What Are Novus 45 Gaskets?
Novus 45 Gaskets are made from compressed non-asbestos fibre (CNAF) materials. They are produced using aramid fibres and inorganic fillers bound together with a nitrile rubber (NBR) compound.
This composition provides strong compressibility, excellent sealing, and resilience under moderate-to-high pressure and temperature conditions.
Benefits of Novus 45 Gaskets
1. Safe and Asbestos-Free
Made with aramid fibres and a nitrile binder, Novus 45 gaskets are completely asbestos-free and compliant with modern health and environmental standards.
2. Excellent Sealing Performance
They deliver reliable sealing under pressure and temperature fluctuations, reducing the risk of leakage and downtime in operational systems.
3. High Temperature and Pressure Resistance
Novus 45 handles temperatures up to 400°C and pressures up to approximately 100 bar. This makes it suitable for many steam, oil, and process systems.
4. Versatile Across Industries
The gaskets perform well in a wide range of environments, including petrochemical plants, marine systems, power generation stations, and general engineering.
5. Mechanical Strength and Recovery
These gaskets maintain a tight seal, even under bolt cycling or thermal expansion, thanks to their strong compressibility and good recovery characteristics.
6. Cost-Effective and Durable
Novus 45 provides long service life at a competitive cost. This helps reduce maintenance frequency and inventory complexity.
7. Certified for Industrial Use
Available with BS 7531 Grade Y and WRAS certification, depending on batch and supplier. Suitable for potable water and critical service applications.
8. Easy to Cut and Handle
Supplied in sheet form, Novus 45 is simple to cut on-site or in the workshop. It allows for quick turnaround and easy customisation.
Applications of Novus 45 Gaskets
Novus 45 is a general-purpose sealing material suited to many standard industrial environments. It is widely used where reliability, cost-efficiency, and ease of handling are important.
Suitable Materials for Manufacturing Environments
Gasket material selection in manufacturing depends on fluid type, temperature, pressure, and compliance requirements. While Novus 45 is ideal for general service use, other materials may be necessary for more specialised applications.
1. Novus 45 (CNAF)
Suitable for steam, water, oil, and light chemical service. Common in general manufacturing, maintenance, and utilities.
2. Graphite Gaskets
Recommended for high-temperature or high-pressure applications. Used in heat exchangers, exhaust lines, and chemical plants.
3. PTFE (Teflon) Gaskets
Ideal for aggressive chemical environments or food and pharmaceutical sectors requiring non-contaminating materials.
4. Rubber Gaskets (NBR, EPDM, Neoprene)
Used in lower pressure systems and for HVAC, water treatment, and mechanical service.
5. Metallic and Semi-Metallic Gaskets
Essential for extreme temperatures or pressures. Common in heavy manufacturing, oil and gas, and refinery systems.
Issues Addressed by Novus 45 Gaskets
Novus 45 solves many of the common problems faced by industrial operators and maintenance professionals. However, understanding its limits ensures it is applied correctly.
- Limited Chemical Resistance
Not recommended for aggressive acids, strong alkalis, or corrosive solvents. PTFE or graphite gaskets are preferred for such media. - Temperature Thresholds
While rated up to 400°C, prolonged exposure to high temperatures near this limit can reduce lifespan. In these cases, graphite alternatives may be more suitable. - Pressure Capability
Maximum pressure is approximately 100 bar. For systems requiring higher ratings, metallic or spiral-wound gaskets are advised. - Compression Set Risk
As with all fibre gaskets, creep and relaxation can occur over time, particularly under prolonged stress or heat. Proper torque application and regular inspections reduce this risk.
Not Approved for Direct Food Contact
Although some batches meet WRAS approval for water, Novus 45 is not suitable for direct food processing or pharmaceutical applications.
PTFE-based materials are better suited in these industries.
