Rick. This Eyeball Seat has a 1-14/16" diameter on one end and 2" diameter on the other.

Should this type of fitting be used for a spa jet? My pool was resurfaced a few years ago and the wall fittings were replaced with these. With the eyeballs installed the blower is not able force air into the line and water starts to pressurize the air line. The jet orifices are ~18-20 inches from the face of the spa wall.

Hi, Sam. These types of Inlet Eyeball Fittings can be used in a spa with the proper jet body and air to water mixture is correct to the amount of jets.
