Purpose
This specification defines the requirements for lubrication of 37-degree flared tube fittings as specified in KSC-GP-425 and applicable SAE Aerospace Standards to prevent galling and to provide consistent preload and seal compression.
Applicability
a) This specification may be used for the following fluids:
i. all hydrocarbons (e.g., Rocket Propellant-1, hydraulic fluid).
ii. all gaseous and liquid inert fluids (e.g., argon, helium, nitrogen).
iii. gaseous and liquid air, carbon dioxide, hydrogen, and oxygen.
iv. hypergolic fuels and oxidizers (e.g., hydrazine, monomethylhydrazine,
v. refrigerants (e.g., ammonia, R-124, R-134a)
vi. water.
b) These requirements apply to new equipment that has not been verified to meet requirements of a previous revision of this standard. Equipment designed or fabricated prior to the effective date of this standard may be verified as acceptable for use against the requirements of a previous revision of this standard. Any design changes to such equipment shall meet the requirements of this revision of this standard.
intended Use:
Lubrication in accordance with this specification is intended to minimize galling of mating surfaces. Strict adherence to this specification is required to prevent fluid system contamination.
