Spiral Wounds 

Spiral Wound Gaskets are manufactured by spirally winding a Vshaped metal strip and a strip of non-asbestos filler material. The metal strip holds the filler, providing the gasket with mechanical resistance and resilience. Spiral wound gaskets can be reinforced by an outer centering ring and/or inner
retaining ring.

Spiral Wound

Gaskets

Spiral Wound Gaskets are manufactured through the spiral winding of a V-shaped metal strip and a strip of non-metallic filler material. The Spiral filler is actually what does the sealing, and the winding contains it from extrusion. This simple design has been modified to 4 common Spiral wound gasket styles.

Spiral Wound Gaskets of all shapes and sizes

1) With an outer metal ring to contain pressure (this is most common due to the fact that sealing internal pressure is most common.

2) Placing a metal ring on the inside dimension for the purpose of preventing the gasket from collapsing into the pipe line in Vacuum applications.

3) Gaskets made with inner and outer rings to contain both Vacuum and internal pressure applications.

4) low pressure applications and minimal vacuum pressure a winding and filler only gasket is sufficient.

Spiral Wound Gaskets Most common applications are in the oil and gas sector. Refineries, and chemical plants have utilized spiral wound gaskets for any application above 150 -300# class especially when temperatures are elevated making cold flow and gasket weep of soft goods more likely. Other Industries using spirals includes: pharmaceutical, shipbuilding, and food processing, power industries and nuclear power stations,

Spiral Wound Brands Include: Lamons USA,, FMI-Spa (Italy), Jeil (South Korea), Leader (USA), Durlon (USA). Regardless of where you are located, we have a factory source near you.

Through our trading partners we also offer Flexitallic, Garlock and other Spiral wound Gasket major brands.

Are there other metal gasket types?

Spiral wound gaskets are a type of mechanical seals used to prevent leaks in flanged joints in pipes, valves, and pressure vessels. They consist of a thin metallic strip and a soft filler material wound together in a spiral fashion, providing a tight seal under pressure.  Spiral wound gaskets have been around for a long time, and are a proven safe technology. However, like any industry there are new products available that can do as good or even better in critical services.  Kamm profile gaskets and RTJ (Ring type joint) gaskets are converting over long-time spiral wound customers.
