APPLICATION OF ADHESIVES.
a.
General. Adhesives are recommended in some tasks to ensure and strengthen seals. The follow-
ing information describes their correct use and application.
b.
Silicone Sealant. Silicone sealant (Item 16, Appendix F) is used to seal parts against moisture.
Use the following instructions when applying:
(1)
Anytime a seal is broken, the part must be thoroughly cleaned to remove any remaining
sealing compound and dirt.
(2)
Thoroughly clean surface before applying sealant.
(3)
When applying sealant, ensure that the area is completely covered. Press sealant into and
around parts as necessary.
(4)
Silicone sealant will set in 15-30 minutes depending on temperature and humidity.
c.
Loctite Adhesive. Loctite adhesive (Item 1, Appendix F) provides a seal against leakage and a
resistance to loosening when used in the assembly of threaded, slip-fitted, or press-fitted parts. Always use grade
of Loctite adhesive specified and never use when other retaining means are provided. such as lockwires, lock-
washers, lockplates, and fasteners. DO NOT use Loctite adhesive on brass fittings plugs or items that need fre-
quent servicing, or when operating temperature exceeds 300°F (149°C). Apply Loctite adhesive as follows:
(1)
Before application, clean threads to remove oil, grease. and metal chips
(2)
Apply Loctite adhesive to second and third threads. DO NOT apply to first thread to ensure
system cleanliness.
(3)
Loctite adhesive will dry in 6-24 hours at room temperature.
(4)
Adjustments for elbows, gages, and valves can be made up to 24 hours after application
without affecting the seal.
