Rising Dragon RD50 filter adapter

This adaptor converts from the original screw-in type filters to the filters with a hole straight through. It allows you to use a PRB50 or PRB25-type filter cartridge, which are very common, inexpensive and are sold by several different brands, instead of the RD50 filter that was delivered with your spa.

The adapter fits inside the central column of your PRB50 filter. It has an female threaded opening at the bottom and a handle at the top, just like the RD50.

Please note that this adapter is not compatible with Claralys CRB50 and CRB25 filters.
