TM 10-3930-659-34 2-12. LUBRICATION INSTRUCTIONS. Refer to LO 10-3930-659-12 for detailed, illustrated instructions on proper lubrication. Some general practices to remember: (1) Use the correct lubricant. (2) Keep lubricants clean. (3) Clean all fittings prior to lubrication. (4) Lubricate clean disassembled and new parts to prevent rust (see paragraph 2-7). 2-13. APPLICATION OF ADHESIVES. a. General. Adhesives are recommended in some tasks to ensure and strengthen seals. The following information describes their correct use and application. b.  Silicone  Sealing  Compound.  Silicone  sealing  compound  (Item  17,  Appendix  B)  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 silicone sealing compound. (3) When  applying  silicone  sealing  compound,  ensure  that  the  area  is  completely  covered.  Press  silicone sealing compound into and around parts as necessary. (4) Silicone sealing compound will set in 15-30 minutes depending on temperature and humidity. c.  Loctite  Adhesive.  Loctite  adhesive  (Item  2,  Appendix  B)  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  the  grade  of  Loctite adhesive specified and never use when other retaining means are provided, such as lockwires, lockwashers, lockplates, and  fasteners.  DO  NOT  use  Loctite  adhesive  on  brass  fittings,  plugs,  or  items  that  need  frequent  servicing,  or  when operating temperatures exceed 300°F (149 OC). 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. 2-7
