Frequently Asked Questions

What is the difference between Test Ball and Muni Ball plugs?

Test Ball plugs do not feature a bypass and can only block (seal) a pipe. A Muni Ball plug, on the other hand, features a bypass tube running through the plug to bypass effluent through the tube. It can be converted for air testing using an adapter cap and can also block a pipe.

What materials are used to make Cherne pneumatic plugs?

Most of Cherne's pneumatic plugs have natural rubber construction. Only yellow pillow plugs are made from polyurethane impregnated fabric.

What are the operating temperatures of a Cherne pneumatic pipe plug?

Cherne pneumatic pipe plugs can operate in temperatures ranging from 0 to 125 degrees F.

How do I use Cherne plugs?

  • Determine the correct size of the Cherne plug for the pipe you're working with.
  • Clean the area around the pipe where the plug will be inserted.
  • Apply lubricant to the gasket on the plug.
