Turn your M18 grease gun into a no-mess, screw-and-go unit.
This OxRock-designed adapter lets you convert your Milwaukee M18 (Australia/NZ models), AEG, or Metabo 18V grease gun from old 450g pull-off cartridges to the new 500g KAJO screw thread cartridges. No more metal barrels. No more messy plungers. Just cleaner, faster greasing with less downtime.
Why tradies dig it:
• Converts 450g grease guns to 500g KAJO screw cartridges
• Cleaner, hassle-free cartridge swaps – no plunger needed
• CNC-machined for perfect fit with a 24mm socket
• Installs permanently with 25Nm torque – set and forget
• No bleeding required after first prime
• Durable and workshop-tough – made for real-world use
Top Tip:
When changing cartridges, press the white plunger until grease exits the top to remove air pockets and avoid dry spots.
How It Works:
- Remove the metal cartridge from your Milwaukee grease gun.
- Insert the OxRock adapter using a 24mm socket.
- Torque to 25Nm – the adapter stays in the gun permanently.
- Insert the 500g KAJO screw thread cartridge.
- Prime by pressing down on the cartridge while holding the bleed button. Repeat until grease exits the bleeder.
- You’re ready to grease – no further bleeding required.
Compatible With:
• Milwaukee M18 grease guns (AU/NZ models only)
• AEG and Metabo 18V grease guns
