The EMN22i is the static mixing nozzle for Simpson Strong-Tie SET-3G™ high-strength epoxy. Adhesive is blended as it passes through the internal helix, so the two components arrive at the hole fully mixed. Each cartridge ships with one nozzle; keep spares on hand, because a nozzle that has been left to cure cannot be reused.
The EMN22i does not fit AT-3G™, which uses the AMN19Q nozzle, or Strong-Bond™, which comes with its own nozzle.
No. Once adhesive cures inside the helix the nozzle is finished. Leave it on the cartridge as a cap, then fit a new one.
Plan on one per session, plus spares for interruptions. Adhesive left sitting in a nozzle sets quickly in warm weather.
No. AT-3G uses the AMN19Q nozzle.
Yes. SET-3G installations that must meet ICC-ES ESR-4057 or ESR-4844 have to be dispensed through the nozzle supplied by Simpson Strong-Tie. Do not substitute another manufacturer's nozzle.
