The top cap is a cover piece that sits on the upper part of a boiler or burner assembly. It protects internal components from debris and accidental contact while also contributing to the appliance's insulation. This cap is designed to fit specific models and is made from durable materials. Replacing a missing or damaged top cap helps maintain the integrity of your heating equipment and ensures safe operation. It is a simple but important spare part for boiler maintenance.
