This is a DD Form 2169 Special Packaging Instruction document dated July 21, 2025, specifying preservation, protection, and packaging requirements for a hydraulic linear cylinder (Part Number 402/L4661, CAGE 0JKF0, National Stock Number 3040-01-718-2303). The item weighs 83.6 pounds per unit pack with dimensions of 33.5 x 7.3 x 7.3 inches and has a cubic measurement of 1.033 cubic feet.

The packaging instruction mandates specific preservation and preparation steps including filling the cylinder with operational fluid, applying MIL-PRF-10924G preservative to all unpainted and unplated metallic surfaces and grease fittings, and sealing all interior openings with NAS 847 caps and plugs. The cylinder must be wrapped in MIL-PRF-121 Type II paper (24 x 36 inches) and secured with tape. Blocking and bracing consists of one piece of 2 x 4 x 12 lumber, one piece of 2 x 4 x 6 lumber, and two pieces of A-A55057 Type A blocking measuring 4-1/4 x 6 x ½ inches thick. The final unit container is an ASTM-D6880 Class 2, Standard Type 1 box measuring 30-1/2 x 5-3/4 x 4-1/4 inches. All preservation, packing, and container assembly must comply with MIL-STD-2073-1, MIL-STD-1186, and MIL-STD-129 standards. The document includes detailed diagrams illustrating the proper arrangement of blocking materials and cylinder placement within the shipping container.
