Cover, clamp ring, fastening hardware and gasket included — weld collar sold separately.
The Betts 8007BXB inspection cover assembly closes a matching 16-inch clamp-ring manhole while allowing the cover to be removed for tank inspection and access. This configuration combines a zinc-plated steel cover and clamp ring with a black Buna-N gasket.
Choose this assembly when you need the cover-side components rather than a new tank-mounted collar. Confirm the existing Betts model and collar condition before ordering; nominal diameter alone does not establish fit.
| Feature | Benefit |
|---|---|
| Clamp-ring closure | Secures the cover to its matching collar with the gasket between the mating surfaces. |
| Separate weld collar | Lets you retain a serviceable matching collar or select a new collar for the tank material. |

Match the gasket to the tank contents and service temperature. Inspect the collar sealing lip and clamp-ring components, and replace damaged or worn parts with the correct Betts replacements.
| Check | What to confirm |
|---|---|
| Existing assembly | Confirm 8007BXB, the 16-inch size and the matching Betts collar. |
| Collar installation | If installing a new collar, match its material to the tank and fixture it during welding to keep it flat and round. |
| Clamp-ring condition | Do not return a ring with distorted clips, compromised welds or contacting ends to service. |
| Safe assembly | Address residual pressure, tank contents, fall and pinch hazards. Follow current Betts installation and inspection instructions and complete required leakage checks. |
