Does anybody know what brand fittings these are in my gunite spa? They seem pretty generic and there are no markings that I can see. The male threaded fitting in the photo has no notches for removal unlike the pool return fittings. I’m looking to replace some to have more variety.
Are there any other clues as to what that might be (air controls or any other jets)? It almost, but not quite, looks like this Waterway Power Storm jet…
