Pentair Triton II Lid Closure

No, this specific part number (154559) is designed exclusively for the Pentair Triton II TR100 and TR140 sand filter models. It will not fit other Triton series filters, so please verify your filter model number before purchasing.

This is a 6-inch lid closure, designed specifically to fit the 6-inch opening on compatible Triton II filter tanks.

Using a genuine Pentair part ensures the exact tolerances and material quality required for a high-pressure pool filtration system. Aftermarket alternatives may not provide the precise seal needed to prevent leaks or withstand the operating pressure of your filter.

You should consider replacing the closure if you notice visible cracks, warping, or if the threads are stripped and no longer provide a secure, tight seal. If you are experiencing persistent leaks around the filter lid despite tightening, the closure is likely compromised and needs to be swapped.

This product is the lid closure itself. It does not include the O-ring or gasket, so you may want to inspect your existing O-ring for wear and replace it separately if it has become brittle or flattened.
