About This Item
The Pentair 274495Z is the OEM replacement O-ring for the Triton C TR100C and TR140C sand filters. This O-ring maintains the pressure integrity needed for proper backwash and filtration cycles.
⚠️ 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.
When this O-ring degrades, it can compromise the seal during operation. Replacing it restores a reliable seal and ensures the valve functions as intended. Match the part number on your existing O-ring before ordering — this listing is for the 3/16" x 2-5/8" inside diameter version.

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.
