Pneumatic cone and wedge sealing lances and tank leak drainage bags for road tanker and rail wagon hazmat incidents. Authorised Vetter distributor — Africa & Gulf.

The Vetter leak sealing lance is a pneumatic device inserted into a leaking pipe opening, valve port, or small aperture and inflated to seal the leak from within. Available with cone, wedge, and multi-element heads to match different leak geometries. The complementary tank leak drainage bag system simultaneously seals the external surface of a tank leak and safely transfers the remaining hazardous product to a collection vessel.

Frequently Asked Questions

What is a Vetter leak sealing lance?

A Vetter leak sealing lance is a long pneumatic sealing element designed to be inserted into a pipe opening, valve port, or accessible aperture. Once inserted, it inflates to plug the opening from the inside — stopping the flow of liquid or gas. Lances are used where standard external sealing bags cannot access the leak geometry.

When is a tank drainage bag used instead of just sealing?

When a road tanker or rail wagon has suffered a structural failure, simply sealing the leak is not enough — the vehicle cannot be righted or moved until the remaining hazardous product is safely transferred out. The Vetter tank leak drainage bag seals the outside while a suction lance transfers product to a collection container, enabling safe vehicle recovery.
