Gaskets
Selecting the Right Gasket for the Application
Spiral wound gaskets are high-performance sealing solutions used to provide leak-proof seals in pipelines.
They are produced in different types depending on whether or not they have support rings, and each is designed for different operating conditions.
Choosing the correct gasket is critical for system safety and performance.
Type R (Without Inner and Outer Rings)
This type, consisting only of a sealing element, is used in grooved flange systems.
✔ Simple structure
✔ Suitable for grooved flanges
✔ Basic sealing solution
Type RW (Outer Ring Only)
This is the most commonly used seal type. It ensures correct alignment thanks to the outer centering ring.
✔ Ideal for RF flanges
✔ Easy assembly
✔ Standard industrial use
Type RWI (Inner and Outer Rings)
This type, which has both inner and outer rings, is designed for high-pressure and vacuum applications.
✔ Maximum strength
✔ Extra protection with inner ring
✔ Suitable for critical systems
Type RI (Inner Ring Only)
This type, which has an inner support ring, is used in special channel-type flange systems.
