The Pentair LF24 Backup Extension O-Ring is a critical sealing component used in Sweep® I and II in-floor pool cleaning systems. This O-ring fits snugly within the backup extension assembly, forming a tight barrier that prevents water from leaking at key connection points inside the valve body.

A compromised O-ring can lead to reduced system pressure, cleaning inefficiency, and increased wear on internal parts. The LF24 is made from high-performance rubber, engineered to resist pool chemicals, heat, and daily water flow stress — ensuring long-lasting reliability even under tough conditions.

Whether you're completing a full valve rebuild or addressing an isolated leak, the LF24 is a go-to replacement part that restores integrity and supports optimal operation in your in-floor cleaning system. Its precise fit makes installation simple for both service professionals and DIY pool owners.
