Clean, controlled airsoft lubrication

The 4UANTUM Performance Lubrication Pen is a specialist maintenance tool for airsoft replicas, giving you precise, mess-free lubrication exactly where it is needed. Developed by 4UAD in collaboration with J-Smooth, it houses a high-performance lubricant inside a twist-pen applicator with an integrated brush tip.

A smarter formula

The lubricant is a blend of polydimethylsiloxane, PTFE (Teflon) and paraffin wax. Every ingredient is inert and non-toxic, making it safe to use on plastic and rubber parts as well as metal. The formula delivers high adhesion, high abrasion resistance and ultra-low friction for smoother, longer-lasting protection.

Where to use it

It is ideal for AEG gears, pistons and tappet plates, GBBR trigger parts and routine GBB pistol maintenance. Because it is not sticky it is less likely to attract dust and grit into your action.

Touch-free and portable

Twist the top to dispense, apply with the brush, then twist back to seal. The slim pen slips into any tech kit and keeps your hands clean during fiddly internal work. Browse more airsoft accessories or book a service at our Kent repair workshop.

Frequently asked questions

What is the 4UANTUM Lubrication Pen used for?

It applies a controlled amount of silicone-based lubricant to moving airsoft parts such as AEG gears, pistons, tappet plates, GBB seals and pistol slides, helping them cycle smoothly and resist wear.

Is it safe on plastic and rubber parts?

Yes. The formula is a blend of polydimethylsiloxane, PTFE and paraffin wax that is inert and non-toxic, so it will not corrode or degrade plastic or rubber components.

How do I dispense the lubricant?

Twist the top of the pen to feed lubricant to the brush tip, then apply it exactly where needed. Twist it back the other way to seal the pen when you are finished.

How often should I lubricate my airsoft gun?

Lubricate whenever the action feels less smooth, and always refresh rubber seals and moving parts after long storage. A quick clean and re-lube before games keeps performance consistent.

Can I use it inside a gearbox?

It is well suited to sliding contact points, but avoid spreading it across gear surfaces or inside the piston where it can fling around. For full gearbox servicing our workshop can help.
