Pentair LF12 Float Arm Grommet – Replacement Seal for Sweep® I & II Pool Cleaner Float Arms

• Fits Sweep® I and II In-Floor Systems – Designed to seal the connection point of the float arm to maintain pressure balance.

• Prevents Leaks and Air Intrusion – Keeps system airtight and operating at peak efficiency.

• Durable Rubber Construction – Built to withstand exposure to pool chemicals, water pressure, and UV rays.

• Small Part, Big Impact – Critical for cleaner performance and system longevity.

• Quick Installation – Simple to replace during float arm or hose servicing.

The Pentair LF12 Float Arm Grommet is a small but essential component that helps keep your Sweep® I or II in-floor pool cleaning system sealed and functioning properly. Positioned at the float arm connection point, this grommet forms a watertight seal that prevents leaks and ensures stable pressure inside the cleaning unit.

Over time, grommets can degrade from chemical exposure, temperature changes, or wear and tear—leading to air leaks, loss of efficiency, or erratic cleaner behavior. Replacing a worn LF12 is a quick fix that restores smooth float arm movement and protects the overall system.

Made from durable, pool-grade rubber, the LF12 is resistant to chlorinated water and sunlight, ensuring long-term reliability even in demanding conditions. It installs easily and should be checked regularly during float arm maintenance or troubleshooting.

If you're seeing water leaks or float instability, this OEM replacement grommet helps seal the system back to factory performance.
