Product details

The Pentair 181011 is the replacement 18 in. band clamp assembly with springs. It is the genuine Pentair part, in metal.

What it does

A band clamp is what holds a split filter tank together. Drawn up around the joint, it presses the two halves onto the tank o-ring and holds them there against everything the pump puts into the vessel. The springs in the assembly keep tension on the band as the tank flexes with pressure and temperature.

When to replace it

Corrosion, a stretched band or broken springs all reduce the clamping force, and the joint starts to seep. Because the clamp has to come off to reach the tank o-ring anyway, most people fit a fresh 18 in. tank o-ring, a separate part, at the same time.

Questions and answers

What people ask about this product, answered by our pool techs.

What size is this clamp?
It is the 18 in. band clamp assembly.
Does it come with the springs?
Yes. The springs are part of the assembly.
Is it metal or plastic?
Metal. Pentair lists the material as metal for this clamp assembly.
Should I replace the tank o-ring at the same time?
It is worth doing. The 18 in. diameter tank o-ring is a separate part, and the clamp has to come off to reach it either way.
