The Pentair R301904 Lateral<\/strong> is the genuine OEM replacement lateral for 19″ Triton NEO sand filters. Laterals are the slotted plastic fingers mounted on the bottom manifold inside the filter tank. They allow filtered water to exit freely while preventing sand particles from passing through to the pool \u2014 making them one of the most critical components in any sand filter.<\/p>\n If you notice sand returning to the pool<\/strong>, the most common cause is a cracked or broken lateral. Replacing the damaged lateral \u2014 or the full set as a preventative measure \u2014 immediately resolves the problem and protects your pool equipment from sand damage. The R301904 is sold individually, allowing you to replace only the damaged unit without purchasing a complete set unnecessarily.<\/p>\n The lateral has an external diameter of 34 mm and a length of 130 mm<\/strong>, precision-moulded to the exact specifications of the Triton NEO 19″ manifold. The slot openings are sized to retain even the finest filtration sand grades.<\/p>\n The Pentair Triton NEO 19″ Lateral (R301904) is the original replacement lateral arm for Triton NEO 19″ sand filters. Laterals sit at the bottom of the filter tank and act as the final barrier, allowing clean, filtered water to pass through while retaining all sand inside the tank.
