Description
Waterway Power Storm Internal Twirl 5-Point Scalloped in Black (212-7639-STS) is a purpose-built replacement that revives the distinctive hydro-massage swirl your spa relies on. This internal jet insert replaces the older 212-7641 part while preserving the same trusted Power Storm performance, so you can restore comfort and circulation without a full jet retrofit. Designed for dependable spa performance, the Twirl nozzle delivers a focused, spiral massage that enhances hydrotherapy without creating harsh jets or uneven flow. The 5-point scalloped outlet geometry creates a balanced spray pattern, promoting smoother water flow and more even coverage across your spa seats. Built for durability in hot tub environments, the high-strength black polymer resists the chemicals, heat, and UV exposure common in pool and spa settings. Key features
