Pentair  Sweep® I/II O-Ring – Replacement for Valve Housing

Pentair LG12 O-Ring for Sweep I/II in-floor systems. Creates a watertight seal between valve shells to prevent leaks and maintain pressure.

• Engineered for Sweep® I & II Systems – Forms a pressure-tight seal between top and bottom valve shells.

• Prevents Leaks & Pressure Loss – Maintains optimal in-floor cleaning system performance.

• Durable, Chlorine-Resistant Material – Designed for longevity in chemically treated pool environments.

• Essential for Valve Maintenance – Replace during rebuilds or whenever sealing issues arise.

• OEM-Compatible Fit – Matches original part specifications for a secure and lasting seal.

The Pentair LG12 Sweep® I/II O-Ring is a critical sealing component used in the Sweep® I and II in-floor valve systems. Positioned between the upper and lower housing shells, this O-ring ensures a watertight, pressure-resistant seal that prevents leaks and maintains the internal flow required for efficient cleaning cycles.

Made from a high-grade, chemical-resistant elastomer, the LG12 withstands prolonged exposure to chlorinated water, high-pressure flow, and UV light without degrading. Over time, O-rings may flatten, crack, or lose elasticity—causing pressure drops, water seepage, or internal damage to the valve mechanism.

Whether you’re rebuilding a worn valve or troubleshooting performance issues, replacing the O-ring with a genuine LG12 ensures your system stays sealed and operating at full capacity. This is an essential part for any service technician or pool owner maintaining a reliable in-floor cleaning setup.
