HydroAir – Eyeball Jet for Concrete Spa Wall Fitting

The Balboa / HydroAir Eyeball jet, part number 50-3420 (also listed as 10-3420), is a replacement hot tub jet for concrete spas. It is installed directly on a wall fitting and gives a fairly broad, pleasant massage of the back. Its key feature is this direct fit onto the wall feed-through used in concrete spa construction.

Eyeball jet 50-3420 compatibility

This spa jet is made for concrete spas. It is installed directly on a wall fitting, so it is the right choice when your concrete spa already has this type of fitting in the wall.

Balboa / HydroAir lists the jet under two part numbers: 50-3420 and 10-3420. Search for either number when you compare it with the jet you want to replace.

Massage and use

The Eyeball jet delivers a fairly broad and pleasant massage of the back. If you are replacing a jet of this type in your concrete spa, it keeps the same style of massage.

Dimensions and fitting

• Face diameter: 67 mm
• Outside diameter of the spigot that is inserted in the wall fitting: 40 mm

Before ordering, measure the visible face of your current jet and the spigot that goes into the wall fitting. Both measurements should match the figures above.

How to choose the right jet

Check the part number on your existing jet, or in your spa documentation, and compare it with 50-3420 or 10-3420. This replacement jet is intended for a wall fitting in a concrete spa, so check what type of fitting your spa has.
