Attachment 1. Salient Characteristics_R.pdf

This is a Department of Defense memorandum dated 13 July 2026 establishing salient characteristics for a required component to support F-22A aircraft operations. The document specifies requirements for a Quick Disconnect Coupling Half (NSN: 4730-00-600-1758) needed to complete and install an Oil Service Widget on all F-22A airframes. The coupling half is a male component with the following critical specifications: 3.0-inch overall length, 3A thread class at all ends with 0.875-inch thread size, UNF thread series, 37.0-degree seat angle, 0.625-inch outside diameter tube accommodation, spring push-lock quick disconnect method with flared connection style at all ends, 0.750-inch leg length, internal quick disconnect connection type with threaded external tube first fluid end connection, safety locking and self-sealing features, and aluminum alloy or stainless-steel body with anodized surface treatment.

The coupling half serves as a critical component for a portable oil container/dispenser system that enables F-22A aircraft operators to service aircraft oil in austere locations without maintenance support infrastructure. This capability ensures aircraft remain mission-ready in divert landing scenarios and supports the U.S. Air Force's ability to project air power. The memorandum functions as a technical requirements document establishing the specifications that contractors must meet when providing this component for procurement under contract 673 CONS.
