3/4" MPT Flow Switch Assembly for Sundance Jacuzzi - Includes 3/4B x 3/4B x 3/8b Tee Housing

This flow switch assembly features a 3/4" threaded sensor with integrated housing designed for Jacuzzi Premium, Sundance Spas, and compatible hot tub brands. The included housing provides 3/4" Barb X 3/4" Barb X 3/8" Barb connections. Important: If your original housing lacks the 3/8" Barb connection, you'll need the alternate version without this port. Operates as a normally open switch that closes when water flow from your heating pump is detected. Equipped with box-style connector terminals compatible with Sentry 850 control systems, plus we provide 2 pinch-style connectors for compatibility with different wiring configurations. If your spa uses curly finger-style connectors typical of LX systems, please select the alternate version with those terminals. The 3/4" MPT threaded switch element can be unscrewed and transferred to a different housing if needed. Please Note: This modern housing replaces older PVC-construction housings found in vintage Sundance and Jacuzzi hot tubs. Before installation in an existing housing, verify thread size compatibility—some older flow switches used 1/2" MPT threads instead.
