This is a genuine Waterway Old Style Adjustable Mini Jet Nozzle Insert featuring a 5/16 inch orifice size. Please note that only the nozzle insert is included—the jet face is sold separately and available through SpaShopper.

This nozzle insert is engineered to work exclusively with Waterway old style back neck jets that feature the distinctive 4-prong mounting system. The prongs on the jet face lock securely into the nozzle body for a stable, leak-free connection.

Installation Instructions: To remove your existing nozzle, carefully pry the jet face outward using a flat screwdriver, then unscrew the nozzle insert. For installation, position the new nozzle insert onto the prongs of your jet face and thread it clockwise until it stops. Avoid overtightening—simply rotate back slightly counterclockwise, then snap the face into place.

Compatibility Alert: Waterway manufactures two distinct nozzle styles (old and new), each available in two orifice sizes. This nozzle is designed specifically for the old style configuration with a 5/16 inch opening. Please verify your existing jet style before ordering to ensure proper fitment.

SpaShopper carries matching Waterway mini adjustable jet faces, o-ring kits, and installation tools for old style nozzles separately.
