Jet Fuel JP-8 (NATO F-34) Storage & Tank Compatibility

Storing Jet Fuel JP-8 (NATO F-34)? Start Here

Jet Fuel JP-8 (NATO code F-34) is a kerosene-based aviation turbine fuel manufactured to the U.S. military specification MIL-DTL-83133. It is a complex petroleum distillate — more than 200 aliphatic and aromatic hydrocarbons spanning roughly nine to seventeen carbon atoms — with aliphatic compounds making up about 80% of the blend. Three to six performance additives are required during manufacture, including a corrosion inhibitor / lubricity improver (CI/LI), a fuel system icing inhibitor (FSII), and a static dissipater additive (SDA).

JP-8 powers military aircraft and, in the field, ground vehicles and generators under a single-fuel-forward concept. Because it is a flammable hydrocarbon distillate, material of construction (MOC) selection is governed by permeation and stress-cracking behavior rather than acidity. Choosing the wrong tank polymer leads to fuel weeping, wall swelling, and brittle failure — which is why JP-8 is stored in steel, stainless, fuel-grade FRP, or aluminum, never in a standard polyethylene tank.

Is Polyethylene (HDPE / XLPE) Safe for JP-8?

No — polyethylene is not suitable for storing JP-8. Like all petroleum fuels, JP-8 permeates polyethylene over time, causing the resin to swell, soften, and lose dimensional stability. More critically, contact with gasoline, kerosene, and other hydrocarbons drives environmental stress cracking in polyethylene, a surface-initiated brittle failure mode. Published HDPE chemical-resistance charts rate jet fuel (JP-3/JP-4/JP-5/JP-8) as having a severe effect on HDPE. Crosslinked polyethylene (XLPE) offers somewhat better stress-crack resistance than HDPE but is still not rated for long-term primary fuel storage. For JP-8 service, specify a steel UL-142 / API tank, stainless steel, a fuel-grade fiberglass (FRP) tank, or aluminum, with PTFE/FKM or qualified nitrile seals.

Material compatibility at a glance

JP-8 is a petroleum distillate fuel, so the dominant compatibility driver is hydrocarbon permeation and environmental stress cracking, not corrosion or pH. Polyethylene (HDPE/XLPE) is unsuitable for primary storage: fuel permeates the wall, swells the resin, and accelerates stress cracking. Specify steel (UL-142 / API), stainless, fuel-grade FRP, or aluminum with fluoropolymer or qualified nitrile seals.

Ratings: S suitable · C conditional / limited · U unsuitable. Verify against the cited resistance charts and your concentration/temperature before specifying.

The safety that actually matters

• Flammable liquid (H226): flash point about 38°C (100°F); vapors can travel to an ignition source and flash back — bond and ground all transfer equipment and control static.
• Aspiration hazard (H304): may be fatal if swallowed and drawn into the lungs — never siphon by mouth; do not induce vomiting.
• Skin and CNS effects (H315, H336): causes skin irritation and repeated contact defats skin; vapors may cause drowsiness or dizziness — use gloves, goggles, and adequate ventilation.
• Carcinogenicity concern (H351): suspected of causing cancer; minimize dermal and inhalation exposure and follow occupational exposure limits.
• Aquatic toxicity (H411): toxic to aquatic life with long-lasting effects — provide secondary containment and prevent releases to soil, drains, and waterways.
• Static accumulation: JP-8 carries a static dissipater additive, but high flow rates still build charge — observe approved fueling, bonding, and grounding procedures.

Common questions

Can I store JP-8 jet fuel in a poly (HDPE or XLPE) tank?

No. JP-8 is a petroleum distillate fuel that permeates and swells polyethylene and promotes environmental stress cracking. Published resistance charts rate jet fuel as a severe effect on HDPE. Use a steel UL-142 / API tank, stainless, fuel-grade FRP, or aluminum instead.

What is JP-8 made of?

JP-8 is a kerosene-based blend of more than 200 aliphatic and aromatic hydrocarbons (roughly C9–C17), about 80% aliphatic, plus required additives: a corrosion inhibitor / lubricity improver, a fuel system icing inhibitor, and a static dissipater additive, all per MIL-DTL-83133.

What tank material is recommended for JP-8?

Carbon steel built to UL-142 or API standards is the industry norm, along with stainless steel, aluminum, or a fiberglass (FRP) tank made with a fuel-grade resin. Pair with PTFE/FKM seals or qualified nitrile, and avoid EPDM and polyethylene.

Is JP-8 flammable, and what is its flash point?

Yes. JP-8 is a flammable/combustible hydrocarbon liquid with a minimum flash point of about 38°C (100°F) per MIL-DTL-83133. Control ignition sources, bond and ground transfer equipment, and manage static during fueling.
