ProLine 1/2" brass MPT boiler drain is designed for draining water from boilers and releasing accumulated sediment. It features multiple connection options, including 1/2" external MPTs, a 1/2" internal solder connection, and a 3/4" male hose thread outlet that is compatible with standard garden hoses. The multi-turn cast iron handle allows for precise flow adjustment or direct shut-off. Suitable for both iron pipe and copper inlet types, this durable, corrosion-resistant brass boiler drain is ideal for non-potable water applications.
