Product Description
Product Detail
Corrugated Double Jacketed Gasket – Engineered for Thermal Cycling & Extreme Pressure
Kaxite Sealing is a leading China-based manufacturer and supplier of corrugated double jacketed gaskets – a premium sealing solution built upon the proven strength of double jacketed designs. The corrugated metal jacket significantly enhances resilience and provides superior protection to the soft filler material, making it the ideal choice for applications plagued by thermal cycling, high pressures, and fluctuating bolt loads. Whether used in heat exchangers, gas mains, or boiler systems, these gaskets deliver reliable, leak‑tight performance where standard gaskets fail.
As a trusted factory direct supplier in China, Kaxite offers custom sizes, multiple filler materials (graphite, PTFE, ceramic), and competitive wholesale pricing. Request your price list and free sample →
Corrugated Jacket
Enhanced resilience & filler protection
Thermal Cycling
Solves thermocycling problems effectively
High Pressure
Handles extreme pressures with ease
Extra Bolting
Designed for high bolt loads
High Temperature
Suitable for boiler and furnace applications
Design & Construction
- Metal Jacket: Corrugated stainless steel (SS304, SS316, SS316L, or Inconel®)
- Filler Materials: Flexible graphite, PTFE, ceramic fibre, or mica – selected per application
- Corrugation: Precision‑formed corrugations that add spring‑like resilience and protect the filler from extrusion
- Inner & Outer Rings: Optional centering rings for easy alignment (per ASME B16.20)
- Standards: ASME B16.20, DIN 2694, BS 3381, and custom dimensions
Corrugation Advantages
- ✅ Superior resilience – maintains sealing force under thermal expansion/contraction
- ✅ Filler protection – corrugations reduce filler extrusion risk
- ✅ High bolt load capacity – withstands greater tightening without damaging the gasket
- ✅ Excellent recovery – returns to original shape after pressure cycling
Corrugated vs. Standard Double Jacketed Gasket – What’s Different?
| Feature | Standard Double Jacket | Corrugated Double Jacket |
|---|---|---|
| Jacket Profile | Flat / smooth | Corrugated / wavy |
| Resilience | Moderate | High – excellent for thermal cycling |
| Filler Protection | Limited | Enhanced – corrugations act as barriers |
| Bolt Load Tolerance | Standard | Extra bolting pressure capability |
| Best Application | General services | Heat exchangers, boilers, gas mains with thermocycling |
* Both types are available from Kaxite – choose corrugated for demanding cyclic services.
Typical Applications

- • Ceramic Fibre – up to 1000°C, for extreme heat
- • Mica – up to 800°C, non‑asbestos alternative
- • Custom fillers available on request
* Filler selection depends on media, temperature, and pressure. Contact us for free consultation.
Installation & Thermal Cycling Best Practices
- 🔹 Inspect the gasket – check for any damage to the corrugations or filler before installation.
- 🔹 Use a centering ring – ensures proper alignment in the flange, especially for large diameters.
- 🔹 Apply controlled torque – follow ASME PCC‑1 or flange manufacturer's guidelines; the corrugated design tolerates higher bolt loads.
- 🔹 Torque sequence – use criss‑cross pattern in multiple passes to ensure even compression.
- 🔹 Thermal cycling – the corrugations allow the gasket to "breathe" with the flange; re‑torque after the first thermal cycle for optimal sealing.
- 🔹 Reuse potential – if the corrugations and filler remain intact, the gasket may be reused (check manufacturer's recommendation).
Frequently Asked Questions – Corrugated Double Jacketed Gasket
What makes a corrugated double jacketed gasket better for thermal cycling?
The corrugated metal jacket acts like a spring, absorbing thermal expansion and contraction without losing sealing force. This maintains a tight seal through repeated heating and cooling cycles, unlike standard flat jackets which may lose compression over time.
What filler materials are available for corrugated double jacketed gaskets?
We offer flexible graphite, PTFE, ceramic fibre, and mica. Each provides distinct temperature and chemical resistance profiles. Our team can help you select the optimal filler for your specific media and service conditions.
Can this gasket handle high bolting pressure?
Yes. The corrugated design allows extra bolting pressure without damaging the filler or jacket. This makes it suitable for applications requiring very high gasket stress to achieve a reliable seal.
What standards do you manufacture to?
We produce to ASME B16.20, DIN 2694, and BS 3381. Custom dimensions and designs are also available to meet your specific flange requirements.
Are these gaskets reusable?
If the corrugations and filler are undamaged after removal, the gasket can be reused. However, we recommend inspection by a qualified engineer, especially for critical services.
What is the typical lead time for custom‑sized corrugated gaskets?
15–25 days for bulk orders, with express options available. Sample orders can be delivered in 5–7 days.
