Popular Rainbow RTL Filter Assembly. Includes all shown components, plus a new filter cartridge. 1.5 or 2.0" PVC slip fittings. Used in thousands of spas and many different spa and hot tub brands. By Rainbow Plastics. If you are replacing this filter, we reccomend replacement with the waterway top load filter. It is the same size and configuration.
Thousands of spas have used this filter cannister, notably Cal Spas, Leisure Bay, Morgan and many others. Some will be tan in color, with dark lock rings. The latest production as you see in the photo is white. The tan versions are no longer made, but the functionality of the newer white cannister is exactly the same.
We recommend our stock Waterway brand cannister assembly to replace it.
