LORD Ratio-Pak Pneumatic Dispenser, 4:1

Description

The LORD Ratio-Pak pneumatic dispenser is **dispenser parts** equipment for 4:1 two-component adhesive packages. It helps move resin and hardener through the cartridge in the correct proportion, then feeds the material through a static mixer so the operator can apply a controlled bead for bonding or repair work.

### Where these dispenser parts fit

Ratio-specific pneumatic tools are used when a two-part cartridge package cannot be run correctly in a general applicator. A 4:1 package needs plunger geometry that advances the larger and smaller components together at the intended rate. If the gun does not match the ratio, the adhesive can cure soft, cure slowly, or develop weak spots because the mix is wrong before it reaches the joint.

This dispenser belongs in assembly cells, maintenance shops, transportation repair, metal fabrication, composite work, and sign or display production where LORD adhesive systems are applied from packaged cartridges. Pneumatic drive is useful when several beads are applied in sequence or when adhesive viscosity makes manual trigger pressure uneven over a full cartridge. Keep the matching mixing nozzle, 2 part mixing nozzle, and jb weld mixing nozzle inventory clearly labeled by ratio, diameter, and retained material family.

### How dispenser parts protect mix quality

Start by confirming the cartridge ratio, mixer type, and plunger set. Install the cartridge squarely, connect regulated air, and keep the gun pointed away from the work while purging both components to the nose. Add the mixer only after both sides are flowing. Dispense a short waste bead until the mixed material looks consistent, then apply the adhesive to the prepared substrate within the working time used by the shop.

During use, watch for sudden pressure changes, uneven bead color, or trigger response that feels different from the previous cartridge. Those signs can point to a blocked mixer, cold material, an unseated cartridge, or cured residue at the outlet. Replacing a mixer is usually faster than fighting back pressure through a partly blocked tip. Keep used mixers out of the storage bin so cured residue does not get mistaken for a clean part.
