Description
Caleffi North America 535056A is an AutoFill™ assembly with 3/4 in. union press connections and a pressure gauge.
AutoFill valves are used to fill a hydronic heating system and keep its pressure up, and the included gauge lets you read system pressure at the fill point.
The connections are press, so you need a compatible press tool and tubing. Confirm the 3/4 in. size against your piping, and review the data sheet, installation manual and submittal below before ordering.
