Dual-Cartridge Applicator for 50 ml Cartridges

The Loctite 720228 is a manually operated meter-mix dispenser designed for 50 ml dual-cartridge adhesives. It accepts 1:1 and 2:1 mixing ratios using the included interchangeable plungers. The tool suits technicians and assemblers who need precise, on-demand dispensing of two-part materials.

Manual Operation With No External Power

The applicator relies entirely on hand force to advance the plungers, so it draws no electricity and produces no motor noise. Thermal output is negligible during normal use. The silver plastic housing insulates the user from the cartridge temperature during extended dispensing sessions.

Silver Plastic Housing With Stepped Tip Nozzle

The lightweight plastic body resists corrosion from common adhesive chemistries and cleans easily between jobs. A stepped tip with a Luer slip end fits standard mix nozzles without adapters. The package includes both 1:1 and 2:1 plungers, while compatible manufacturer part number 983531 identifies replacement cartridges.

Questions about this item

How do I install the correct plunger for the 1:1 or 2:1 mixing ratio on this Loctite 720228 applicator?

Select the supplied 1:1 or 2:1 plunger that matches your cartridge ratio, align its tabs with the housing slots, and press firmly until it clicks; the step users miss is verifying the plunger ratio marking against the cartridge label before loading.

Which wearable parts will need replacement after repeated use of this 50 ml dual-cartridge dispenser?

The stepped-tip mixing nozzles and Luer-slip adapters are consumables; swap them when the mix pattern becomes uneven or material cures inside the tip.

What limit appears first during continuous dispensing with the 720228 manual meter-mix gun?

Hand fatigue from sustained trigger force on the manually operated mechanism typically limits run length before the plastic housing or plungers show stress.
