[Wei Tech] High Performance Green Gas 2X (800ml) Extra Large

Description:

WE 2X High Performance Premium Green Gas (800ml) is a popular premium propellant (commonly called "green gas") designed specifically for gas blowback (GBB) airsoft guns.

It is produced by WE-Tech (also stylized or referred to as WE, Wei Tech, or Wei/Tech), a well-known Taiwanese airsoft brand that makes GBB replicas and accessories. The 2X formula is one of their flagship gases and has been a favorite in the Asian airsoft scene for years. It is now widely available in Europe (with some versions manufactured in the EU).

Base: Propane-based green gas with an optimized admixture of silicone oil
Container: Matte aluminum can with a durable polymer nozzle (helps prevent damage to magazine valves/seals during filling)
Additives: High-performance silicone lubricant that fights corrosion/rust and greases internal moving parts
Temperature Range: Multi-season use — performs well even in cooler conditions down to about 5°C
Other: CFC-free, environmentally friendlier formulation

 

What Makes It Stand Out

High consistency and shot-to-shot repeatability — Ideal for competitive play (e.g., IPSC-style airsoft) because it delivers stable FPS and reliable cycling.

Excellent lubrication & protection — The built-in silicone oil keeps seals and metal internals in good condition, extending the life of your GBB pistol, rifle, or even gas grenades.

Smooth blowback performance — Powers blowback systems effectively without excessive wear when used in compatible guns.

Authenticity features — Original cans include a manufacturer’s hologram sticker to help distinguish them from counterfeits (fakes have been an issue in the market).

 

Compatibility & Warnings

It works with all standard green-gas airsoft replicas (pistols, carbines, SMGs, grenades, etc.). However, because of its higher power/pressure, manufacturers generally do not recommend it for replicas with full polymer (plastic) slides or frames — it’s best suited for metal-slide guns.

 

What the Community says

Players praise it for reliable performance, good cold-weather behavior, and the fact that it keeps replicas running smoothly over long sessions. It’s often compared favorably to other popular green gases in chrono and field tests.

Note: Always use airsoft green gas in properly maintained, rated airsoft guns only. Store the can upright in a cool, dry place away from direct sunlight or heat sources, and follow all safety instructions on the label (flammable gas under pressure).
