What are non-asbestos gaskets

Non-asbestos gaskets are industrial sealing components manufactured from fibre-based materials that do not contain asbestos. They are designed as a safe and compliant alternative to traditional asbestos gaskets while providing reliable sealing performance under pressure and temperature.

These gaskets are typically produced from compressed fibre materials using synthetic fibres and elastomer binders, making non-asbestos gaskets suitable for a wide range of industrial sealing applications.

When do you need non-asbestos gaskets

Non-asbestos gaskets are used when health, safety and environmental regulations prohibit the use of asbestos-containing materials. They are commonly selected for sealing applications involving pressure, heat or chemically active media.

Non-asbestos gaskets are often applied in maintenance and replacement scenarios where older asbestos gaskets need to be removed and replaced with compliant sealing solutions.

Applications of non-asbestos gaskets

Non-asbestos gaskets are applied in flange connections for pumps, valves, heat exchangers and piping systems across industries such as chemical processing, power generation, water treatment and general manufacturing.

They are used in both utility and process systems where reliable sealing performance and compliance with modern safety standards are required.

Non-asbestos gaskets specifications

Type: Non-asbestos compressed fibre gasket sheet (Doniflex-A)
Composition: Aramid/cellulose fibres with elastomer binder (typically NBR) and mineral fillers
Temperature Range: approx. −40 °C to +250 °C (short peaks higher, depending on application)
Pressure Range: medium to high (depends on flange design, bolt load and medium)
Resistance: water, steam, oils, fuels, mild chemicals

Doniflex-A is a general-purpose, non-asbestos fibre gasket material for industrial flange sealing. It offers good mechanical strength and reliable sealing performance in common utilities and process applications. Suitable for cutting flange gaskets, rings and custom shapes from sheet material.

Custom production

In addition to standard Non-asbestos gaskets, we can CNC cut custom shapes and dimensions to your drawing. Suitable for prototypes, small series and repeat production.
