Spiral Wound Gasket | Benefits of its Applications & Choosing Tips

Spiral Wound Gasket

In industrial applications, sealing is an essential requirement to ensure the safe and efficient operation of equipment. The type of gasket used in industrial settings can significantly impact the performance and reliability of the system. One of the most popular types of gaskets used in industrial applications is the spiral wound gasket. These gaskets are versatile and can be used in a wide range of industrial applications. This blog will discuss the benefits of using spiral gaskets in industrial applications.

What is Spiral Wound Gaskets?

Spiral wound gaskets are a type of gasket that is made of a combination of metal and filler material. The gasket consists of a V-shaped metal strip that is wound spirally with a soft filler material, such as graphite or PTFE. The winding of the metal strip creates a series of V-shaped ridges and troughs. The ridges and troughs of the metal strip serve as a sealing surface, while the soft filler material fills in the spaces between the ridges to create a tight seal.

Benefits of Using Spiral Wound Gaskets

High-Temperature Resistance

One of the primary benefits of using these gaskets in industrial applications is their high-temperature resistance. This type of gasket can withstand high temperatures, making them ideal for use in applications that involve high temperatures and high-pressure environments. The metal strip used in spiral gaskets is often made of materials such as stainless steel or Inconel, which can withstand temperatures of up to 2000°F. The soft filler material used in such gaskets, such as graphite, can also withstand high temperatures and prevent leaks.

Excellent Pressure Resistance

These gaskets are designed to withstand high pressure. The V-shaped ridges and troughs of the metal strip create a strong seal that can withstand high pressures. The soft filler material used in the gaskets can also compress and deform to accommodate changes in pressure, ensuring a reliable seal even under fluctuating pressure conditions.

Chemical Resistance

These gaskets can withstand a large variety of substances without deterioration. Metal strips used as gaskets are often constructed of corrosion-resistant metals like stainless steel or Inconel. Spiral gaskets are resistant to a variety of solvents, and the soft filler material used in them, such as PTFE, is chemically inert. As a result, situations where corrosive substances may be present are perfect places to put spiral-wrapped gaskets to use.


These gaskets are versatile and can be used in a wide range of industrial applications. They can be used in applications that involve high temperatures, high pressures, and exposure to corrosive chemicals. Spiral gaskets are commonly used in industries such as oil and gas, chemical processing, power generation, and aerospace.

Easy to Install

Flexitallic spiral wound gaskets are easy to install and require minimal training to install correctly. They can be easily installed by hand, and there is no need for special equipment or tools. The gasket can be easily trimmed to fit the application, making installation quick and easy.

Tips to Choose the Right Spiral Wound Gasket for Your Application

  • Determine the operating conditions, including temperature, pressure, and media.
  • Choose the right gasket material based on the operating conditions, such as graphite, PTFE, or metal.
  • Consider the flange type and size to ensure a proper fit and sealing.
  • Determine the required thickness and number of winding layers for the gasket.
  • Check for any specific requirements or regulations for the application, such as FDA compliance for food applications.
  • Consult with a trusted supplier or manufacturer for expert advice and recommendations.

The Bottom Line

After reading about the benefits of a spiral wound gasket, you may want to order this product. However, choosing the right one is essential for high efficiency. Thus, you should also pay attention to the tips discussed.
