Replacement Hardware

Keep Every Filter Sealed Tight

Each filter is held in the upper chamber by a washer and a wing nut. The washer seals the filter to the chamber floor so water passes through the filter, not around it.

New Black Berkey elements come with this hardware. Order a set here to replace a worn or lost part, or to keep spares on hand.

Why Owners Order It

Key Benefits

Leak-Free Seal

A fresh washer seals the filter stem so only filtered water reaches the lower chamber.

Hand Tightens

The wing nut threads on by hand. No tools and no guesswork.

Fits Both Filters

Works with Black Berkey and Berkey Phoenix filters in your Berkey system.

How to Install

Seat, Insert, Hand Tighten

Take the upper chamber off the system and set it on a flat surface before you start.

  • Slide the washer onto the filter stem so it rests against the base of the filter
  • Insert the stem through the hole from inside the upper chamber
  • Thread the wing nut onto the stem from underneath
  • Hand tighten until snug, without overtightening
  • Fill the upper chamber and check for drips around each stem
Frequently Asked

Washer and Wing Nut Questions

Don't new filters come with washers and wing nuts?

Yes. New Black Berkey elements include 2 washers and 2 wing nuts. Order this set to replace a worn or lost part or to keep spares.

Will they fit Berkey Phoenix filters?

Yes. This set fits Black Berkey and Berkey Phoenix filters.

How many sets do I need?

One washer and one wing nut per filter. This set covers 2 filters, so order one set for each pair of filters you need to replace hardware on.

When should I replace them?

When a washer looks flattened, cracked or stiff, when a wing nut is cracked or won’t hold, or when you see drips around a filter stem.

Why is water leaking around my filter?

Check that the washer sits flat against the base of the filter and the wing nut is snug. Hand tighten only, since overtightening can bend the washer. If the washer is worn, replace it.
