This Hydrostream directional flow inlet fitting features a 3/4-inch opening to control and increase return water velocity back into your pool. The adjustable eyeball nozzle pivots within the 1.5-inch MIP threaded body, allowing you to direct water flow toward surface skimmers or problem dead spots to optimize chemical dispersion and filtration. Molded from durable, UV-resistant thermoplastic, it provides long-lasting resistance against harsh pool chemicals and daily wear.
