General
Description
The GRINNELL G-FIRE Figure 579
Grooved Rigid Couplings provide a
rigid joint by firmly gripping along the
full circumference of the pipe grooves.
Figure 579 couplings are a dependable
method of joining pipe and are an eco-
nomical alternative to welding, thread-
ing, or using flanges.
Figure 579 couplings are rated at pres-
sures up to 365 psi (25,2 bar) depend-
ing on pipe size and wall thickness
when used in fire protection service
applications. Refer to Table A.
NOTICE
The GRINNELL G-FIRE Figure 579
Grooved Rigid Coupling described
herein must be installed and main-
tained in compliance with this docu-
ment, as well as with the applicable
standards of the Approval agency, in
addition to the standards of any other
authorities having jurisdiction. Failure
to do so may result in serious personal
injury or impair the performance of
these devices.
Never remove any piping component
nor correct or modify any piping defi-
ciencies without first de-pressurizing
and draining the system. Failure to do
so may result in serious personal injury,
property damage, and/or impaired
device performance.
It is the designer’s responsibility
to select products suitable for the
intended service and to ensure that
pressure ratings and performance
data are not exceeded. Material and
gasket selection should be verified to
be compatible for the specific applica-
tion. Always read and understand the
installation instructions.
The owner is responsible for main-
taining their mechanical system and
devices in proper operating condi-
tion. Contact the installing contrac-
tor or device manufacturer with any
questions.

Installation
GRINNELL G-FIRE Figure 579 Grooved
Rigid Coupling must be installed in
accordance with this section.
General Instructions
Always read and understand the
instructions. Never remove any piping
component without verifying that the
system is depressurized and drained.
The Figure 579 Grooved Rigid Cou-
pling with additional lubrication is rec-
ommended for applications below
40°F (4°C).
The installation is based on pipe
grooved in accordance with Standard
Cut Groove or Roll Groove Specifica-
tions. Refer to Technical Data Sheet
TFP1898 for additional information.
Step 1. Inspect exterior groove and
ends of the pipe to verify all burrs,
loose debris, dirt, chips, paint and any
other foreign material such as grease
are removed. Pipe end sealing sur-
faces must be free from sharp edges,
projections, indentations, and/or other
defects.
Grade “A” gaskets are supplied with a
pre-lubricant and do not require addi-
tional lubrication for applications above
40°F (4°C).
NOTE: Additional lubrication must be
used in dry pipe and freezer applica-
tions. A silicone based lubricant is
recommended.
To prevent deterioration of the gasket
material a petroleum lubricant should
not be used on Grade “A” “EPDM”.
CAUTION
Removal of the nut from the bolt may
result in the coupling segments sepa-
rating at the hinges and the coupling
disengaging from the pipe. Use caution
to avoid equipment damage and/or
personal injury.
Step 2. Do not remove the nut from the
bolt. Open the coupling by extending
the coupling segments out to the extent
allowed by the bolt and nut.
Step 3. Push the gasket/coupling onto
one end of the pipe until the center-
stop of the gasket is in contact with the
end of the pipe (Ref. Figure 2).
NOTE: The gasket center-stop should
not ride up onto the gasket sealing
surface (Ref. Figure 2).
CAUTION
Do not leave coupling unattended on
a single pipe end as it may disengage
from the pipe. Failure to do so may
result in equipment damage and/or
personal injury.
Step 4. Slide the other pipe end into
the gasket/coupling ensuring that it
makes contact with the center stop of
the gasket (Ref. Figure 2). Both pipes
should be aligned vertically and hori-
zontally. Verify that the housing is over
the gasket and that the housing keys
are aligned with the pipe grooves.
Step 5. Tighten nut to the recom-
mended bolt torque (Ref. Table B).
Visually inspect the coupling to ensure
that the housing keys are engaged into
the pipe grooves.
NOTICE
The 2 in. to 8 in. (DN50 to DN200) cou-
plings have an intended gap of up to
1/16 in. (1,60 mm) at the bolt pad to
allow for positive rigid gripping onto
the pipe.
Bolt-torque information is supplied
as a guideline and may be used when
setting the torque on power impact
wrenches. Refer to the manufacturer’s
instructions for settings.
Bolt lengthens require the use of deep
or extra-deep-well sockets. Sockets
inner depth information is supplied for
reference only. (Ref. Figure 4) For spe-
cific socket recommendations, contact
Technical Services.

Before closing a fire protection system
main control valve for maintenance
work on the fire protection system
that it controls, obtain permission to
shut down the affected fire protection
system from the proper authorities
and notify all personnel who may be
affected by this decision.
After placing a fire protection system
in service, notify the proper authorities
and advise those responsible for moni-
toring proprietary and/or central station
alarms.
The owner is responsible for the inspec-
tion, testing, and maintenance of their
fire protection system and devices in
compliance with this document, as well
as with the applicable standards of the
NATIONAL FIRE PROTECTION ASSO-
CIATION, such as NFPA 25, in addition
to the standards of any authority having
jurisdiction. Contact the installing con-
tractor or product manufacturer with
any questions. Any impairments must
be immediately corrected.
Automatic sprinkler systems are rec-
ommended to be inspected, tested,
and maintained by a qualified Inspec-
tion Service in accordance with local
requirements and/or national codes.
