E700-PJ

ASD Pipe Joiner is a straight coupling that connects two pieces of 25 mm ASD pipe in a continuous, airtight line. It’s used when a pipe run needs to be extended, repaired, or joined after cutting. Its role is simple but vital—it ensures that airflow between pipe segments remains sealed and uninterrupted.
