Standard Equipment

Refer to the RIDGID catalog for details on equipment
supplied with specific catalog numbers.
This pipe patching system is designed to re-
NOTICE
pair pipes. If properly used, it should not further damage
pipe that is being repaired. Pipe patching may not work
in all instances. Improper use of the pipe patching system
may obstruct the pipe. It may be necessary to access the
damage by digging or other methods to properly fix the
pipe damage.
Glossary of Common Pipe
Patching Terms
Containment
Liner ...................The restrictive liner used to prevent the
packer from over inflating in sections of
pipe with bends.
Containment
Tube ...................The restrictive tube used to prevent the
packer from over inflating in straight sec-
tions of pipe.
Encroachment
Zone ...................The area at each end of the packer that
will not expand to the full to the pipe di-
ameter when inflated. The patch CAN-
NOT be in this zone. If the patch is in this
zone, the patch will not be proper and
may block the pipe. The encroachment
zone is measured from the point where
the black rubber meets the metal end of
the packer. This zone is 3" long for the 2"
& 3" packers and 5" long for the 3"-4" &
4"-6" packers.
Final Hardness Time (Also Known As
"Cure Time") .......The time at which the patch has reached
its full hardness and is as strong as it will
get.
Flexible
Adapter ...............The short flexible air fitting assembly
located at the back end of the packer
which the Air Push Rod or the Patching
Air Hose connect to.
6
Internal Pipe
Temperature .......The temperature inside the pipe to be
patched, at the area to be patched. High-
er temperatures decrease resin set time,
lower temperatures increase set time.
Packer ................The inflatable bladder used to inflate and
hold the patch in place against the inside
of the pipe while the patch hardens and
cures.
Packer Sleeve ....The clear protective sleeve used to cover
the packer and prevent contact with the
resin.
Packer Test Insertion (Also Known As A
"Dry Run") ..........The process of ensuring that the packer
is able to navigate the pipe to the point
of repair. During the test insertion, the
packer should have a packer sleeve in-
stalled on it to protect the packer and
packer sleeve is lubricated with oil soap
to simulate the resin.
Patching Air
Hose ...................Used in place of the push rods and at-
tached to the air fitting on the packer
when pulling the packer into place.
Resin Set
Time ...................The time required for the resin to suffi-
ciently harden to allow the packer to be
deflated and removed. Resin set time is
temperature dependent. At this time, the
pipe can be put back into service.

Pre-Operation Inspection

WARNING
Before each use, inspect your pipe patching sys-
tem and correct any problems to reduce the risk of
serious injury from chemical burns, infections and
other causes and prevent system damage.
Always wear safety glasses, and other appropriate
protective equipment.
1. Clean the equipment to be used to aid inspection and
improve control during use.
2. Inspect the pipe patch equipment for the following
items:
• Proper assembly and completeness.
