Pentair Volute O-Ring | Hydropump Pool Pump | 352626

Description

The Pentair Volute O-Ring (352626) is the OEM replacement volute O-ring for the Pentair Hydropump swimming pool pump.

IMPORTANT: LUBRICATION REQUIRED — SOLD SEPARATELY
Always lubricate this O-ring with a silicone-based lubricant before installation. We carry the Pentair R172351 Lifeguard Silicone Lubricant — the OEM-matched product for Pentair equipment.

This O-ring seals the volute housing of the Hydropump pump, preventing water from bypassing the pump chamber. A failed or degraded volute O-ring results in a visible leak at the pump housing joint and loss of system pressure.

Poolaroo Pro Tip

Before seating this O-ring, clean the volute groove thoroughly to remove any old O-ring material or debris. Apply a thin, even coat of silicone-based lubricant — we recommend the Pentair R172351 Lifeguard Silicone Lubricant — to help the O-ring seat correctly and extend its service life. Never use petroleum-based lubricants, which will degrade the rubber compound and cause premature failure.
