New Old Stock (NOS) factory sealed can of Military Standard MS3396-12 14mm thread aircraft engine storage dehydrator plugs.

Includes 22 individual plugs. As seen in the photos, the desiccant crystals are still bright blue/purple, confirming they are perfectly dry, active, and have not absorbed any ambient moisture.

These humidity indicator plugs are used by mechanics to thread into standard 14mm spark plug holes for long-term engine preservation, storage, and corrosion/rust protection. Essential for private aviation, airplane restoration, vintage aircraft, marine applications, and industrial mechanical storage.

Selling the entire lot together. Willing to ship for an extra fee or meet locally. Message me with any questions.
