Product Overview

The Pentair 181011 Nautilus NS tank clamp assembly is a structural component used to secure the two halves of a Nautilus stainless steel D.E. filter tank. The clamp band wraps around the joint between the tank sections and tightens to create a strong mechanical connection that keeps the filter housing sealed during pressurized operation.

The assembly includes the clamp band halves along with springs, nuts, and washers that allow the clamp to be tightened evenly around the tank seam. This design helps maintain consistent pressure sealing while still allowing the filter to be opened when maintenance or internal component servicing is required. Replacing a worn or damaged clamp assembly restores proper tank sealing and ensures safe, reliable operation of Nautilus NS filtration systems.
