About This Item
The Pentair O-Ring, Round (U9-228AZ) is the OEM replacement round O-ring for Pentair IntelliPro variable speed pumps and Max-E-Pro inground pumps.
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.
IMPORTANT: MODEL YEAR VARIANT
The fit note for the IntelliPro Variable Speed Pump (INTELLIPRO) specifies units manufactured before 2019. If your IntelliPro pump was manufactured in 2019 or later, verify this part number against your equipment manual or the original O-ring before ordering.
This round O-ring maintains a watertight seal within the pump assembly. A worn or damaged O-ring can allow water to bypass the seal, leading to leaks at the pump body and potential motor damage.

Pro Tip
Before seating the O-ring, apply a thin, even coat of Pentair R172351 Lifeguard Silicone Lubricant to help the O-ring seat fully and resist compression set over time. Avoid petroleum-based lubricants — they degrade rubber O-rings and will shorten the service life of the new part.
