About This Item
The Pentair 3-Port Valve Compression O-Ring (071427Z) is the OEM replacement compression O-ring for Pentair 3-port valves, providing the sealing interface that prevents water bypass at the valve compression point.
⚠️ 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 compression O-ring seats within the 3-port valve body to maintain a watertight seal under normal operating pressure. When this O-ring wears, flattens, or takes a compression set, the valve can develop internal leaks or lose diverting efficiency. Replacing it restores the valve's sealing integrity. Match the part number 071427Z to the number on your existing O-ring or your valve's parts diagram before ordering.

Pro Tip
Before installation, apply a thin coat of Pentair R172351 Lifeguard® Silicone Lubricant to the O-ring. This helps the O-ring seat evenly in its groove, prevents tearing during assembly, and extends service life. Never use petroleum-based lubricants — they will degrade the rubber compound and accelerate failure. The #2-259 designation is a standard O-ring sizing reference — confirm this designation matches the marking on your original part before ordering.
