About This Item

OEM Replacement O-Ring for the Pentair C Series® C-70 Pump

The Pentair 071423Z is the OEM replacement O-ring for the C Series® Model C-70 pump. If your pump is showing signs of leakage at a sealed joint or housing interface, this is the correct factory-spec O-ring to restore a proper 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.

This O-ring seats within the C-70 pump assembly to maintain a watertight seal at its designated joint. A degraded or cracked O-ring at this location allows water to bypass the seal, which can lead to visible leakage, loss of prime, or water intrusion into areas of the pump where it should not reach. Replacing it with the correct OEM part ensures the proper fit, compression, and material compatibility required for reliable long-term sealing.

Quantity Included 1 (Each)

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. Match the part number on your existing O-ring or in your C-70 pump's parts diagram before ordering to confirm this is the correct ring for your specific seal location.
