Questions about this product?

Cover, clamp ring, fastening hardware and gasket included — weld collar sold separately.

The Betts 8008BXB inspection cover assembly closes a matching 20-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.

A removable cover with matched sealing components

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.

Before ordering

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 8008BXB, the 20-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.
