WARNING: MAKE SURE YOU MAKE NO PUMP ADJUSTMENT THAT CAN CAUSE THE SWAGE
_______ TOOL HYDRAULIC PRESSURE TO BE MORE THAN THE MANUFACTURERS RECOMMENDATIONS. THE DEUTSCH RECOMMENDATION FOR D12000 SERIES TOOLS IS 5760 PSI MAXIMUM AND FOR THE DLT SERIES IS 10000 PSI MAXIMUM. IF PRESSURE IS GREATER THAN THE ABOVE VALUES INJURY AND DAMAGE CAN OCCUR.
(7)
Swage the union to the tube as shown in the manufacturer's recommended procedures.
(8)
Swage each end three times.
S 358-379
NOTE: After the initial swage, move the swage head between 30 and
____ 45 degrees from the previous swage position before you swage again.

Make resistance measurements for all Permaswage repair installations in wing tanks and fuel vapor areas (AMM 20-11-05/401).
S 798-385
(14)
For Permaswage fitting repairs in general areas, do a leak test as follows:
(a)
Pressurize the system for a minimum of 5 minutes.
(b)
Rub the tube and fittings with a clean white cloth to find leakage.
S 218-386
(15) Examine the tube-to-fitting interface for hydraulic leaks you can see.
NOTE: When dimensional or leakage specifications are not met,
____ you can swage again. Then do a leak test. You must replace fittings you cannot seal.

The Rynglok in-line tube unions (Fig. 834), sizes 04, 06, 08, 10, 12, and 16 are used with 304 1/8 hard CRES to repair Ti-3AL-2.5 and 21-6-9 CRES. The same unions plus a size 20 are used with 6061-T6 aluminum tube to repair 6061-T6 aluminum tu be, provided the bare areas of the tubing are painted after swaging to limit the possibility of galvanic corrosion ocurring.
(3)
When you do a repair, remove the part of the tube with the damage. If the area of the tube damage is less than the value listed in (F ig. 805), use one Rynglok union for repair.
(4)
If the tube damage is longer than the value listed in (Fig. 805), put in a tube splice and install the splice with two fittings. The splice must be equal to or slightly shorter than the removed tube section. The minimum length of tubing to be removed is shown in (Fig. 836). Fittings and tubing material sizes are shown in (Fig. 835).
