    Reliably seal leaks and safely drain hazardous substances with the acid drain hose. Vetter leak drainage bags are the ideal solution when substances cannot be drained via the normal opening, or if this can only be done with considerable technical effort, e.g. in the case of high-up discharge openings on tanks or a pump failure. As Vetter leak drainage bags are tensioned with belts, they can be used on many kinds of surfaces. The bags are quick and easy to inflate using a foot pump. Only a few strokes of the pump are required to seal the leak.

    Perfect fit for safe drainage at flanges.
    Problems with leaky pipe connections? Make the task of sealing difficult leaks on all types of flanges easier for your team. Flanges are critical pipe sections and conventional sealing bags will rarely be effective here. Vetter flange drain bags cover the flange and pipe, reliably stop the leakage of hazardous liquids and at the same time allow you to drain off the liquid in a controlled and safe manner. The bags come in three sizes to cover all customary pipelines and flanges. Gel plates are included for convenient smoothing out of minor irregularities and unevenness on the pipe’s surface.It couldn’t be simpler:
    Place the bag around the flange and pipe, close the zip fastener along the entire length of the bag and inflate the sleeves. Immediately, everything is sealed and you can commence with controlled drainage of the liquid.
