The 25053-WH jet is a component manufactured by G & G Industries, which has since been consolidated under the Balboa Water Group (BWG) brand.
This part, a G&G Trans-Adjustable Directional Jet Internal with a Star Grip in white, is used in hot tubs by a variety of manufacturers who incorporate standardized components from major suppliers.
Manufacturers known to use Balboa Water Group (and formerly G&G Industries) components include:
Superior Spas
H2O Spas
Platinum Spas
Bullfrog Spas (for their general electronics, not their proprietary JetPak system)
Cal Spas
Master Spas
Coast Spas
Marquis Spas
Hydropool
Emerald Spas (and others that use CMP Typhoon jets, a line also related to BWG)
Due to the standardization of parts in the industry, the specific jet might appear in many other brands and models.
