About This Item

The Pentair Square O-Ring (Part #236950) is the OEM replacement square-profile O-ring for the Style I Floor Cleaning Head. Match part number 236950 to your existing component before ordering to confirm correct fitment.

⚠️ 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 square-profile O-ring seats within the Style I Floor Cleaning Head to maintain a sealed interface within the floor cleaning system. A damaged or degraded O-ring in this position can result in pressure loss and reduced cleaning performance. Replace this O-ring any time the head is disassembled for service or when leakage is observed at the head assembly.

O-Ring Profile Square
Quantity Included 1
Diameter 2-7/16in. 

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. Verify the square profile against your existing O-ring before ordering; a round-profile O-ring of similar size will not seal correctly in this application.

For the DIY homeowner, Pentair represents the intersection of rugged durability and silicon valley-tier technology. They pioneered the Variable Speed Pump revolution with the IntelliFlo®, saving American pool owners millions in energy costs. Today, their ecosystem focuses heavily on automation, allowing you to control your pump, heater, lights, and chemistry from a single app. While they are a favorite among professional builders, their "EC" (E-Commerce) line of equipment allows homeowners to access pro-grade technology with valid warranties for DIY installation.
