About the product
Muniboll pipe stoppers are pneumatic pipe stoppers with a through-port that lets you bypass pump during repairs and other interventions while flow in the pipe continues. They are also used for leak testing of gravity sewers and can block most pipe types. The stopper is made from natural rubber and is Kevlar-reinforced in the larger sizes. The through-port is threaded, female or male depending on size, and the stoppers are supplied with a Schrader valve for air inflation. Working temperature -18 to +52 °C, and inflation is done with air, water or inert gas.
Benefits
- Through-port allows bypass pumping with continued flow in the pipe
- Natural rubber with good sealing properties and excellent expansion
- Kevlar-reinforced in larger sizes for extra durability
- Schrader valve for air inflation as standard
- Pull ring reduces the risk of the stopper being drawn into the pipe
- Long service life when stored away from sunlight
