About This Item
The Pentair 35505-1318Z is the OEM replacement O-ring for the Sta-Rite Plastic Slide Valve, serving as the primary sealing element that keeps the valve watertight under operating pressure.
⚠️ 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 seats within the Sta-Rite Plastic Slide Valve body to create a pressure-tight seal between moving valve components. When the O-ring wears, cracks, or deforms, the valve develops leaks at the slide interface — replacing it restores a proper seal and prevents water loss or pressure drop at the valve. Match the part number stamped or molded on your existing O-ring before ordering to confirm this is the correct size for your valve.

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 and cause premature failure.
