LARGE SINGLE SIZE TEST & MUNI PILLOW PIPE 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
