SES1.5 1.5" Steel Expanding Pipe Stoppers

SES1.5 Steel Expanding Pipe Stopper is a robust, expandable test plug designed for temporary sealing of pipe ends in demanding welding, fabrication, and industrial piping applications. Constructed from steel with a natural rubber tyre for enhanced durability, this lightweight tool effectively blocks water, gases, and debris during installation, repairs, or testing, fitting pipes with internal diameters from 1.46" to 1.97" (37-50 mm, 1.5" nominal). Ideal for arduous duties like prolonged immersion, elevated temperatures, or contact with acidic/alkaline environments, it conforms to British Standard BS8005 for low-pressure testing and sealing.
