Product Overview

The Pentair 194997 machined clamp nut is an important fastening component used in Pentair FNS and FNS Plus vertical grid D.E. filtration systems. Installed on the clamp bolt of the tank band clamp assembly, the nut provides the tightening force required to hold the upper and lower filter tank sections securely together.

Maintaining proper clamp tension is essential for keeping the filter housing sealed under pressure during normal operation. Over time, clamp hardware may wear or corrode due to environmental exposure and repeated maintenance cycles. Replacing the clamp nut restores secure tightening capability and helps ensure reliable sealing and safe operation of the filter system.
