Pentair 192320 O-Ring - #2-146, Bulkhead

What This Part Is Used For
The Pentair 192320 O-Ring is used on bulkhead fittings to create a watertight seal between tank walls and plumbing connections. It prevents leaks at filter or equipment penetrations.

Why This Part Matters
Bulkhead seals are exposed to constant pressure and chemical contact. When they fail, leaks can appear at the base of the tank or plumbing connection. Replacing the O-ring restores a secure seal and protects surrounding equipment.
