Description
The Pentair Diffuser Assembly TR140 (SKU 154906) is a vital internal component for the Triton II TR140 fiberglass sand filter. It directs water evenly into the sand bed, preventing uneven flow paths that degrade filtration. Over time, diffusers may degrade due to pressure, debris, or aging. This genuine OEM diffuser is engineered for durability in challenging pool environments, helping maintain optimal filtration and preserving other filter components from stress.
Pro Tip
Rinse the diffuser before installation to remove loose particles. Consider replacing the closure O-ring (e.g. Pentair 154493) at the same time to ensure a tight, leak-free seal.
