Their hardest-hitting gas, in the silicone-free blend. Roughly 200psi for full-metal guns in proper cold, with no oil carried along for the ride.

Black is the top of Nuprol's pressure ladder, somewhere near 200psi at room temperature. It exists for freezing mornings, when everything lighter leaves a gas gun short-stroking and miserable. In the right platform on the right day it is the difference between playing and packing up.

The ZERO blend removes the silicone from that equation. You still get the pressure; what you no longer get is oil arriving with every fill. Whether that matters to you depends on whether you would rather manage lubrication deliberately.

Treat the pressure with respect. This can is not a general-purpose choice, and it is not a way to squeeze more out of a gun that was never built for it.

Frequently asked questions

What separates this from the 4.0? Nothing in the pressure. The silicone has been left out, so seal lubrication is a job you now own.

Is my gun rated for it? If you are not certain, ask before you buy. Putting this through a platform that cannot take it is an expensive way to find out, and it is not a warranty claim.

Should I run it all year? There is little reason to. It was designed for cold, and a lower grade will be kinder to the gun the rest of the time.

How do I keep the seals healthy? Apply silicone grease yourself, and do it as a habit rather than a rescue job once something starts leaking.

⚠ High pressure and no silicone, so two separate cautions apply. Only use it in a full-metal gas gun rated for high-pressure gas — never in an ABS or plastic-slide pistol, where it can cause real damage. Separately, nothing in this can is lubricating anything, so seals want attention on a schedule.
💡 Titan Forge Airsoft tip: Flammable and under pressure: keep cans below 50°C and out of direct sunlight. If winter is not the problem you are solving, a milder grade in gas will treat the gun better.
