18. Pneumatic Test Balls

Cherne pneumatic Test Ball® and Muni-Ball pipe plugs have been the contractor’s choice since 1953. Used in residential DWV systems and sanitary/storm sewers, Cherne pneumatic pipe plugs do it all! Larger sizes are available with our patented Rupture Disc Technology, which prevents over-inflation. This eliminates plug damage due to over-inflation and enhances user safety.
