Graphite gaskets - customised solutions for every application

Graphite is a mineral made of pure carbon: as a result, billi graphite gaskets are characterised by their high temperature resistance. Different items are available depending on the respective area of application: the range includes graphite rings, for example, which are used in chemical plants and nuclear power stations. The billi range also includes flexible graphite tapes: The tapes can be ordered in different dimensions, allowing them to be ideally adapted to the stuffing box. Regardless of your specific product selection, with all billi graphite gaskets you benefit from excellent processing quality and uncomplicated handling.

Graphite sheets - maximum stability

The range in the graphite gasket segment is not limited to rings and tapes, but also includes sheets: The many advantages of billi graphite sheets include low permeability to liquids and gases and high resistance to chemical substances. In addition, the sheets made of natural graphite score points with their enormous stability and high resistance to temperature fluctuations. The graphite sheets can be ordered in different versions to ensure that the perfect product is available for every application: For example, you can choose from models with a smooth steel inlay and impregnation.

Questions & answers about our graphite gaskets

When should I opt for a graphite gasket?

Graphite gaskets are used in many areas of industry and trade. They demonstrate their advantages particularly well in applications where special environmental conditions prevail. They can withstand a wide range of chemical influences and work reliably in a wide temperature range from -200 °C to 550 °C. They also cope well with high pressures of up to 300 bar.


What are the possible applications of graphite gaskets?

Graphite gaskets are suitable for a wide range of applications. Basically, there are three types of gaskets with different focal points:

  • Rings
  • stuffing box packings and
  • flat gaskets.

The ring shape is well suited for spindle sealing in a wide variety of fittings. Stuffing box packings seal moving parts, for example in pumps, steam turbines or fittings. They can also withstand high speeds. Flat gaskets are mainly used for flanges and housings.

Are graphite gaskets resistant to high temperatures and chemicals?

Yes, graphite gaskets are also suitable for use in harsh environmental conditions. Thanks to their carbon base, they can withstand both high temperatures and temperature fluctuations. The application range is -200 °C to 550 °C. The seals are also resistant to most chemicals. They can be used at pH values from 0 to 14.

What chemical properties do graphite gaskets have?

Graphite gaskets can withstand the effects of most chemicals. They are suitable for pH values from 0 to 14 and therefore there are only a few contraindications with chemicals for graphite gaskets. At the same time, they are characterised by low permeability to liquids and gases. This makes the gaskets a universal component with numerous possible applications - from the chemical industry to power plant construction.

How temperature-resistant are graphite gaskets?

Graphite is a form of carbon, an element with a very high temperature resistance. Graphite gaskets can therefore be used in a wide temperature range without any problems. They fulfil their function reliably at low temperatures down to -200 °C and at high temperatures up to 550 °C. In the case of vapours, they can even withstand temperatures of up to 650 °C.


Are graphite gaskets punched or cut?

The manufacturing process for graphite gaskets depends on the quantity produced. Smaller order quantities are generally cut. For larger order quantities, however, punching from the sheet is also possible. As the starting material consists of numerous tiny particles pressed together, it tends to crumble when cut. For this reason, punching generally produces more precisely shaped gaskets.
