Why Choose Kaxite Seals for Your Spiral Wound Gasket Needs?
ISO 9001 certified with 25+ years of experience, we offer OEM spiral wound gasket services, express delivery for urgent orders, and competitive factory prices. Every gasket is 100% inspected and comes with material test reports. We support custom sizes, special alloys, and non-standard fillers to meet your exact process conditions.
A spiral wound gasket is formed by winding a pre-formed metal strip (V‑shaped) and a soft filler material around a central mandrel, creating a resilient, semi-metallic seal. This unique construction offers a “spring-like” action that maintains sealing contact under fluctuating bolt loads, thermal cycling, and pressure surges. It conforms to flange surface imperfections, ensuring a tight seal even on worn or damaged flanges. For applications requiring extreme corrosion resistance, we offer special materials spiral wound gaskets using Alloy 20, Monel, Inconel, and Hastelloy.
The choice of metal and filler is critical and depends on service conditions. Kaxite Seals offers a comprehensive portfolio to match your pressure, temperature, and media requirements.
| Component | Available Materials | Key Properties & Typical Applications |
|---|---|---|
| Metal Windings | 304 SS, 316 SS, Alloy 20, Monel, Inconel 600/625, Titanium, Carbon Steel, Hastelloy B/C | Provide strength and spring-back. 316SS is standard for general chemical service; high-nickel alloys resist extreme temperatures and corrosion. Ring joint gaskets are an alternative for certain high-pressure applications. |
| Filler Material | Flexible Graphite, PTFE, Ceramic (Mica), Non-Asbestos (Aramid / Glass) | Primary sealing element. Graphite excels in high temperatures; PTFE for broad chemical compatibility; Mica for oxidising atmospheres. We also supply expanded graphite gaskets for similar services. |
| Centering Ring | Carbon Steel, 304/316 SS, or matching winding metal | Provides radial stability, prevents over-compression, and guides placement. For tongue-and-groove flanges, we recommend inner & outer ring styles for full encapsulation. |
All Kaxite spiral wound gaskets are manufactured to precise dimensions in accordance with major international standards. We stock a wide range of standard sizes for quick dispatch, and custom dimensions are produced with short lead times.
Spring-like action maintains seal despite thermal cycling and pressure fluctuations – perfect for high-cycle applications.
From vacuum to 25,000 psi, and cryogenic to 1000°C (depending on materials). Nuclear-grade options also available.
Metallic structure resists bolt load loss, ensuring long-term sealing integrity – reduces maintenance costs.
Conforms to minor scratches, warpage, and tool marks on flange faces – saves flange resurfacing costs.

Q: When should I choose a spiral wound gasket over a soft cut gasket?
A: Spiral wound gaskets are recommended for medium to high pressure/temperature, critical services, and cyclic conditions. For bulk orders and OEM projects, we offer competitive pricing. Contact our sales team for a custom quote.
Q: How do I select the right metal and filler?
A: Consider the chemical compatibility, temperature, and pressure. Kaxite Seals provides free material selection guidance. You can also view our FAQ page for more details. We supply samples for testing upon request.
Q: Can spiral wound gaskets be reused?
A: No. Reuse is strongly discouraged because the filler embeds and the metal windings deform during initial compression. Always install a new gasket – we offer bulk discounts for large volume purchases.
Q: What is your minimum order quantity (MOQ)?
A: We have no fixed MOQ for standard sizes – we support small trial orders as well as high-volume production. Request a price list for your specific quantity.
Q: What quality controls does Kaxite Seals apply?
A: We use certified raw materials, precision CNC winding, 100% dimensional inspection, and batch crush/recovery testing. Certificates of Conformance and Material Test Reports are provided for full traceability – essential for API and ASME-compliant projects.
Q: How can I get a sample or place an order?
A: Simply fill out our inquiry form or email us directly. We will respond within 4 hours. We support online ordering, proforma invoice, and various payment methods including T/T and L/C.
