Why CNAF Gaskets Are Now the Industry Standard

South Eastern Gaskets explains why CNAF gaskets are the industry standard for safe, reliable and versatile non-metallic sealing across Australian industries.

In industrial operations, reliable sealing is essential for maintaining system integrity, preventing leakage, and ensuring workplace safety. The effectiveness of a sealing solution depends heavily on selecting the correct gasket material for the application. Among today’s non-metallic options, CNAF gaskets have become widely recognised for their safety, durability, and versatility, making them the preferred choice across a range of Australian industries.

What are CNAF Gaskets?

CNAF stands for Compressed Non-Asbestos Fibre, a material developed to replace traditional asbestos-based gaskets. These gaskets are manufactured from a blend of synthetic and inorganic fibres bound together with elastomers such as nitrile rubber. The result is a sheet material that offers excellent structural integrity and sealing performance without the health hazards associated with asbestos.

CNAF materials provide stable sealing across varied operating conditions, including moderate temperatures and pressures. Their customisable sheet form makes them adaptable to standard and non-standard flange dimensions, supporting their reputation as a reliable and cost-effective non-metallic sealing solution.

Why CNAF Gaskets Are Widely Preferred

CNAF continues to set the benchmark for general industrial sealing. Its performance attributes make it suitable for many modern engineering requirements, particularly where safety and compatibility are essential.

• Asbestos-Free Safety and Compliance – Removing asbestos from sealing materials has greatly improved workplace safety. CNAF products meet strict Australian standards, providing a safe, asbestos-free option without sacrificing performance—ideal for organisations focused on compliance and worker protection.

• Versatility — Chemical, Thermal, and Pressure Resistance – CNAF materials offer strong resistance to water, oils, fuels, mild chemicals, and steam. With grades suited to various temperatures and pressures, they provide versatile sealing for pipelines, valves, pumps, and general plant equipment.

• Cost-Effectiveness and Practicality for Industry Use – CNAF gaskets are made from versatile sheet materials, allowing custom sizing and reducing the need for large inventories. Their reasonable cost offers strong value for organisations wanting reliable sealing without the expense of specialised metallic or composite options.

• Stability and Future Value – CNAF materials offer long-term stability and durability, helping reduce maintenance needs and downtime. As industries prioritise safer, sustainable options, CNAF remains a reliable and valued choice for non-metallic sealing.

Common Applications Where CNAF Gaskets Excel

CNAF materials suit a broad range of industrial settings, particularly where moderate temperature and pressure performance is required. Their adaptability, chemical compatibility, and ease of fabrication make them suitable across numerous equipment types and operational environments, including:

• Water treatment and utilities (water, steam, mild chemicals) — thanks to chemical resistance and flexibility.
• Petroleum, oil, and gas (low-to-medium pressure) piping, valves, and flanges.
• General industrial and manufacturing — pumps, general piping systems, and equipment requiring regular maintenance or replacement.
• Steam or thermal systems (depending on CNAF grade) — where non-metallic yet heat-resistant sealing is needed.
