Requires a matching Betts weld collar (e.g., 4055AE aluminum or 4055MS steel) and clamp ring. Not a universal gasket; verify your collar dimensions before ordering. Some listings may appear as '16 ELIP.' but the actual dimensions are 12"x16".

The gasket fits between the weld collar and manhole cover in a clamp-ring style assembly, preventing leaks of petroleum and chemical cargo. It should be replaced when the old gasket becomes cracked, compressed, or leaking.
