Individual 850mm/34” sewer and drainage air test pipe stopper, with an expansion range from 844-856mm, designed for use in a standard air pipe test of 100mm water over air.

This single air test stopper has both a blank and test end, allowing it to be used on either end of the pipe being tested. The stopper is inflated using a ¼” Schrader valve, and can be deflated using a pull tag on the surface, collapsing into an easily transportable and lightweight shape. The stopper is fitted with handles on either side to assist with positioning and removal.
Our sewer and drainage air test pipe stoppers are manufactured and tested to BSEN 1610 - 1998.
