High-Performance Compressed Non Asbestos Fibre Gasket Solutions
Welcome to Indgas, a trusted leader in advanced, safe industrial sealing. As industry moves away from hazardous asbestos materials, our compressed non asbestos fibre gaskets set a new standard for flange sealing. These engineered composites blend high-strength fibres such as aramid, glass, or carbon with elastomeric binders like NBR, EPDM, or SBR, to deliver strong mechanical integrity and broad chemical resistance.
Switching from traditional asbestos gaskets to compressed non asbestos fibre materials has improved sealing reliability in demanding services. Our gaskets offer superior torque retention and strong resistance to blow-out, creating durable, leak-free joints under high pressure and wide temperature swings. Indgas supplies CNAF gaskets that prioritise safety, and technical performance.
Engineered For Extremes:
The Science Of CNAF
Compressed non-asbestos fibre gaskets are built for tough conditions. Depending on the fibre and binder combination, they withstand temperatures from ambient levels up to 350°C to 400°C. That capability makes them well suited to high-pressure flange connections that experience severe thermal cycling.
Chemical compatibility is a core strength. Choosing the right elastomer binder matters, nitrile NBR performs well against oils and fuels, while EPDM offers better resistance to steam and weathering. The compressed fibre construction retains excellent sealability, so flange integrity is maintained against blow-outs and fastener relaxation. The result is less frequent maintenance, and reduced operational downtime.
All CNAF materials supplied by Indgas carry the required certifications, confirming asbestos-free composition and compliance with current workplace health and safety standards.
Versatile Compressed Fibre Gasket Sheets & Cut Profiles
Indgas supplies compressed non-asbestos fibre in formats to suit installation and fabrication needs. Premium sheet materials are available in common thicknesses such as 1.5 mm and 3.0 mm, supplied in full sheets for on-site cutting or for custom gasket manufacture.
For precise fitting, we also supply a range of cut gasket profiles ready for installation, including inner bolt circle rings, full-face gaskets, and bespoke shapes machined to exact specifications from your CAD drawings. Material grades include steam-rated CNAF sheets, potable water-safe gaskets, and petrochemical-grade composites, so the right gasket is provided for each service.
Industrial Applications
For CNAF Gaskets
Indgas compressed fibre gasket products meet demanding sealing needs across multiple industries:
- Petrochemical & Refining, secure seals for pipelines, valves, and heat exchangers exposed to aggressive fuels, oils, and hydrocarbons.
- Power Generation & Steam, high-temperature steam lines and boiler flanges benefit from CNAF grades reinforced with aramid or wire mesh for added strength.
- Water & Wastewater Treatment, reliable sealing for potable water systems and wastewater pipelines prevents contamination and leaks.
- General Manufacturing, robust gasketing solutions for compressors, heavy pumps, and industrial machinery requiring dependable flange sealing.
Using compressed fibre gasket materials, Indgas supports critical systems with proven durability and performance.

Technical FAQ
What Is The Maximum Operating Temperature For A Compressed Non-Asbestos Fibre Gasket (CNAF)?
Maximum operating temperature depends on the fibre and binder, but premium CNAF grades typically tolerate temperatures up to 350°C to 400°C.
How Do I Choose Between NBR And EPDM Binders?
NBR is the preferred binder for oil and fuel resistance, making it suitable for petrochemical services. EPDM offers better performance against steam, weathering, and many mild chemicals. Match the binder to the service fluid and operating conditions.
Are CNAF Gaskets Suitable For High-Pressure Steam?
Yes, especially versions reinforced with aramid or wire mesh, which are designed to withstand high-pressure steam applications reliably.
Can I Get A Custom Compressed Fibre Gasket Cut From A CAD Drawing?
Yes, Indgas provides custom gasket cutting services to deliver precise fits for unique flange profiles.
