This SAE Aerospace Standard (AS) covers the requirements for threaded lubrication fittings@ straights and elbows@ to be used for admitting and retaining lubricants supplied by pressure lubricating equipment. Purpose: The purpose of this standard is to replace MIL-F-3541 with a document consistent with the performance requirements of the specification it supersedes. Classification: Lubrication fittings covered by this standard shall be of the following types as specified: Types: The types of lubrication fittings shall be as follows: a. Type I: See AS15001@ surface check@ 1/4-28 taper threads@ carbon steel b. Type II: See AS15002@ surface check@ straight threads@ carbon steel c. Type III: See AS15003@ surface check@ 1/8 pipe threads@ carbon steel d. Type IV: See AS15004@ surface check@ 1/4-28 taper threads@ Ni-Cu alloy e. Type V: See AS15005@ throat or surface check@ 1/8 pipe threads@ Ni-Cu alloy f. Type VI: See AS15006@ leak proof@ 1/8 pipe threads@ carbon steel g. Type VII: See AS15720@ throat or surface check@ 1/4-28 taper threads@ corrosion resistant steel h. Type VIII: See AS15721@ throat or surface check@ 1/8 pipe threads@ corrosion resistant steel
