Cherne pillow test balls block sewer flow easily – lightweight, flexible and supplied with a 0.8 m inflation hose with pressure gauge.

Cherne pillow test balls are pneumatic pipe plugs that block sewer flow in gravity pipelines, for example during leak testing, repair and maintenance. The flat design in heavy-duty elastic urethane makes the plug easy to handle and to get down through small-diameter openings, and it is petroleum resistant. The test ball is supplied with a 0.8 m inflation hose with pressure gauge and is inflated to the specified pressure, which is monitored using a calibrated gauge. The working temperature range is -18 to +52 °C. Custom sizes are manufactured on request.
