CM TECH’s Jacket Patch Kit is made up of thermal insulation, heat reflective tape to hold the insulation in place, and a black self-sealing patch tape for weatherproofing the bundle. It is to be used to insulate an area where two bundles have been spliced together and the tubes connected with a tube fitting.
- To install the jacket patch kit at a splice.
Cut the ends of both bundles off square, exposing only the needed length of tubing.
Splice the tubes together using a standard compression type fitting. Wrap the area with the insulation until the diameter is built up to equal the diameter of the jacket on the bundle. Use the heat reflective tape to hold the insulation in place.
Use the Self-sealing patch tape to hold it inplace and prevent separation of the seams until it cures.
A : Remove and cut the insulation and outer jacket.
B : Place the insulation patch or tape.
C : Wrapping the heat reflective tape.
D : Wrapping the self-sealing patch tape.
- Install the jacket patch kit at the bundle end.
Cut the end of the bundle off square, exposing only the needed length of tubing.
Wrap insulation around the tubes and fittings. At the end where the patch material will end, wrap insulation around the individual tubes to build the diameter to equal the bundle. Use the heat reflective tape to hold the insulation in place.
Cut the patch material to extend over the bundle jacket 1”(25mm) and past the insulation on the individual tubes 3/8”(10mm)
Remove the protective wax paper backing and wrap it around the patch area. Overlap the ends by at least 1/2”(12mm) and press it into place. Use the fiberglass tape to hold it in place and prevent separation of the seams.
Fill the end with RTV sealant, such as CMT-9060, making sure that all exposed insulation is protected.
