More Than Storage.
Preservation.
The Sentinel Vault is a sealed preservation system. Flush the interior with nitrogen or argon to displace oxygen, then lock it down. Firearms, ammunition, optics, and sensitive equipment stay corrosion-free in a controlled atmosphere, whether it’s stored in your closet, staged in a vehicle, or staged at the range.
Inert Gas Flush System
The Sentinel Vault is equipped with dual gas valves that allow you to displace oxygen inside the sealed chamber with an inert gas such as nitrogen or argon. By removing oxygen, you halt oxidation, corrosion, and biological degradation, keeping firearms, documents, electronics, and sensitive equipment in the same condition as the day you sealed them. Connect a standard gas regulator to the input valve, flush until the atmosphere is displaced through the output valve, then close both valves and latch the lid. The IP67 gasket holds the seal indefinitely.
- Load items and arrange inside the vault
- Connect gas regulator to the input valve
- Flush until inert gas displaces oxygen through the output valve
- Close both valves, latch the lid, and seal
How You Use It
One system, multiple missions. The Sentinel Vault adapts to how and where you need it.
Long-Term
Firearms Storage
Flush with nitrogen, seal the latches, and store for months. No oil baths, no desiccant packs, no constant maintenance. The oxygen-free environment does the work.
- Eliminates rust and oxidation without chemical treatments
- Customizable foam inserts hold firearms in position
- Lockable latches for secure home or facility storage
Ammunition
Preservation
Oxygen degrades primers and powder over time. An inert gas environment stops that process entirely, extending the reliable shelf life of your ammunition stockpile.
- Prevents primer and powder degradation from oxygen exposure
- Watertight seal protects against humidity and moisture
- 135L capacity holds significant ammunition volume
Optics & Sensitive
Equipment
Night vision devices, scopes, rangefinders, and electronics are vulnerable to moisture and oxidation. The Sentinel Vault creates the same controlled atmosphere used in professional equipment storage.
- Oxygen-free environment prevents lens fungus and coating degradation
- Foam inserts protect against impact and vibration
- Climate-resistant shell for garage, vehicle, or facility storage

135L Organized
Interior
The interior is fully customizable. Pick-and-pluck foam inserts allow you to shape the layout to fit your exact inventory. The sealed gasket ring and pressure-equalization valve maintain atmosphere integrity after every gas flush.
- Pick-and-pluck customizable foam inserts
- Pressure-equalization valve for altitude and temperature changes
- IP67-rated gasket seal around full perimeter
- Dual gas input/output valves integrated into shell
- Stackable with additional Sentinel Vault units
