thicknesses up to 1/4".
When ordering, specify:
¦Style number

¦Thickness
¦Material (metal or metal and fller)
Plus specify (according to diagram below):
1. Outside diameter
2. Inside diameter
3. Rib width
4. Radius of rib
5. Bolt circle radius
6. Distance from center line of gasket to center line of
ribs
