Quick overview
- 18 in. band clamp Sized as an 18 in. band clamp assembly.
- Springs included Supplied as the clamp assembly with its springs, not as a bare band.
- Metal build Pentair lists the material as metal, so this is a steel band rather than a plastic clamp.
- Holds the tank together The band clamp is what keeps the two halves of the filter tank sealed against system pressure.
- Genuine Pentair Factory part 181011.
- Check the tank o-ring The matching 18 in. diameter tank o-ring is a separate part and is worth replacing whenever the clamp comes off.

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.
