RADCOLUBE LTGO (Low-Temperature General / Ordnance Lubricating Oil) is a high-performance synthetic lubricating oil specifically engineered for automatic weapons, small arms, aircraft ordnance systems, and defense machinery operating under severe arctic and sub-zero thermal conditions. Manufactured in strict accordance with military specification MIL-PRF-14107D and NATO code O-157, Radcolube LTGO provides exceptional low-temperature fluidity, low-volatility synthetic lubrication, and robust corrosion prevention across extreme thermal ranges (-54°C to 121°C). Formulated to prevent firing mechanism binding, carbon buildup, and gumming, LTGO ensures immediate cycling reliability and smooth mechanical operation in military weapon systems, airframe pintle mounts, and exposed defense equipment deployed in arctic or high-altitude environments.

Approved Specifications & Military Conformance:

Radcolube LTGO holds official Quality Products List (QPL) status under defense and NATO military standards:

• MIL-PRF-14107D QPL Certified: Fully qualified under military standards for low-temperature weapons and ordnance lubrication.
• NATO O-157 Specification: Standardized across NATO allied defense forces for arctic weapons lubrication and low-temperature mechanical maintenance.
• Extreme Sub-Zero Cycling Reliability: Formulated specifically to prevent weapon stoppages, sluggish bolt movement, and firing pin lag in sub-zero operational theaters.

Key Features & Performance Benefits

• Sub-Zero Arctic Mobility: Maintains low viscosity down to -54°C, preventing oil thickening and mechanical freezing during arctic maneuvers or high-altitude flight exposure.
• Carbon & Residue Resistance: Prevents heavy carbon fouling and varnish buildup on firing pins, bolts, gas pistons, and slide rails.
• Advanced Rust & Corrosion Inhibition: Shields internal steel and alloy surfaces against moisture condensation, rain, and atmospheric corrosion during field operations.
• Low-Torque Mechanical Response: Delivers instantaneous sliding friction reduction in low-power mechanical links, recoil slides, and weapon feeding mechanisms.

Typical Applications

• Aircraft Ordnance & Pintle Mounts: Primary low-temperature lubricant for airborne automatic cannons, rotary guns, ammunition feeders, and flexible pintle mounts.
• Military Small Arms & Crew-Served Weapons: Used for cleaning, lubricating, and preserving rifles, machine guns, and grenade launchers in cold-weather combat environments.
• Low-Temperature Defense Mechanisms: Ideal for exposed mechanical latches, remote weapon stations (RWS), and optical mount mechanisms operating in sub-zero climates.

2. Inventory Management (FIFO)
All products with an expiration date are managed and shipped on a strict "First In – First Out" (FIFO) basis.

3. Minimum Shipping Margin
Standard Guarantee: We will not ship any products with fewer than 30 days of use remaining (days before expiration), unless previously coordinated and agreed upon with the customer.

No Automatic Guarantees: Outside of this 30-day minimum margin, Aircraft Shop Supply does not make any automatic guarantee as to the specific length of time remaining on any shelf-life item for standard orders.

4. Special Customer Requirements
We understand that certain projects, maintenance schedules, or regulatory standards require strict specifications. If your order has specific shelf-life requirements, please proceed as follows:

How to Request: If you require a specific Date of Manufacture (DOM), Date of Expiration (DOE), or a specific minimum shelf-life percentage (%), you must clearly state this requirement:

In the Comments/Notes section when placing an online order.

Explicitly written on your Purchase Order (PO) or quote request email for offline orders.

Validation Process: Once your requirement is received:

We will ship your order if the available stock matches your specifications.

If we do not have the exact batch, we will contact you prior to shipping with the shelf-life percentage (%) or dates we have available for your acceptance.
