The Gruvlok® CTS Copper System offers an installer of large diameter

copper tubing an alternative to the conventional soldering and brazing.

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

sweating or brazing as this system requires only a wrench for assembly on

grooved end pipe.

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.

Step 4 – Final Assembly.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.

READY FOR INSTALLATION - RIGHT OUT OF THE BOXDo 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 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.

Step 2 – Gasket Preparation. 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.

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.

Method #1Slide 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.

A. Slide the coupling on the copper tube past the groove. The bolts and nuts can be hand tightened to position the coupling in place.

B. Align the mating copper tube end. Align the two adjoining tubes together.

C. Slide the coupling back over the grooves so that the coupling keys are located over the respective grooves on both copper tube ends.

D. Follow the instructions on fastening the coupling as shown in Step 4.

*CAUTION: When using an impact wrench, verify that the output of the impact wrench is within the required torque range. It is recommended that a torque wrench be used for accurate assembly in order to obtain specified performance.

Step 5 – Final Inspection.Ensure the coupling is properly aligned in the grooves and the housing halves are in metal-to-metal contact, depicted in the pictures to the right.

Method #2Slide 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 fitting so that the groove and keys are aligned.

B. Bring the copper tube end or fitting towards the coupling and insert so that the groove and coupling keys are aligned.

C. Hand tighten the nuts to correctly position the couplings keys over the respective grooved ends.

D. Follow the instructions on fastening the coupling as shown in Step 4.

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.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 5 – Housing Assembly.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.

Step 6 – Final Assembly.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.

Step 7 – Final Inspection.Ensure the coupling is properly aligned in the grooves and the housing halves are in metal-to-metal contact, depicted in the pictures to the right.

REINSTALLATION OF THE FIGURE 6402 CTS SLIDELOK™ COUPLINGThe 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.

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.

The 6400 Rigid Coupling is a snap.Installation & AssemblyThe 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 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.
