3. Hand Assembly of the Graplon Connector on to the Coiled Tubing
1. Prepare the end of the coiled tubing using the standard wheel pipe cutter
and remove the burr left on the O.D. of the tube using a file.

2. Screw the Grapple Collet into the Grapple Housing until the end face of
the Collett sits flush with the end of the Grapple Housing.

5. 3. Slide the Grapple assembly approximately 6 inches up the coiled tubing
and lock it in place with the single grub screw (use a 3/16” A/F Allen Key).

6. 4. Install the external and internal O-rings and the internal metal seal ring
against the bottom shoulder in the Seal Housing. (The internal O–ring is
situated to aid installation (seen in next slide) and is not required to seal).

7. 5. Fit the Seal Housing onto the coiled tubing. Use a soft mallet tap and
lightly rotate the Seal Housing for this operation. Ensure that the metal seal
ring and Seal Housing sit tight against the end face of the coiled tubing.
(seen held in position by internal O-ring below right).

8. 6. Release the single grub screw in the Grapple Housing and carefully
lower the assembly onto the Seal Housing to rest against the white face.
Check that the Seal Housing and the metal seal ring are still correctly
positioned against the end face of the coiled tubing.

10. 8. Screw the Bottom Sub on to the Grapple Housing until it reaches the pin
thread undercut (arrowed below) and tighten by hand - then release the single
grub screw in Grapple housing (inset below) and continue to hand tighten on
to the coiled tubing. Using the Spanner provided tighten the bottom sub a
further 1/2 to1 turn so that the grapple is secured to the coiled tubing and able
to carry the weight of the Hydraulic Jig Assembly.

11. Hydraulic Installation Main Components

12. Installing the Graplon Connector with Hydraulic Jig Assembly
1. Using the correct size jig and installation dolly fit the Hydraulic Jig
Assembly over the coiled tubing to rest on Graplon connector as shown

13. 2. Attach the hydraulic hand pump and apply hydraulic pressure (6000 PSI).

3. With the connector under hydraulic load the Bottom Sub can now be
screwed tight, using the spanner provided tighten the bottom sub until
solid resistance is felt and then continue a further ¼ to ½ a turn (this
equates to 300 Ft/Lbs torque approximate). NOTE: The pin undercut
(arrowed below) will still be visible.

15. 4. Lock the four grub screws in the Bottom Sub (use a 1/8” A/F Allen Key).

16. 5. Release the hydraulic pressure and with the hydraulic piston and dolly
fully retracted clear of the Graplon connector (arrowed below left) remove
the Hydraulic Jig Assembly.

17. 6. Tighten the Grapple housing single grub screw (inset below) and the
installation is now complete and ready to run BHA.
The Graplon connector can easily be removed by reversing the installation
process – no need to cut the coiled tubing.
