10 best spiral wound gasket
A spiral wound gasket is a specialized type of sealing gasket commonly used in industrial applications, particularly in the fields of hydraulics, pneumatics, and plumbing. These gaskets are designed to provide an effective seal between two mating flanges, pipes, or other components in high-pressure and high-temperature environments. Here's what you need to know about spiral wound gaskets:
Construction: Spiral wound gaskets are constructed by winding a thin metal strip, usually stainless steel, in a V-shaped or W-shaped profile, around a soft filler material, often made of graphite or PTFE (polytetrafluoroethylene). The winding of the metal strip and filler material creates alternating layers, typically several plies of metal and filler.
Sealing Properties: Spiral wound gaskets are known for their excellent sealing properties, especially in applications involving extreme temperatures and pressures. The combination of the metal winding and the compressibility of the filler material allows the gasket to maintain its seal under varying conditions.
High-Pressure Applications: These gaskets are commonly used in hydraulic and pneumatic systems, as well as in plumbing and industrial pipelines where high-pressure fluids or gases need to be contained securely. The design of spiral wound gaskets makes them resilient against the forces generated by pressure.
High-Temperature Applications: Spiral wound gaskets are also suitable for applications where temperature extremes are a concern. The metallic winding provides thermal stability, while the soft filler material helps maintain the seal even when exposed to elevated temperatures.
Chemical Resistance: Depending on the choice of materials for the filler and the metal winding, spiral wound gaskets can offer resistance to a wide range of chemicals and corrosive substances. This makes them versatile for various industrial settings.
Customization: Spiral wound gaskets can be customized to fit specific flange sizes, shapes, and requirements. They are available in various sizes, materials, and configurations to meet the needs of different applications.
Installation: Proper installation is crucial for the effectiveness of spiral wound gaskets. They should be installed between two flanges, with appropriate torque applied to compress the gasket and create a tight seal. Care must be taken to ensure that the gasket is positioned correctly to prevent leaks.
In summary, spiral wound gaskets are essential components in hydraulics, pneumatics, plumbing, and other industrial applications where sealing under high-pressure and high-temperature conditions is required. Their unique design, combining metal winding and soft filler material, makes them reliable and versatile choices for ensuring leak-free connections in various industrial systems.

Sterling Seal
Product description
Spiral Wound Gasket with 304SS Inner Ring, Size 8" pipe, 150# Class Flange, 304SS windings with graphite filler, by Sterling Seal & Supply, Inc. (STCC) API-601 (qty 6 gaskets). Sterling Seal & Supply Style 9000 stainless steel spiral wound gaskets with flexible graphite filler have proven to be reliable in many applications, and allow lower clamping forces than most solid gaskets. The necessity for a gasket to have the ability to recover cannot be over emphasized. The effects of pressure and temperature fluctuations, the temperature differential across the flange face, together with bolt stress relaxation and creep, demand a gasket with adequate flexibility and recovery to maintain a seal even under these varying service conditions. Spiral Wound Gasket is the precision engineered solution to such problems, meeting the most exacting conditions of both temperature and pressure in flanged joints and similar assemblies and against virtually every known corrosive and toxic media. They are used where gaskets with adequate residual stress (stress retention),flexibility and recovery are needed. Spiral wound gaskets are made of a preformed metallic strip and a soft filler material, wound together under pressure, and optionally with an inner and/or outer guide ring. The metal strip holds the filler, resulting in excellent mechanical resistance, resilience and recovery. A v-shaped crown centered in the metal strip acts as a spring, giving gaskets greater resiliency under varying conditions. An optional centering ring accurately locates the gasket on the flange face, provides additional radial strength, and acts as a compression limiter. These gaskets are durable, easy to install and easy to remove. Resiliency and strength make spiral wound gaskets an ideal choice under a variety of conditions and applications. Widely used throughout refineries, chemical processing plants, power generation, pulp and paper, aerospace, and a variety of valve and pump specialty applications.
