Pneumatic Sealing Suction Cup
A vacuum suction cup that seals leaks on tanks and containers and drains hazardous liquid under control — no tensioning straps required.
Seal & Drain Tank Leaks Under Control
Suitable for oil tankers, liquid tank trucks, large containers and oil storage tanks, the suction cup creates a vacuum seal over the leak site while allowing liquid to drain through a discharge chamber — enabling the controlled drainage of hazardous substances.
- No straps — the 200 mm circular pad forms a vacuum seal by itself
- Controlled drainage — discharge chamber allows safe removal of hazardous liquid
- Robust build — compact vacuum nozzle and high-quality steel connectors
- Optimal efficiency — 200 mm diameter ensures efficient drainage
