COUPLING INSTALLATION
CAUTION
• A thin coat of Victaulic Lubricant shall
be used on the gasket sealing lips and
exterior to prevent the gasket from
pinching/tearing during installation.
Failure to use a compatible lubricant will
cause gasket damage, resulting in joint
leakage and property damage.
1. CHECK GASKET AND LUBRICATE: Check
the gasket to verify that it is suitable for the
intended service. The color code identifies the
material grade. Refer to Victaulic publication
05.01 for the color code chart, which can be
downloaded at victaulic.com. Apply a thin coat
of Victaulic Lubricant or silicone lubricant to the
gasket sealing lips and exterior.
2. POSITION GASKET: Position the gasket
over one pipe end until the gasket’s center leg
contacts the pipe end.
3. JOIN PIPE ENDS: Align and bring the other
pipe end into position until contact with the
gasket’s center leg occurs.
4. LUBRICATE BOLT THREADS: Lubricate
the bolt threads with a thin coat of Victaulic
Lubricant or silicone lubricant.
WARNING
• Verify that the gasket does not become
rolled or pinched while installing the
housings.
• Verify that the housings’ tongue and
recess features are mated properly
(tongue in recess), as shown below.
Failure to follow these instructions will
cause joint failure, resulting in death
or serious personal injury and property
damage.

5a. INSTALL HOUSINGS: Install the housings
over the gasket and rings with the tongue and
recess features mated properly (tongue in
recess). Verify that the housings’ ribs engage
the rings completely on both pipe ends without
interference from the applied welds. Grind
welds, if necessary, in accordance with the
specifications on page 2.
5b. INSTALL BOLTS/NUTS: Install the bolts.
Thread a nut finger-tight onto each bolt. Verify
that the oval neck of each bolt seats properly in
the bolt hole.

6. TIGHTEN NUTS: Tighten all nuts evenly by
alternating sides (follow the sequence shown
above) until the gaps are equal at the bolt pads.
Apply torque to each nut with a torque wrench.
Refer to the “Style 809N Required Assembly
Torques and Helpful Information” table on the
following page for the torque requirement.
NOTE: It is important to tighten all nuts evenly
to prevent gasket pinching.
