Pair of 350mm/14 sewer and drainage air test pipe stoppers, each with an expansion range from 344-356mm, designed for use in a standard air pipe test of 100mm water over air.
Each air test stopper has both a blank and test end, allowing it to be used interchangeably on either end of the pipe being tested. The stoppers are 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.
Our sewer and drainage air test pipe stoppers are manufactured and tested to BSEN 1610 - 1998.
