Nordson 7700811 TAH 160-416 Static Mixing Nozzle

Description

The Nordson 7700811 static mixer is a Series 160 spiral bell nozzle for compatible two-part cartridges. It combines a bell inlet, 16-element helical core, and slip-luer outlet in the TAH 160-416 configuration. Select it by connection style, cartridge interface, element count, length, and outlet geometry rather than by appearance alone, because nearby mixer families can look similar while using different attachment systems.

Static Mixer Fitment and Compatibility

The mapped Nordson fitment sheet identifies manufacturer part number 7700811 and legacy configuration 160-416. Its bell connection is intended for compatible bellmouth cartridge systems. The sheet associates this configuration with 1:1, 2:1, 4:1, and 10:1 ratios, but ratio alone does not confirm fit. Cartridge outlet geometry, retaining method, adhesive viscosity, backpressure limits, and the dispensing setup must also match.

The internal element is a helical design with 16 elements. Housing outside diameter is 0.300 inch and housing length is 3.90 inches. The outlet is a slip luer, which supports precise placement or attachment of a compatible dispensing tip. Confirm that the luer accessory and material path are suitable for the adhesive being dispensed.

Static Mixer Buying Format

This SKU is sold as an individual nozzle. It is useful for replacement, process qualification, short runs, and workcells that need a defined mixer configuration without purchasing an unrelated cartridge kit. Treat each nozzle as a wetted disposable component. Once mixed adhesive cures inside the element, flow and ratio quality cannot be restored by pushing fresh material through the hardened path.

Before a production run, verify the full part number against the cartridge and dispenser bill of materials. Purge the two components evenly before installing the nozzle when the adhesive procedure calls for it, then dispense an initial mixed amount according to the material supplier’s instructions. Watch for uneven color, streaking, excess pressure, leakage at the bell, or interrupted flow. Those signs can indicate incorrect seating, a blocked outlet, off-ratio feed, or a mixer that is too restrictive for the process.
