When you need a tough, reliable washer for sealing under pressure and temperature extremes, Novus washers are a proven choice.

At Stephens Gaskets, we’re a leading Novus washers supplier, offering high-performance sealing washers in a range of Novus grades – including the widely used Novus 30 gasket washers.
In this guide, we’ll explore what Novus materials are, how different grades perform, and where Novus washers deliver the greatest value. Whether you need to buy Novus sealing washers for a specific system or want to better understand your material options, this article covers it all.
What Are Novus Washers?
Novus washers are precision-cut sealing components made from Novus sheet material – an engineered fibre-based alternative to asbestos. These novus materials are manufactured by Flexitallic, combining aramid fibres, fillers, and rubber binders to create sheets that offer exceptional resistance to pressure, temperature, and chemical exposure.
Novus washers are commonly used in:
- Pipe flanges
- Steam and hot water systems
- Fuel, gas, and chemical processing lines
- General industrial sealing and insulation
As a certified non-asbestos washers UK manufacturer, Stephens Gaskets machines Novus washers to custom or standard specifications.
Key Benefits of Novus Gasket Materials
1. Non-Asbestos and Safe
Novus materials offer all the sealing strength of legacy asbestos products – without the health risks.
2. High Pressure and Temperature Tolerance
Different Novus grades withstand temperatures up to +400°C and pressures up to 10 MPa, depending on application and grade.
3. Chemical Resistance
Excellent compatibility with steam, oils, fuels, refrigerants, mild acids, and many industrial gases.
4. Dimensional Stability
Novus washers retain their shape under pressure and do not degrade or shrink over time like many lower-grade alternatives.
