Description
The Cox PPM 300 XL is a hand powered applicator for two component side by side cartridges, sold by medmix under the Cox dispensing brand. It handles 375, 450, and 600 mL cartridges and ships as a multi-ratio kit with the inserts needed to run 1:1, 2:1, and 4:1. A 25:1 mechanical advantage, wear compensating drive, and sintered steel catch plate keep output steady on high viscosity adhesives and sealants with no air line required.
This gun has been sold under several names over the years. If you are looking for the Cox M300XL, the DM2 M300XL, or medmix part number 159288, this is the same tool.

Performance in Production
- 25:1 mechanical advantage and 1011 lbf maximum force support thick, high viscosity epoxies, acrylics, and urethanes by hand.
- Wear compensating device holds thrust on the rod as the tool sees repeated use, which keeps output consistent through a shift.
- Sintered steel catch plate resists slipping under load on stiff material.
- Support discs seat the cartridge squarely so both sides advance evenly and the mix ratio stays correct.
- Multi-ratio kit lets one gun cover 1:1, 2:1, and 4:1 cartridge formats instead of stocking three guns.
- 3.7 lb tool weight and no air line make it practical for field repair and moving between stations.
- Manual action gives direct control over flow, which helps on short shots and detail beads.
Common Applications
- Dispensing two component epoxies, acrylics, and urethanes from side by side cartridges
- Fabrication, assembly, and repair bench work
- Field repair where compressed air is not available
- High viscosity adhesive and sealant application
- Production areas running multiple cartridge ratios on one tool
