Raw Material

At Hawleys, we supply high-quality gasket material in our jointing range, designed to meet the performance demands of industrial, automotive, steam and process-control environments. Whether you’re replacing existing gaskets, manufacturing new parts or managing maintenance across a plant, our raw materials give you the flexibility to create precise, reliable seals.

Reliable gasket material for industrial sealing and high-temperature performance

Our range includes options suited to heat, pressure, chemical exposure and mechanical stress. From general-purpose gasket sheets to specialised exhaust gasket material, we help engineers, fabricators and maintenance teams build long-lasting seals that support system safety and performance.

Gasket sheets engineered for demanding conditions

We supply gasket sheets and exhaust gasket sheets designed for cutting, stamping or shaping to suit your specific application. With options available across rubber, NBR, PTFE, cork, fibre and metal-reinforced materials, you can create gaskets tailored to engines, pumps, pipelines, pressure systems and more.

Each material is selected for its durability, sealing strength and consistency. Whether you’re managing high temperatures, aggressive chemicals or irregular sealing surfaces, our sheet materials are engineered for dependable results.

FAQs about raw exhaust gasket materials

  • What is gasket material?

    Gasket material is a flexible or semi-rigid substance used to seal the gap between two surfaces. It prevents leaks under compression and is available in rubber, cork, PTFE, graphite, fibre, metal and more — each suited to different temperatures, pressures and chemical conditions.

  • What is gasket material usually made of?

    Common options include rubber, silicone, cork, PTFE, graphite, non-asbestos fibres and metals. Each material is chosen for its resistance to heat, pressure or chemicals depending on the application.

  • What is NBR gasket material?

    NBR (Nitrile Butadiene Rubber) offers resistance to oils and hydrocarbons. It’s widely used in automotive, industrial and aerospace applications where oil resistance and durability are essential.

  • What is the best gasket material?

    It depends on the application. Graphite suits high heat, PTFE handles strong chemicals, silicone works where flexibility is needed and rubber performs well in many general sealing tasks. The environment determines the “best” material.

  • What are the characteristics of paper gasket material?

    Paper gasket material is made from cellulose fibres and synthetic resins. It performs well in low-pressure, low-temperature applications such as small engine components and pump housings.

  • How does exhaust gasket material handle high temperatures?

    Exhaust gaskets use high-temperature metals or composites such as graphite or ceramic. These withstand extreme heat and intense thermal cycling in exhaust manifolds and engine systems.

  • What are the benefits of cork gasket material?

    Cork provides excellent compressibility and flexibility, ideal for uneven surfaces or low-torque applications such as electrical equipment and transformer housings.

  • What are the limits of sheet cork gasket material?

    Sheet cork generally suits moderate pressure environments and temperatures up to around 120°C, depending on the binder composition.

  • How do I choose the right gasket material?

    Consider temperature, pressure, chemical exposure, flange condition and whether the joint will experience movement. Each factor influences material selection and long-term performance.

  • Which gasket materials work best in harsh environments?

    Aramid-reinforced materials with nitrile binders perform well under chemical exposure and high-temperature stress, making them suitable for demanding industrial applications.

  • What role do aramid fibres play in gasket materials?

    Aramid fibres enhance strength, heat resistance and durability. They help gasket materials maintain stability in high-stress environments such as combustion engines and heavy industrial systems.
