Currently, the Union O-Ring is the only part available for a Union filter in 1-1/2” and 2”.

If a single piece needs to be replaced, the whole Union must be purchased.

Aqua Ultraviolet is dedicated to keeping your filters working at peak performance. If you need a 1-1/2” or 2” Union for a new filter or as a replacement for an older Union, Aqua Ultraviolet is proud to provide for you.
