Product Overview

The Pentair 25021-0003 air bleed tube is an essential component of the air relief system used in Sta-Rite System 3 filtration systems. Installed inside the filter housing, the tube provides a pathway for trapped air to escape from the filtration chamber.

Air accumulation inside a filter tank can disrupt water circulation and cause unstable pressure readings. The air bleed tube works with the filter’s air relief valve to release trapped air and maintain consistent filtration performance. Replacing a worn or damaged air bleed tube restores proper air venting and ensures reliable operation of the Sta-Rite System 3 pool filtration system.
