About This Item

The Pentair 14971-SM10E10 is the OEM replacement O-ring for the Sta-Rite Side Mount Multiport Valve in 1-1/2" and 2" configurations.

⚠️ 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 Sta-Rite Side Mount Multiport Valve, preventing water from bypassing the valve body. A deteriorated or flattened O-ring allows water to leak around the valve assembly, reducing valve performance and potentially causing water loss at the valve body. Replacing this O-ring restores a proper seal and is a standard service item whenever the valve is disassembled for internal maintenance.

Compatibility is based on Pentair parts documentation and available OEM records. This is not an exhaustive list. For certainty, verify the part number in your equipment's manual or on the original part itself before ordering.

Pro Tip

Before installation, apply a thin coat of Pentair R172351 Lifeguard® Silicone Lubricant to the O-ring. This helps seat it evenly, prevents tearing during assembly, and extends service life. Never use petroleum-based lubricants. They will degrade rubber O-rings. While the valve is open for service, inspect the rotor and spider gasket for wear; replacing worn internal components at the same time avoids a repeat disassembly.
