Fibre Jointing

Fibre Jointing Gaskets

ASG offers a wide range of non-metallic gaskets, thanks to a broad network of suppliers and material manufacturers, some of which are needed for specific applications. One such range of products on offer from our vast catalogue are fibre jointing gaskets, which consists of a varied choice of material types each with its own unique properties to meet particular application demands. The quality of the cut and finish of the gasket is just as important as the material used, therefore we ensure our in-house manufacturing team follow our customer’s drawings or samples to create an exact match – whether it’s a simple square picture frame gasket or a more complex shape with cut-outs – we can offer a solution. From a one-off sample to multi-thousand runs, we have a machine to quickly and accurately produce perfectly formed gaskets in a range of sizes, these include a number of presses and CNC machines.


What is a Fibre Gasket? 

Gaskets are a cut shaped piece of compressible material, sometimes in the form of a pad, washer or strip which is placed between two surfaces to create a seal, provide cushioning or insulation. Most people will instantly choose sponge or rubber when looking for a compressible material for sealing and gasketing applications, however in many cases,  a ‘fibre’ based material could also be an option. Fibre jointing gasket material is made of fibre strands held together with a resin, different fibres can be used to determine the gaskets compressibility, temperature range and strength.


Why use Fibre Jointing Gaskets? 

With a raised awareness of environmental and safety issues, using the right types of gaskets and seals has become crucial for many industries to ensure harmful chemicals and emissions are kept contained. Fibre jointing materials are manufactured in a variety of types, using different fibre and binder compositions in order to meet an array of temperature, compression, insulating and chemical resistance properties. Fibre jointing gaskets generally have excellent resistance to chemicals and oils together with a high-temperature range and tensile strength, making them suitable for many industries.



When choosing Advanced Seals & Gaskets Ltd for your gasket needs, you are sure to be offered a number of material options, thanks to our network of material manufacturers and suppliers.   Each type of fibre jointing gasket has its own range of properties, colours, thicknesses, etc –  our most popular include:

Betaflex is a cellulose-based fibre material, which is made using a nitrile binder giving it excellent tensile strength,  low compressibility, good elastic recovery and erosion resistance. Betaflex gaskets are used widely in the industrial and automotive sectors due to their resistance to oils. petrol, diesel and even antifreeze.

Ceramic Fibre material is constructed using ceramic fibres and an organic binder, designed for extreme temperature applications reaching up to 1250℃. Ceramic fibre gaskets have excellent strength and flexibility, excellent insulating properties and thermal resistance.

Gasket Paper gaskets have a high resistance to petrol, oil and water, therefore often utilised within automotive applications (within fuel/oil pumps and filters). It is not recommended for industrial use due to its lack of resistance to chemicals and heat. 

Graphite foil is available in a number of grades and is an excellent sealing material suitable for high temperature and high-pressure liquid, steam, gas and chemical transfers. Graphite foil gaskets can be used where there is exposure to oil, petrol and gas – even nuclear or power generation applications.

Millboard gaskets are made using a material composed of ceramic fibres, clay, inert fillers and binders. Although these gaskets can not be used with direct flame, they can handle temperatures of up to 1037℃.

Non-asbestos fibre – Non-asbestos fibre has been designed to not only replace the original ‘Asbestos’ material but also to be a more superior product with countless desirable properties as the material is manufactured in various formulations, each giving a combination of properties suited for different applications. Non-asbestos fibre gaskets can be blended with nitrile, thus giving fuel and oil resistance properties, with EPDM to create a potable water safe product or with PTFE for chemical resistance, they can also be supplied with a graphite coating to give steam and non-stick resistance properties.   

Presspahn gaskets are manufactured using a brown coloured material manufactured using kraft wood pulp. Presspahn gaskets have excellent physical and mechanical properties, generally used as electrical insulation.

Vulcanised fibre material is laminated plastic composed of only cellulose, with great mechanical strength and conformability. Vulcanised fibre gaskets can work in temperatures up to 110 ℃ anything more will result in the gasket fibres burning or breaking down.


Benefits of Using Fibre Jointing Gaskets

Advanced Seals & Gaskets Ltd offer fibre jointing gaskets in a range of materials, thicknesses, colours and finishes. Each material will provide insulation within certain applications and suitable for various levels of protection required. Some of the materials listed above are available in variants that can offer additional properties such as flame retardancy and higher chemical or temperature resistance for use in the most extreme environments.
