Pillow Plugs
Cherne's Pillow-Style Test-Ball® and Muni-Ball® plugs are great for
blocking sewer flow and can also be used for sewer air testing. Made
from heavy-duty elastic urethane, these plugs are lightweight, flexible,
chemical and petroleum-resistant, and will fit through small-diameter
openings. Pillow-style plugs can be tethered with the attached tether
bars, and will work in all types of pipe, including ductile iron sizes.
Features:
• Equipped with a special 30' inflation hose,
read-back line and gauge
• A repair kit is available to fix small tears and punctures
• Muni-Ball® style plugs feature a bypass with threaded nipples on both
ends
