DESCRIPTION |
| RW |
 |
This style utilizes a centering ring that accurately locates the gasket on the flange face, provides additional radial strength, and acts as a compression limiter. A general purpose gasket suitable for use with flat face and raised face flanges up to and including Class 2500. An internal ring is recommended for applications above Class 600, due to the high available bolt load. |
| RWI |
 |
Style RWI gasket fitted with an inner ring provides added protection. It also helps prevent over compression of the winding. |
| SW |
 |
Spiral winding only the inner and outer diameters are reinforced with several plies of metal without filler to give greater stability and prevent buckling. Suitable for tongue and groove, male-female, or groove-to-flat face flanges. Also available with inner rings. |
