This Hydrostream directional flow inlet fitting features a 1-inch opening designed to deliver balanced return water flow and pressure throughout your pool. The adjustable eyeball nozzle pivots easily within the 1.5-inch MIP threaded body, allowing you to aim the return stream precisely toward problem dead zones or surface skimmers to improve chemical distribution and filtration. Built from heavy-duty, UV-resistant thermoplastic, it provides long-lasting durability against harsh pool chemicals and daily wear.
