Test Pipe Sealing Cushions

Premium Flow-Trough Plugs

The Cherne i2 series premium flow-through plugs with bypass are used for both testing and monitoring of private and municipal piping systems. The premium components used, such as Nitto quality fittings, a solid body cord and aluminium end plates, ensure maximum stability and durability. The short, lightweight design makes these pipe plugs particularly easy to transport and install, even in the tightest of spaces.

The rubber body of the Cherne i2 is made of tear-resistant natural rubber. The mechanical connection between the rubber body and metal plates provides additional holding power. Our flexible Cherne premium flow-through plugs are available in various dimensions from 100 – 1500 mm, on request also with a male quick coupling connection or a Schrader valve.
