To identify the damaged tube, insert a soft wire or pipe cleaner into the point of tube damage and work it toward the honeycomb face. The wire protruding through the honeycomb face identifies the affected tube within the bundle. Once the damaged tube has been located, repairs may be made. Warning! Do not attempt to clear undamaged tubes by inserting a welding rod, wire, or other devices. 2). Ensure that the honeycomb face is clean and dry in the area to be repaired. 3). Use a cotton swab or pipe cleaner, and clean the inside of the tube with alcohol or other appropriate solvents. 4). Insert a piece of fluoropolymer plugging material of the proper diameter about 1/2 inch (13 mm) long into the leaking tube end, allowing approximately 1/16 inch (1.6 mm) protrusion from the honeycomb face. If the plugging material is too thick to enter the honeycomb, stretch the plugging material slightly to reduce its diameter.
