AES1.5 1.5" Aluminium Expanding Pipe Stoppers

AES1.5 Aluminium Expanding Pipe Stopper is a durable, expandable test plug designed for temporary sealing of pipe ends in welding, fabrication, and industrial piping applications. Made from aluminium with a natural rubber tyre, this lightweight tool effectively blocks water, gases, and debris ingress during installation, repairs, or testing, fitting pipes with internal diameters from 38mm to 50mm (1.5" nominal). Ideal for arduous duties like chemical immersion or higher temperatures, it conforms to British Standard BS8005 for low-pressure testing and sealing.
