Part number 229-8057 is the gray version of the Waterway Poly Storm Gunite jet internal. It is functionally identical to the black 229-8051 but features a 3-3/8" gray textured 5-scallop face.
Because it belongs to the standard Waterway "Storm" series used for high-performance hydrotherapy, this part is used by a similar group of manufacturers as the 229-8051, including:
Artesian Spas: A major user of the Waterway Poly Storm series for their standard jet configurations.
Clearwater Spas: Often utilizes this gray variant for models with light-colored acrylic shells or gray cabinet designs.
Cal Spas: Frequently uses both the snap-in and thread-in versions of these Waterway internals.
Viking Spas: Uses the Poly Storm thread-in series as a primary jet option in their portable spa lineup.
Strong Spas: Incorporates Waterway-manufactured jet assemblies across their diverse spa lines.
Custom Concrete (Gunite) Spas: This specific "Gunite" version is the standard for custom-built concrete hot tubs and spas where jets are threaded into wall-mounted bodies.
