The Pentair 178575 Bottom Bulkhead is a factory-original replacement fitting engineered for Pentair Quad DE, Clean & Clear Plus, and FNS Plus filter systems. As a key structural connection point, this bulkhead preserves the integrity of the filter housing and ensures water passes through the system without leakage. Manufactured to Pentair's original design specifications, it sustains steady water flow and promotes efficient filtration under normal operating pressures. Built from resilient, pool-rated materials, it handles the rigors of daily pool and spa operation with ease. Replacing a compromised bulkhead with this OEM part ensures that your filter continues to deliver balanced, clean water.

Key Benefits
