What it is

The 4uantum Heat Resistant Gear Lubricant Pen is a specialist grease developed for the gears inside AEG gearboxes. Gears are high-speed rotating mechanisms, and as speed climbs so does temperature, so they need a lubricant built to cope.

Made for heat

This high-temperature gear protection oil provides excellent viscosity while withstanding high temperatures, still offering enough gear-surface lubrication to protect your gears and reduce noise. The result is a smoother, longer-lasting gearbox.

For demanding builds

It maintains adhesion even at extreme temperatures, making it suitable for standard gear ratios as well as high-stress DSG and TSG setups where heat is a real concern.

Clean, controlled application

The special twist and brush design not only makes the pen easy to clean but also ensures you use the minimum amount of grease for the most effective lubrication. Pair it with the rest of the 4uantum range in our airsoft accessories, or let our Kent repair service service your gearbox.

Frequently asked questions

What is this grease designed for?

It is a high-temperature gear protection oil developed for the gears inside an AEG gearbox, where high-speed rotation generates heat that thinner lubricants cannot handle.

Why not just use a general oil on gears?

Gears are high-speed rotating mechanisms that build heat, so they need a viscous, heat-resistant grease. A thin oil can sling off and fails to protect the gear surfaces under load.

Does it make the gearbox quieter?

Yes. As well as protecting the gear surfaces at temperature, it helps reduce gear noise, giving a smoother running gearbox.

Is it suitable for high-speed builds?

It is designed to maintain adhesion even at extreme temperatures, so it suits demanding setups including DSG and TSG gearboxes as well as standard ratios.

How do I apply it neatly?

The twist and brush pen design lets you paint on just the minimum amount needed for effective lubrication, keeping application clean and controlled with no mess.
