Description

When performing leak testing, there is no room for error. Annotech's Leak Test Bladder is therefore designed to hermetically seal pipes, allowing you to perform pressure tests with peace of mind without risk of bladder displacement. The material effortlessly adapts to the unevenness of the pipe wall, whether PVC, concrete or vitrified clay.

Resistant to the Elements

In the sewer world, tools get tough. The G2 series is made of a rubber compound specifically selected for its resistance to sewage and light chemicals. In addition, the bladder remains operational in significant temperature fluctuations, which is critical for inspection services working outdoors year-round.

Technical Features & Functions

Feature	Specification / Description.
Maximum Working Pressure	1.5 Bar
Equipment	High-quality, flexible and chemical-resistant rubber
Application	Leak detection, pressure testing and temporary sealing
Compatibility	Suitable for various pipe diameters and materials
Connection	Robust air connection for easy inflation
Resistance	Wastewater, temperature changes and light chemicals

Why professionals choose the Annotech G2:

Safe Operation: Features a sturdy connection that prevents unintended deflation during testing.
Multi-purpose: One bladder can often be used for multiple pipe sizes thanks to the high elasticity of the rubber.
Longevity: The hard-wearing outer jacket resists the abrasive action of sand and deposits in sewers.

Expert tip: When inflating the bladder, always check that the inside of the pipe is free of sharp protrusions. Although the G2 is extremely rugged, a clean contact surface greatly extends the life of your rubber.
