Cherne 041386 is an 8" TEST-BALL® plug. It is an effective solution for blocking the flow. The item can also be used as a back plug for sewer air tests.
The plug is made of natural rubber that offers great expansion and memory. If the inflation valve in a large plug is damaged, it can be easily replaced as it is removable.
The patented Rupture Disc Technology is intended to prevent over-inflation of the pneumatic plug. In addition, it protects the plug from damage.
Please read the manufacturer’s instruction manual before using the plug. Select the product according to your application.
