When sealing reliability matters, gasket selection can make or break your system.
At Fox Global, we specialise in providing industrial-grade flange gaskets tailored to mining, construction, water, oil & gas, and process industries. Whether you need a fibre gasket for potable water, a rubber compound gasket for slurry and dewatering, or a spiral wound gasket for high-pressure pipelines, choosing the correct material and configuration is essential for leak-free performance.
In this article, we break down the differences between:
- ✅ Fibre Flange Gaskets
- ✅ Rubber Compound Flange Gaskets
- ✅ Spiral Wound Flange Gaskets
- 🔄 Full Face vs Ring Type Gaskets
🔩 Gasket Function in Industrial Pipe Systems
Flange gaskets provide a static seal between two flanged pipe ends, ensuring the system holds pressure without leaks—despite vibration, pressure spikes, temperature changes, or chemical exposure.
The wrong gasket can lead to:
- System leaks or blowouts
- Pipe or flange surface damage
- Premature gasket failure
- Safety hazards and compliance issues
🟤 Fibre Flange Gaskets
📌 Description
Made from compressed fibre materials such as non-asbestos, CAF (compressed asbestos fibre) alternatives, cellulose, or graphite-bound aramid fibres.
✅ Advantages
- Excellent chemical resistance to water, steam, oils, and mild acids
- Ideal for potable water, HVAC, and general industrial services
- Cost-effective and readily available
- Suitable for temperatures up to 200–300°C depending on type
❌ Limitations
- Not suitable for extreme pressures or aggressive chemicals
- Can become brittle over time in high-heat applications
🔧 Applications
Water treatment, light-duty steam lines, air systems, general plumbing, and fire protection pipelines.
⚫ Rubber Compound Flange Gaskets
📌 Description
Made from elastomer blends including EPDM, Nitrile (NBR), Neoprene, Natural Rubber, or Viton.
✅ Advantages
- High flexibility, ideal for uneven or pitted flange faces
- Excellent sealing under vibration
- Strong chemical resistance when matched to media
- Suitable for temperatures up to 100–150°C depending on compound
❌ Limitations
- Not ideal for high-pressure or high-temperature steam
- Rubber can degrade when exposed to incompatible chemicals or UV over time
🔧 Applications
Dewatering pipelines, slurry transfer, chemical dosing, irrigation mains, and oil lines.
🌀 Spiral Wound Flange Gaskets
📌 Description
Engineered gaskets combining metallic windings (typically stainless steel) with flexible fillers such as graphite, PTFE, or mica.
✅ Advantages
- Handles extreme pressure and temperature (up to 1000°C and 250+ bar)
- Excellent resilience and recovery under fluctuating loads
- Designed for critical service in oil & gas, power generation, and chemical processing
- Fire-safe and compliant with ASME/API sealing standards
❌ Limitations
- Higher cost and complexity
- Requires precision in installation
- Not suitable for soft plastic or PVC flanges
🔧 Applications
High-pressure steam lines, process gas transfer, chemical plants, refineries, pipelines under thermal cycling.
🧱 Full Face vs Ring Type Flange Gaskets
| Type | Description | Best For | Flange Compatibility |
|---|---|---|---|
| Full Face | Covers the entire flange face with bolt holes | Improved stability, low-pressure systems, large flanges | Table D, E, ANSI, PN, AS2129 |
| Ring Type | Covers only the sealing surface (inner bolt circle) | High-pressure systems, where bolt stress is high | Raised face or flat face flanges |
✅ Full Face Benefits:
- Easier alignment during install
- Extra protection for flange surface
- Often used in water and dewatering pipelines
✅ Ring Type Benefits:
- Less material = lower cost
- Better for metallic flanges in high-pressure sealing
- Less exposure to flange edge erosion
📊 Gasket Selection Lookup Chart:
| Application / Media | Pressure Range | Temperature | Recommended Gasket Type | Gasket Style |
|---|---|---|---|---|
| Potable Water / Air | Low to Medium | Up to 120°C | Fibre or EPDM Rubber | Full Face |
| Slurry / Dewatering | Low to Medium | Up to 100°C | Nitrile or Neoprene Rubber | Full Face |
| Oils / Fuels | Medium | 100–120°C | Nitrile Rubber | Ring or Full Face |
| Aggressive Chemicals | Medium to High | Up to 200°C | Spiral Wound with PTFE Filler | Ring Type |
| High-Pressure Steam / Gas | High (200+ bar) | Up to 1000°C | Spiral Wound with Graphite | Ring Type |
| PVC or FRP Flanges | Low | Up to 80°C | EPDM Rubber (soft face) | Full Face |
