Xylem-Bell & Gossett 113252 Air Vent Cap

The Xylem-Bell & Gossett 113252 Air Vent Cap is a small sealing and flow-control component used in hydronic equipment to cover and regulate the air vent opening. It control the release of trapped air from the system by allowing air to escape while limiting unwanted leakage of fluid from the vent assembly. The cap is designed to fit securely on the vent body and maintain proper venting operation under normal pressure conditions. In HVAC systems such as boilers, hydronic heating loops, and pumping assemblies, it contributes to air removal within the circulation circuit. Positioned at the vent outlet, it supports controlled air discharge from the connected piping network.
