Pentair 1.25" Triton TR100/TR140 Lateral Hub Assembly

The Pentair 1.25" Triton TR100/TR140 Lateral Hub Assembly (part number 154453Z) is a crucial core plumbing manifold situated at the absolute bottom of Pentair Triton II, Triton C, and Triton C-3 high-capacity commercial and residential sand filtration systems. Injection-molded from a dense, heavy-duty thermoplastic composite, this central distributor hub anchors the internal underdrain grid by featuring specialized female threaded receivers engineered to accept the filter’s eight radiating lateral arms. Its primary structural role is to channel the fully filtered water out of the sand media bed and upward through the main standpipe while simultaneously preventing fine filter sand from escaping back into the pool. Built to withstand continuous hydraulic pressures, internal shifting forces from backwash cycles, and relentless exposure to chlorinated water, this robust manifold assembly provides years of rigid, structural underwater support. Despite its tough, heavy-walled construction, the compact hub assembly is lightweight and easy to manage during deep-tank repairs, carrying an actual product and shipping weight of approximately 0.80 pounds (or about 12 ounces).
