CO2Art Washer Replacement Kit for PRO-Series

CO2Art Washer Replacement Kit for PRO-Series Regulators – Pack of 3

The CO2Art Washer Replacement Kit includes 3 replacement washers designed for CO2Art PRO-SE and PRO-ELITE Series CO₂ regulators.

These washers sit between the CO₂ cylinder and regulator, helping create a tight, leak-free seal when connecting your regulator to a CO₂ bottle. Replacing worn washers helps maintain proper pressure and prevents CO₂ leaks.

A simple spare part that’s always good to keep on hand when running a CO₂ system on a planted aquarium.
