The introduction of the SlideLOK CTS has increased the installation speed of
the groove copper system while made it easier to install compared to
conventional methods. With grooved copper, temperature and weather
conditions are no longer a factor when planning installations. There is no

The copper system is “flame-free”. Essentially you save time and enjoy a very
reliable system that is both versatile and economical. Safety is a factor as
there is no fire hazard, especially in a retrofit installation. The ease of
assembly is a great benefit in new construction and ease of disassembly is
ideal for renovation, retrofit or expansion.

Gruvlok® CTS Copper System
Figure 6402 CTS SlideLOK® Ready for Installation Coupling
The CTS SlideLOK coupling is a ready for installation coupling
designed to reduce installation time. The slide action allows
for greater flexibility during installation. The patented gasket
provides four separate sealing surfaces for added protection. The
engineered metal-to-metal installation requirement is a quick and
easy indication of proper assembly.
The CTS SlideLOK is designed to be used with copper tube sizes
2" - 4" and produces a secure, rigid joint connection.
The CTS SlideLOK coupling allows for a maximum working
pressure of 300 psi for type K, L or M. Contact an Anvil
representative for other copper tube pressure ratings.

INSTALLATION
READY FOR INSTALLATION - RIGHT OUT OF THE BOX
Do not disassemble the CTS SlideLOK™ Coupling. The Figure 6402 coupling is ready for installation. The bolt and gasket do not need to be removed.
Step 3 – Assembly.
The CTS SlideLOK Figure 6402 may be
installed by one of two methods. The
preferred method depends on the type of
components being joined and their
orientation. Please review both methods
before installing.
Step 2 – Gasket Preparation.
Step 1 – Copper Tube
Preparation.
Copper tube ends are to be roll grooved
copper tube according to Anvil specifications.
The tube end must be smooth and free
from metal burrs or projections.
Ensure the gasket is suitable for the
intended application by referring to the
Anvil gasket compatibility chart. Apply a
light coating of Gruvlok® Xtreme™
Lubricant to exposed gasket surfaces.
Method #1
Method #2
Slide the CTS SlideLOK coupling completely over the grooved
copper tube end. This will allow a clear and un-obstructed view
of the tube for correct alignment.
Slide the CTS SlideLOK™ coupling half way onto the copper
tube end or fitting. This will better accommodate fitting, and
valve accessories during installation.
A. Slide the coupling on the
copper tube past the groove.

Step 5 – Final
Inspection.
The CTS SlideLOK
coupling is designed to
achieve pad to pad
(metal-to-metal contact)
using either an impact
wrench* or wrench. The
intended torque range for
the coupling is located in
Table 1. Securely tighten nuts alternately and equally until the
housing halves are in metal-to-metal contact.
Ensure the coupling is
properly aligned in the
grooves and the housing
halves are in metal-tometal contact, depicted in

Reinstallation of the Figure 6402 CTS SlideLOK™ Coupling
The CTS SlideLOK coupling is designed to be installed in the ready for installation assembly position once. After the initial assemble the following
steps are to be taken to re-install the Fig. 6402 CTS SlideLOK coupling.
Step 1 – De-pressurize
the System.
De-pressurize the system
before removing the CTS
SlideLOK Coupling.
Disassemble the couplings by
removing the nuts, bolts and
gasket from the housing
halves. A wrench is required to
overcome the epoxy used to
secure the nuts on the bolts.
Step 2 – Copper
Tube Preparation.
Copper tube ends are to be roll
grooved copper tube according to
Anvil specifications. The tube
end must be smooth and free
from metal burrs or projections.
Step 3 – Gasket
Preparation.
Ensure the gasket is suitable
for the intended application
by referring to the Anvil gasket
compatibility chart. A light
coating of Gruvlok® XTreme™
lubricant must be applied to
the gasket prior to installation.
Step 4 – Copper
Tube Alignment and
Gasket Installation.
Place each housing halves on
the copper tube making sure
the housing key fits into the
groove. Be sure that the
tongue and recess portions of
the housing mate properly.
Insert the bolts.
Slide the gasket onto the
copper tube then align the two
tube ends together. Pull the
gasket into position, centering
it between the grooves on each
copper tube. Gasket should
not extend into the groove on
either copper tube.
Step 6 – Final
Assembly.
Step 7 – Final
Inspection.
The CTS SlideLOK
coupling is designed to
achieve pad to pad
(metal-to-metal contact)
using either an impact
wrench* or wrench. The

Gruvlok® CTS Copper System
The 6400 Rigid
Coupling is a snap.
STEP 1 –
Check and lubricate gasket
STEP 2 –
Gasket Installation
STEP 4 –
Assemble Housings
Installation & Assembly
The Fig. 6400 Coupling from Gruvlok is
specially designed to provide a rigid pipe
connection to meet the specific demands
of copper tubing installation. Fast and
easy swing-over installation of the rugged
lightweight housing produces a secure, rigid
pipe joint. Available with the EPDM flush
gap style gasket as the standard gasket.
Step1 – Lube Gasket.
Check the gasket to be sure it is compatible
for the intended service. Apply a thin coating
of Gruvlok® Xtreme Lubricant to the entire
surface, both internal and external, of the
gasket. Be careful that foreign particles do
not adhere to the lubricated surfaces.
STEP 3 –
Alignment
Step 2 – Install Gasket.
Slip the gasket over one tube, making sure
the gasket lip does not overhang the tube end.
Step 3 – Alignment.
After aligning the two tube ends together,
pull the gasket into position, centering it
between the grooves on each tube. The
gasket should not extend into the groove on
either tube or between the tube ends.
Step 4 – Assemble Housings.
Remove one nut and bolt and loosen the
other nut. Place one housing over the gasket,
making sure the housing keys fit into the
tube grooves. Swing the other housing over
the gasket and into the grooves on both
tubes, making sure the tongue and recess of
each housing is properly mated. Re-insert
the bolt and run-up both nuts finger tight.
Step 5 – Tighten Nuts.
Securely tighten nuts alternately and equally
to the specified bolt torque, keeping the gaps
at the bolt pads evenly spaced. Assembly is
complete. Visually inspect the pipe joint to
assure the coupling keys are fully engaged in
the pipe grooves. The bolt pads are to have
equal gaps on each side of the coupling.
NOTE: Copper is a soft material, and in
some cases, the bolt pads may come close to
metal-to-metal contact.

anvil INTERNATIONAL
CAUTION: Uneven tightening may cause
the gasket to pinch. The gasket should not
be visible between segments after the bolts
are tightened. Proper torquing of coupling
bolts is required to obtain specified
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.
