Pentair Hub Lateral | Triton II Sand Filter | 154763Z

Description

The Pentair Hub Lateral (154763Z) is the OEM replacement hub lateral for the Triton II Sand Filter, fitting models TR40, TR50, and TR60.

What It Does

The hub lateral anchors the lateral arms at the base of the sand filter’s underdrain system. It collects and channels filtered water from the laterals into the return line while keeping sand contained within the tank. A cracked or broken hub allows sand to bypass the laterals and enter the pool return lines — replacing it restores proper filtration and eliminates sand contamination.

Specifications

Fits Into

Compatibility is based on Pentair parts documentation and available OEM records. This is not an exhaustive list. For certainty, verify the part number in your equipment’s manual or on the original part itself before ordering.

Pro Tip

When replacing the hub lateral, inspect all lateral arms at the same time — they are subject to the same mechanical stress and age at the same rate. Replacing a cracked lateral alongside the hub in a single service visit avoids reopening the filter tank for a follow-up repair shortly after. Match the part number molded or stamped on your existing hub to 154763Z before ordering to confirm fitment.
