FIG. 7001
Standard Coupling
1Check & lubricate gasket—
Check gasket to be sure it is compatible for
the intended service. Apply a thin coating of
Gruvlok lubricant to outside and sealing lips of
the gasket. Be careful that foreign particles do
not adhere to lubricated surfaces.
2Gasket Installation— Slip the
gasket over the pipe end making sure the
gasket lip does not overhang the pipe end.
On couplings 10" and larger it may be
easier to turn the gasket
inside out then lubricate
and slide the gasket over
the pipe end as shown.
3Alignment— After aligning the two
pipe ends, pull the gasket into position
centering it between the grooves on each pipe.
Gasket should not extend into the groove on
either pipe.
On couplings 10" and
larger, fip or roll the
gasket into centered
position.
4Housings— Place the coupling
housing halves over the gasket making sure
the housing keys engage the grooves. Insert
bolts and turn nuts fnger tight.
5Tighten Nuts— Tighten the nuts
alternately and equally to the specifed bolt
torque. The housing bolt pads must make metal-
to-metal contact.
Uneven tightening may cause the gasket to pinch.
6Assembly is complete—
Visually inspect the pipe joint to assure
the coupling keys are fully engaged in the pipe
grooves and the bolt pads are in frm even metal-
to-metal contact on both sides of the coupling.
NOTE: The housings for sizes 16” and larger are cast in four or more segments.
TO INSTALL: Loosely pre-assemble the segments into two “Housing Halves” making sure
that the alignment tang(s) and slot(s) on the bolt pad(s) are properly mated. Install the
“Housing Halves” as shown in steps 4 & 5. The coupling is properly installed when all bolt
pads are frmly together - Metal-to-Metal.
CAUTION: Proper torquing of coupling bolts is required to obtain specifed performance.
Over torquing the bolts may result in damage to the bolt and/or casting which could
result in pipe joint separation. Under torquing the bolts may result in lower pressure
retention capabilities, lower bend load capabilities, joint leakage and pipe joint separation.
Pipe joint separation may result in signifcant property damage and serious injury.
CAUTION: Use of an impact wrench is not recommended because the torque output can
vary signifcantly due to many variables including air pressure supply, battery strength and
operational variations.
