3.CHECK GASKET MATERIAL GRADE: Check the gasket material
grade 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.
CAUTION
• Read and understand all instructions before attempting to install
any Victaulic piping ­products.
• A compatible lubricant shall be used to prevent the gasket from
pinching/tearing during installation.
• Depressurize and drain the piping system before attempting
to install, remove, adjust, or maintain any Victaulic piping
­products.
Use of an incompatible lubricant will cause gasket degradation,
resulting in joint leakage and property damage.
• Wear safety glasses, hardhat, and foot protection.
Failure to follow these instructions could result in death or serious
­personal injury and property damage.
IMPORTANT INFORMATION
CORRECT - StrengThin100 Groove Profile
INCORRECT - Original Groove System (OGS) Groove Profile
The Style E497 Installation-Ready™ Rigid Coupling shall be used ONLY
with stainless steel pipe that is prepared to StrengThin™100 groove
specifications. DO NOT attempt to install Style E497 Couplings on pipe
prepared to any other groove specification. Refer to Victaulic publication

REV_C
1.DO NOT DISASSEMBLE THE
COUPLING: Style E497 Installation-Ready™
Rigid Couplings are designed so that the
installer does not need to remove the
bolts and nuts for installation. This design
facilitates installation by allowing the
installer to directly insert the grooved end of
pipe/mating components into the coupling.
2.CHECK PIPE/MATING COMPONENT
ENDS: The outside surface of the pipe/
mating component, between the groove
and pipe/mating component end, shall
be smooth and free from indentations,
projections, weld seams, and roll marks
to ensure a leak-tight seal. All oil, grease,
loose paint, dirt, and cutting particles
shall be removed. The pipe/mating
component outside diameter “OD” and
groove dimensions shall be within the
tolerances published in current Victaulic
specifications, which can be downloaded
at victaulic.com.
4.LUBRICATE GASKET SEALING LIPS: Apply a thin coat of Victaulic
Lubricant or silicone lubricant only to the sealing lips, as shown above.
NOTE: The gasket is supplied with a factory-applied lubricant, so
it is not necessary to remove the gasket from the housings to apply
additional lubricant to the exterior surface.
WARNING
• Never leave a Style E497 Coupling
disassembled or ­partially assembled. A
disassembled or partially assembled Style
E497 Coupling poses a drop h­azard or a
burst hazard during testing.
• Keep hands away from the pipe/mating
­component ends and the openings of the
coupling when attempting to insert the pipe/
mating component ends into the coupling.
Failure to follow these instructions could result
in serious personal injury and/or ­property
damage.

6.TIGHTEN NUTS: Tighten the nuts evenly by alternating sides until
metal-to-metal contact occurs at the bolt pads. Verify that the housings’
keys engage the groove completely in each pipe’s/mating component’s
grooved end during tightening.
NOTICE
• Nuts shall be tightened evenly by alternating sides to prevent
gasket pinching.
• An impact wrench or standard socket wrench with a deep-well
socket can be used to bring the bolt pads into metal-to-metal
contact.
• Refer to the “Style E497 Helpful Information” and “Impact
Wrench Usage Guidelines” sections.
I-E497_2
7.Visually inspect the bolt pads at each joint to ensure that metal-tometal contact is achieved across the entire bolt pad section.
WARNING
• Visual inspection of each joint is critical.
• Improperly assembled joints shall be corrected before the
system is placed in service.
Failure to follow these instructions could cause joint failure,
resulting in death or serious personal injury and property damage.

System / Installation Instructions
Perform trial assemblies with the impact wrench and check the
assemblies with socket or torque wrenches to help determine the
capability of the impact wrench. Using the same method, periodically
check additional nuts throughout the system installation.
For safe and proper use of impact wrenches, always refer to the impact
wrench manufacturer’s operating instructions. In addition, verify that
proper impact grade sockets are being used for coupling installation.
WARNING
Failure to follow instructions for tightening coupling hardware
could result in:
• Personal injury or death
• Bolt fractures
• Damaged or broken bolt pads or coupling fractures
• Joint leakage

WARNING
1.Verify that the system is depressurized and drained completely before
attempting to disassemble any couplings.
2.Check pipe/mating component ends and the gasket, as described on
page 1. Inspect the gasket for any damage or wear. If any damage or
wear is present, replace the gasket with a new Victaulic-supplied Style
E497 gasket of the appropriate grade.
CAUTION
• A compatible lubricant shall be used to prevent the gasket from
pinching/tearing during re-installation.
Use of an incompatible lubricant will cause gasket degradation,
resulting in joint leakage and property damage.
• Nuts shall be tightened completely until metal-to-metal c­ontact
occurs at the bolt pads.
• DO NOT continue to tighten the nuts after the visual installation
guidelines for the coupling, described in Step 6 on the previous
page, are achieved.
Failure to follow these instructions could cause gasket pinching and
coupling damage, resulting in joint failure, serious personal injury,
and property damage.
Due to the speed of assembly when using an impact wrench, the
installer should take extra care to verify that nuts are tightened until
proper assembly is complete. Always refer to the specific product
installation instructions for complete installation requirements.
Impact wrenches do not provide the installer with direct “wrench
feel” or torque to judge nut tightness. Since some impact wrenches
are capable of high output, it is important to develop a familiarity with
the impact wrench to avoid damaging or fracturing the bolts or the
coupling’s bolt pads during installation. DO NOT continue to tighten the
nuts after the visual installation guidelines for the coupling, described in
Step 6 on the previous page, are achieved.
If the battery is drained or if the impact wrench is under-powered, a
new impact wrench or a new battery pack shall be used to ensure the
visual installation guidelines for the coupling, described in Step 6 on the
previous page, are achieved.
