Questions about this product?

Weld collar only β€” manhole cover, gasket, clamp ring and fastening hardware are separate components.

The Betts 3176SL manway weld collar is a 20-inch round, 304 stainless steel collar for a matching Betts clamp-ring-style manhole. It provides the tank-mounted collar beneath the cover; a separately selected gasket seals the joint while the clamp ring holds the cover and collar together.

Select this component when your tank build or repair calls for the exact collar rather than a complete manhole assembly. Match the collar material to the tank shell and confirm the existing manhole configuration before ordering; nominal diameter alone is not a fitment check.

A separate collar for the tank connection

Feature Benefit
Weld-on installation Provides the tank attachment for the matching clamp-ring manhole.
Separate collar Allows collar selection independently of the cover and sealing components.

Before ordering

Fixture the collar during welding so it remains flat and round. Before assembly, inspect the sealing lip and mating parts for damage, corrosion or distortion. Follow current Betts installation and clamp-ring inspection instructions; do not reuse a damaged ring or one with compromised clip welds.

Check What to confirm
Existing assembly Confirm part 3176SL, the 20-inch size and clamp-ring configuration.
Tank material Match collar material and welding requirements to the tank shell.
Mating components Select the correct cover, gasket, clamp ring and hardware separately.
Safe installation Address residual pressure, tank contents, fall and pinch hazards before work; complete required assembly leak checks.
