 | 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. |
