Type | Description |
|---|---|---|
 |
ring-IE |
Soft gasket protected by a metal jacket named "eyelet". Prevents erosion of the gasket material when turbulent flow is present. Can prevent diffusion of gas through the body of the gasket material. |
 |
Z3 |
Filler material enclosed in a double metal jacket. Open at the outside diameter. |
 |
Z9 |
Filler material is completely enclosed in a double metal jacket that covers both inside and outside diameters. Ideal for applications like boilers, heat exchangers, and similar applications. |
 |
Z13 |
Completely closed, with open gap, oval section. |
 |
GG3 |
Similar to type Z9 but with additional corrugated surfaces. More resilient. Needs less clamping force. Better performance in cycling temperature. |
 |
G1 |
Corrugations provide multi contact with the flange facing. Good in cycling temperature. |
 |
G2 |
Same as type G2 with facing of soft gasket material. Relatively light bolting force is required. Good for flange faces in bad condition. |
 |
G3 |
Ideal for high temperature and big diameters. The fibre cords can be graphited for more sealing. |
