SES6 6" Steel Expanding Pipe Stoppers

SES6 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 5.74" to 6.61" (146-168 mm, 6" nominal). Ideal for heavy-duty applications like prolonged immersion, elevated temperatures up to 194°F (90°C), or contact with acidic/alkaline environments, it conforms to British Standard BS8005 for low-pressure testing and sealing.
