About This Item
The Pentair O-Ring 2-248 Buna-N 70 Shore A (270116Z) is the OEM replacement O-ring for the FULLFLOXF® Diverter & Check Valve assembly — specifically the 3-way solar diverter valve with drain-down check valve.
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 Buna-N compound O-ring at 70 Shore A durometer maintains a pressure-tight seal within the FULLFLOXF® diverter valve body. A failed or degraded O-ring in this position results in internal valve leakage or loss of flow control between the diverter and check valve sections — making this a direct-replacement service part when the valve develops a bypass or weep.

Poolaroo Pro Tip
Before seating this O-ring, apply a thin, even coat of silicone-based lubricant — never petroleum-based products, which degrade Buna-N rubber and void the seal. We recommend the Pentair R172351 Lifeguard Silicone Lubricant for OEM-compatible lubrication. Inspect the O-ring groove for debris or scoring before installation — a clean seating surface is essential for a leak-free result.
