About This Item
The Pentair 154005Z is the OEM replacement Parker 2-343 O-ring for the Triton C-3 sand filter series. If a sealed joint on your Triton C-3 is weeping or leaking, this is the correct O-ring to restore a pressure-tight seal.
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: 2 O-RINGS REQUIRED PER FILTER
Two of these O-rings are required per Triton C-3 unit for a complete service. This listing is sold individually (each). Order 2 to complete the job.
This O-ring seats at its designated joint on the Triton C-3 sand filter housing, maintaining a pressure-tight seal during normal filter operation. A degraded or displaced O-ring at this location allows water to bypass the seal, resulting in visible leakage at the filter. Replacing this O-ring at the first sign of weeping or dripping restores the seal and prevents water loss or pressure drop.

Pro Tip
Before installation, apply a thin, even coat of Pentair R172351 Lifeguard Silicone Lubricant to the O-ring. This helps seat it evenly in the groove, prevents tearing during assembly, and extends service life. Never use petroleum-based lubricants — they will degrade the rubber compound and cause premature failure. Remember: 2 of these O-rings are required per filter — confirm your quantity before ordering. Verify the Parker 2-343 designation against the part number stamped on your original O-ring or shown in your filter's parts diagram.
