Retailer ratings2.6 · 5 ratingsOne of these is on the shelf, waiting its turn in the inspection queue. That price is the most it will list at, never more. Anything we find comes off it. An inspection can also find a unit we will not sell, and then this one never goes on sale.

We move it to the top of the inspection queue and email you the results, usually within a few hours.
Nothing is held for you. When it goes on sale the first person to check out gets it, and emailing you first is the head start.

About this item
This lock nut assembly is intended for use with ClearWater II cartridge and D.E. filters, serving as a direct replacement for worn or cracked original locknuts. It is built from plastic and finished in black, with external locking tabs designed to hold the filter lid assembly secure against the filter body.
The part is sized for an 8 inch groove diameter and uses a Unified National Coarse thread in a right-hand, coarse configuration with a round screw head style. It is rated for commercial use and intended to withstand outdoor exposure.
Installation involves loosening the external locking tabs, turning the assembly counterclockwise to remove the old unit, then fitting the new one back into place and resecuring the tabs, without requiring additional tools.
