2.5 Inflatable pipe stoppers are used to seal a wide a range of pipes from concrete and clay to plastic and ductile iron.

Ideally suited for circumstances where back-pressures or flow rates are present up to 1 bar (10m Head of Water - 0.97 Atmospheres ref subsea use). All 2.5 Bar blank inflatable pipe stoppers are fitted with a series 26 coupling.

Caution: Suitable bracing & precautions should be used with inflatable pipe stoppers at all times. Back pressure values are valid in concrete pipes and properly braced or supported configurations.

Our blank inflatable pipe stoppers are manufactured from natural rubber and available to buy online, all of our inflatable stoppers can be manufactured to order in a nitrile or neoprene finish - please contact us for a quotation if you would like the stopper to incorporate either of these finishes.
