Pentair 155738z Closure Kit 8.5 Inches Triton Ii Filter

Product Description

The PENTAIR 155738z is a heavy-duty closure kit designed to provide a secure, leak-resistant seal on Triton II side-mount pool filtration systems. At 8.5 inches in diameter, this closure kit maintains the pressure integrity of the filter tank, preventing bypass and protecting internal filter media. It is installed by pool service professionals and licensed pool technicians during routine maintenance, filter media replacement, or after tank inspection. The heavy-duty construction is suited for the demands of residential and light commercial pool systems where reliable sealing is critical to system performance.

This closure kit is intended for use with the Pentair Triton II Side-Entry (S.I.D.E.) mount filter, specifically the TR60 2 configuration with no valve. It is used in pool filtration applications where the tank must be opened for service and then resealed to return the system to full operating pressure. The 8.5-inch diameter matches the tank opening on applicable Triton II filter models, making it a direct-fit service replacement for that platform.

Installation Notes

Installation is typically performed by a licensed pool service technician. Before servicing the filter tank, shut off the pool pump and relieve all system pressure at the pressure relief valve before removing the closure. Ensure the mating tank surface and any sealing surfaces are clean and free of debris before seating the closure kit. Follow all applicable local codes and the filter manufacturer's service documentation when reassembling pressurized pool equipment.
