 3)  To install BACS13AP flareless sleeves, refer to "Preset the BACS13AP Flareless Sleeves".
 4)  If you use H-couplings (BACC42W) for repair, refer to "Install the BACC42W H-coupling".
 5)  If you use Cryofit unions (3P02111) for repair, refer to "Install the 3P02111 or 3PHS111 Cryofit Coupling.
 6)  If you use Permaswage unions (D10283) for repair, refer to "Install the Permaswage Fittings".
 7)  To install Cryolive flareless sleeve assembly, refer to "Install the Cryolive Flareless Sleeve Assemblies".
 NOTE: Use only the complete Cryolive flareless sleeve
____ assembly, consisting of a Cryolive sleeve, coupling nut and plastic cap. The Cryolive flareless sleeve assembly, in Sizes 10, 12 and 16, requires use of a longer length coupling nut. The longer length coupling nuts are not interchangeable with standard BACN10- and MS21921 coupling nuts.
 8)  If you use Rynglok tube to tube unions for repair, refer to "Rynglok Union installation".
Install the repair section and tighten the nuts
 (AMM 20-11-00/201).
When you use a Cryofit Union or H-Coupling in the repair
 section, install it after you tighten the flareless fittings in
 their positions.
When you use a Permaswage union in the repair section, you must
 make allowance for swage growth. Tighten the repair section in
 position after installation of the Permaswage union.
When you replace a tube bend section, make sure you keep the
 minimum straight length specifications for all fittings
 (Fig. 812).
When you use a CRYOLIVE flareless sleeve/coupling nut in
 conjunction with a permanent Cryofit, H-Coupling or Permaswage
 union, tighten the flareless coupling nut hand tight before
 installing the permanent fitting to minimize axial preload on
 the CRYOLIVE sleeve.
