ORING CORD FOR 21" TNK

The O-Ring Cord for Pentair 21 Inch Filter Tank (24850-0008) is a replacement cord ring (rope gasket / tank o-ring) for sealing the 21-inch diameter Pentair filter tank lid to the tank body. Cord rings are large-diameter, rope-style o-rings that compress between the tank top and body flange to create a watertight seal when the tank clamp is tightened. A deteriorated cord ring is the most common cause of leaks at the filter tank joint. Replace whenever the filter tank is opened for servicing. Verify your tank diameter before ordering.
