The purpose of this specification sheet is to set up a standardized part numbering system for O-rings procured to MIL-P-83461 for use in straight thread tube boss fittings.
AMSP83461/2 is a word for word copy of MIL-P-83461/2. AS83461/2 - "Packing, Preformed - M83461 Straight Thread Tube Fitting Boss" was released on 25 September 2009 to replace AMSP83461/2. On 20 January 2010, the U.S. Department of Defense withdrew its adoption of AMSP83461/2 and directed that future acquisition refer to AS83461/2. To streamline the acquisition process and to be consistent with the actions of the U.S. Department of Defense AMSP83461/2 is cancelled and replaced by AS83461/2 for procurement purposes.
