At Industrial Experts, we supply precision-engineered spiral wound gaskets designed for high performance and durability. As a trusted spiral wound gasket manufacturer and supplier, we provide sealing solutions that deliver long-lasting reliability across a wide range of industrial applications.

The spiral wound gasket is a versatile and resilient sealing product, known for its ability to maintain integrity under fluctuating temperatures and pressures. Its design combines a V-shaped metallic winding with a soft filler material, commonly Graphite, PTFE, or other high-temperature alternatives, to create a secure and flexible seal.

The result is a gasket that can recover its shape even after exposure to extreme conditions, making it ideal for demanding environments.

Construction and Design

Each spiral wound gasket is formed by spirally winding a metallic strip together with a filler material. Depending on your application requirements, gaskets can also include inner and outer rings for added strength and stability.

We offer a comprehensive selection of sizes ranging from 15NB to 600NB, compatible with ANSI classes 150, 300, 600, and 900, as well as PN10, PN16, PN25, and PN40 standards.

Types of Spiral Wound Gaskets

Type CG

Metallic winding and soft filler with an outer ring only.
Suitable for flat face and raised face flanges up to Class 2500.
The spiral winding (sealing element) consists of preformed metal and filler material for dependable sealing performance.

Type CGIR

Combines metallic winding and soft filler with both inner and outer rings.
Ideal with both graphite and PTFE Filler applications.
The inner ring protects sealing elements from process media and serves as a compression limiter.
Suitable for both flat face and raised face flanges up to Class 2500.

Type R

Made up of only the metallic winding and filler, without solid inner or outer rings.
Best suited for tongue and groove, male to female, or groove-to-flat face flange connections.
Reinforced inner and outer diameters enhance structural stability.
