operating conditions.
Start with the fluid and equipment involved, then compare product families by temperature, pressure and the type of sealing required.
A sealing solution is selected according to the fluid, temperature, pressure and whether the application is static or dynamic.
Maximum temperatures and pressures must not be combined automatically. Flange geometry and actual assembly conditions remain decisive.
For general industrial pipework, start with a fibre-elastomer sheet suited to the fluid and operating conditions.
Chemical resistance, compressibility and required compliance guide the choice of PTFE grade.
Distinguish flange sealing from thermal insulation: these functions require different solutions.
For dynamic packing, speed, pressure, temperature and pH must be assessed together.
Send us the fluid, operating conditions, equipment type, dimensions and flange standard. An engineer will review this information before recommending a solution.
The assembly type quickly distinguishes a flange gasket, stuffing-box packing, thermal insulation or a metal sealing solution.
Fibre-elastomer, graphite or PTFE sheets cut to your dimensions.
Engineered packing selected for motion, fluid and operating conditions.
Boards and static packing for heat shields, furnaces, boilers and hot equipment.
Spiral-wound and RTJ gaskets have their own range, with specific flange and standard requirements.
These guidelines help narrow the choice. Exact limits and compatibility are detailed on each product page.
| Family | Starting point | Technical guidance | Available pages |
|---|---|---|---|
| Fibre-elastomer sheets | Industrial pipework and general-purpose flange gaskets | Up to 270 °C and 40 bar depending on grade | |
| Reinforced graphite | Steam and high-temperature static sealing | Maximum 500 °C / 130 bar, not concurrent | |
| PTFE | Chemical, food and pharmaceutical applications | Up to +260 °C and 80 bar depending on grade | |
| High-temperature materials | Insulation and static sealing for hot equipment | Up to 1,000 °C depending on the solution | |
| Pump and valve packing | Dynamic stuffing-box packing | Up to 650 °C / 300 bar depending on grade |
The more precise the operating conditions, the more reliably the material, construction and thickness can be selected.
The fluid, temperature, pressure, equipment type, movement, dimensions and applicable standards must be assessed together. A single maximum value is not enough to validate a gasket.
Reinforced graphite is often considered for steam and high temperatures. PTFE is a common starting point for chemical environments and certain food or pharmaceutical applications.
Spiral-wound and RTJ gaskets are designed for specific flanges, standards and operating conditions. They have a dedicated range so their construction and applications can be compared clearly.
