Still Spirits EZ Inline Filter Large Cap

The large cap is the top closure of the EZ Inline Filter housing — it threads onto the housing to seal the filter and hold the cartridge firmly in place during filtration.

The cap also provides the spirit inlet — diluted spirit enters through the cap, flows down through the carbon cartridge inside, and exits filtered at the bottom.

A properly seated cap is essential for preventing leaks and ensuring all the spirit passes through the carbon rather than bypassing it.

If the cap thread strips, the cap cracks, or the seal starts to weep, replace it with this part.
