CHERNE Plumbing Test Ball Plugs, Single Size

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

• A Test Ball does not have a bypass and is only intended to block (seal) a pipe.
• A Muni Ball has a bypass tube that runs through the plug, allowing the user to bypass effluent through the tube or complete an air test with an adapter cap.
• Muni Balls can also be used to obstruct pipes.

How to install Cherne Test-Ball plugs?

• Place the plug in the pipe or application to be blocked or tested, making sure it is at least as long as the pipe diameter.
• Connect one end of the inflation hose to a plug inflation fitting (such as a Schrader valve, 1/4, 3/8 / 1/2-inch port). The other end of the inflation hose is connected to line pressure, a pump or another source of pressure.
• Connect a second hose to the fitting if another one is available. The other end of the second hose should be connected to a gauge that has been calibrated.
• Before inflating the plug, use the appropriate method to block / brace it.
• Apply pressure to the plug using the inflation hose. Fill the plug to the inflation pressure specified on the plug.
• Allow the plug to settle for a few moments. If necessary, add pressure to maintain the rated inflation pressure.
• Continue testing the pipe / application. Once done, release back pressure behind the plug outside the danger zone.
• After releasing back pressure, relieve plug pressure from outside the danger zone until the plug is completely deflated.
• Take down the blocking / bracing system. Finally, take the plug out of the pipe.

What is the maximum temperature that these plugs can handle?
