Fitting Installation Using Loctite 567 or Loctite 565 Thread Sealant
1.
Disengage fitting parts.
2.
Remove protective plug from the BATT flange and protective cap from the fitting threaded part.
3.
Clean thread surfaces (external and internal) with a cleaning solvent (e.g. Loctite) and allow to
dry.
4.
Spray thread surfaces (external and internal) with Loctite 7649 primer and allow to dry;
5.
Apply a 360 degree bead of thread sealant to the leading threads of fitting part, leaving the first
thread free.
6.
Force the sealant into the threads to thoroughly fill the voids.
7.
Install fitting threaded part into the BATT flange. As a general rule for 1", 1.5" and 2" threads,
hand tighten the fitting part and then tighten three more full turns with a wrench. For 3" threads,
hand tighten the fitting part and then tighten two more full turns with a wrench.
8.
Allow the sealant to cure a minimum of 24 hrs.
9.
Engage BATT fitting.
Fitting Installation Using Loctite 55 Thread Sealant
1.
Disengage fitting parts.
2.
Remove protective plug from the BATT flange and protective cap from the fitting threaded part.
3.
Clean thread surfaces (external and internal) with a wire brush prior to application of the sealant.
4.
Hold the end of the pipe sealing cord against the male nipple with one finger, approximately two
threads away from the end.
5.
Wind the fiber onto the pipe threads away from the end of the pipe. The grooves of the threads
should be filled without completely masking the pitches or the thread (it is not necessary to follow
the valley of the thread).
Important Note
Threaded connections can be disassembled with standard hand tools. Cured sealant can be re-
moved with a combination of soaking in a Loctite solvent (or equivalent) and mechanical abrasion
such as with a wire brush.
