Why CHERNE test balls?
The CHERNE test ball is a pneumatic shut-off bladder that is inflated through a tire valve and seals firmly against the pipe wall. The ball shape provides a secure hold even in short pipe sections and bends. The chain and ring are the practical advantage in everyday work: they secure the bladder against slipping and let you simply pull it back out once the job is done. The multi-size test balls are particularly flexible, covering a whole size range and thus replacing several individual bladders.
CHERNE or a Drexl shut-off bladder?
If you are specifically looking for the CHERNE brand, you are in the right place. If instead you need a solution for larger diameters or our own short and long variants, you will find these among our shut-off bladders. For standard-compliant testing tasks, it is also worth looking at our test bladders with bypass.
Frequently asked questions about CHERNE test balls
What is a CHERNE test ball?
A CHERNE test ball is a pneumatic shut-off bladder with a ball shape, fitted with a chain and ring. It is inserted into the pipe, inflated and seals the line, for example to shut it off or for a tightness test.
What does multi-size mean for the test balls?
A multi-size test ball covers a whole diameter range, for example 100 to 150 mm, rather than a single fixed size. This means one bladder replaces several individual models and can be used flexibly for different pipe sizes.
What are the chain and ring for?
The chain and ring secure the test ball against slipping inside the pipe and allow you to pull the bladder back out in a controlled way after use.
Which sizes are available?
We stock CHERNE test balls for pipe sizes from around 20 to 150 mm, both as single sizes and as variable multi-size models.
