Known backups / known substitutes
- Nordson TAH 190-620 (7701487): A similar Nordson TAH 190 series mixer, but typically features a stepped tip rather than the H-tapered Luer-Lok compatible outlet.- Infinity Bond 190-620 Adhesive Static Mix Nozzle: A compatible aftermarket alternative designed to offer similar performance.- Chem-Set 160-624 Static Mixing Nozzle: Another potential substitute from a different brand.- Other Nordson EFD Series 190 mixers: Variations within the same series may offer different element counts or tip configurations.- Static mixers from other manufacturers: Brands like Sulzer Mixpac, Medmix, Newborn Brothers, ASI, Albion, Polytek, Quality Aerosols, and other generic bayonet-style static mixers for 50ml cartridges can serve as alternatives depending on specific application requirements.
Comparison Note
The Nordson TAH 190-620H (7701510) stands out within the 190 series due to its specialized H-Tapered tip with Luer-Lok compatibility. This feature provides superior precision and control during dispensing, making it ideal for applications requiring fine bead placement, in contrast to the standard stepped or full-bore tips found on other 190 series mixers like the 190-620 (7701487). Its 20-element round-helix design consistently delivers excellent mixing performance for a broad spectrum of two-component adhesives, particularly those with medium to high viscosities.
