Pentair Rubber Pump Base Pad | MPR, P4R, P4E, TPR, TPE | 17350-0008 Filter Cartridges Replaceable snap-on frame and netThe Pentair Rubber Pump Base Pad (17350 0008) is the OEM replacement noise reducing base pad for Pentair MPR, P4R, P4E, TPR, and TPE series spa and water feature pumps. This rubber pad mounts beneath the pump housing to absorb vibration and dampen operational noise at the base. Without it, direct contact between the pump and its mounting surface transmits motor vibration, increasing noise levels and accelerating wear on mounting hardware over time.
