Waterway 212-7639-STS Directional Power Storm 5"
Waterway has discontinued most of there snap in jets. This # 212-8059-STS will replace most of the snap in jets as long as the insert is identical. Jet internal measures 3 1/2" in length and 4 1/2" including the face.
So happy to have found a jet that works perfectly with our older tub. Easy to install!
Jet is a direct replacement. I would have liked a bigger selection as this directional jet was used to replace a spinner. Fits well.
