About this model

Short Description / Summary A heavy-duty, fluid-optimized 1-to-4 splitter manifold designed for submerged, high-pressure water applications. Engineered to handle high-flow submersible trash pumps (up to 1 HP / 5000 GPH) with minimal turbulence. Perfect for custom pond aeration systems, aquaponics, or pool/spa bypass loops. Full Description Welcome to another functional, engineering-grade design from Torque Joint Labs. This manifold was mathematically modeled in Autodesk Fusion 360 to smoothly transition a massive volume of water from a single 3-inch pipe into four 1.5-inch branches. It eliminates the sharp, asymmetrical internal corners found in standard PVC fittings to minimize fluid turbulence, reduce pump backpressure, and perfectly balance flow distribution across all four nozzles.
