Spiral Wound Gasket

A Spiral Wound Gasket (SWG) is a type of gasket made from alternating layers of metal strips and non-metallic filler materials, wound in a spiral formation. This construction creates a flexible, yet durable, sealing element that can accommodate a wide range of temperature and pressure conditions.

The metal winding imparts strength and resilience, while the filler material—often made of graphite, PTFE, or other sealing materials—enhances the gasket’s ability to seal effectively, even in harsh, chemically aggressive environments.

Spiral Wound Gaskets are widely used in industries where tight seals are required to maintain system integrity, prevent leakage, and ensure operational safety. They are well-suited for high-pressure, high-temperature applications and environments prone to vibration and thermal expansion.

Best Suited For: High-pressure and high-temperature environments, particularly with raised face flanges where maximum sealing integrity and robust flange protection are essential. Ideal for critical applications in the oil & gas, chemical processing, and power generation industries.

Key Advantages:

• Features a solid metallic outer centering ring for precise alignment during installation and effective compression control, preventing gasket failure due to over-tightening.
• Includes a solid metallic inner ring that provides exceptional radial strength, safeguards the sealing element against fluid turbulence and flange erosion, and minimizes wear and tear on the inner windings, ensuring long-term reliability.
• Available with a diverse range of high-quality filler materials (including graphite and PTFE for superior chemical resistance) and durable metal strip materials (such as stainless steel and carbon steel to withstand extreme conditions).
• Delivers a versatile and exceptionally robust sealing solution for both standard and highly critical industrial operations where zero leakage is paramount, contributing to enhanced safety and operational efficiency.

Best Suited For: Medium pressure and temperature applications on both raised face and flat face flanges, commonly used in automotive, HVAC (heating, ventilation, and air conditioning), and plumbing systems.

Key Advantages:

• Incorporates a solid metallic outer ring that acts as a precise centering mechanism, ensuring accurate and hassle-free gasket placement and preventing misalignment during installation. This outer ring also functions as a compression stop.
• Provides a cost-effective yet highly reliable sealing solution for a broad spectrum of general industrial applications where ease of installation and consistent performance are key.
• Offered with a wide array of filler and metal strip materials to accommodate various media and temperature ranges encountered in typical industrial settings.

Best Suited For: High-pressure and high-temperature applications involving male to female flanges found in vessels, valves, and pumps, particularly in demanding industrial environments dealing with aggressive chemicals and solvents.

Key Advantages:

• Features a solid metallic inner ring that provides vital support and reinforcement to the sealing element, especially crucial in high-pressure and corrosive applications, extending the gasket’s service life.
