Product Name
Nordson Series 260 Wide Mixing Nozzle for Thick Material (24-element 11.7 in 7701770 and 18-element 9.1 in 7701758) x 13mm Inner Diameter ID
Brief Description
The Nordson Series 260 Wide Mixing Nozzle is a disposable static mixer specifically engineered for the efficient and homogeneous blending of two-part, high-viscosity adhesives, sealants, and coatings. Featuring a spiral mixer design and a wide inner diameter, these nozzles are ideal for challenging thick materials such as epoxies and polyurethanes, ensuring thorough mixing before dispensing.
Popular Applications & Uses
- Mixing two-part epoxies, polyurethanes, silicones, acrylics, methacrylates, and polysulfides.- Dispensing high-viscosity (thick) adhesives and sealants.- Applications requiring a consistent and homogeneous mix of two-component materials.- Used with standard C-System 200ml, 400ml, 600ml, and 1500ml 2-part adhesive cartridges in various ratios (1:1, 2:1, 4:1, 10:1).
Industries that Commonly Use It
- Aerospace/Defense (e.g., aircraft assembly)- Automotive Service/Repair- Cabinet & Woodworking- Chemical Industry- Construction/ Building Services (e.g., home building, concrete repair)- Countertop- Distributers & Resellers- Electrical Services or Products- Energy (e.g., wind turbine assembly and repair)- Engineering Services- Fabrication- General Manufacturing (for assembly processes)- Government & Military- Industrial Supply- LED/Electronics- Marine- Medical Device/ Prosthetics (for precision dispensing in medical applications)- Metal Fabrication- Mold Making/ Casting- Plastic Fabrication- Pool/Spa/Plumbing- Sign & Display- Special Effects/ Scenic Design- Transportation/ Specialty Vehicle
Special and Unique Features
- Specifically designed for thick, highly viscous materials.- Features a wide helix (round) nozzle with an approximate 1/2 inch (12.8mm/13mm) inner diameter.- Equipped with a bell-style inlet for universal compatibility with a broad range of standard adhesive cartridges.- Includes a stepped outlet tip that can be cut to adjust the dispensed bead size.- Available in two lengths: 18-element (9.1 inches / 23.11 cm) and 24-element (11.7 inches / 29.72 cm) for optimized mixing performance.- Both the mixing elements and housing are constructed from durable polypropylene.- Disposable design eliminates the need for cleaning, making it cost-effective and suitable for applications involving multiple adhesive types.
Key Properties

Surface Compatibility
The nozzle itself is made of polypropylene. The adhesives and sealants mixed by this nozzle are compatible with a wide range of substrates, including but not limited to, metals, plastics, concrete, wood, and various composite materials, depending on the specific adhesive chemistry being used.
Known backups / known substitutes
- Other static mixing nozzles from Nordson EFD, including different series or element counts.- Static mixer nozzles from alternative manufacturers, such as Infinity Bond ThickMIX or Sulzer Mixpac MS/ME Series.- Various dispensing tips designed for different fluid viscosities, such as Nordson EFD SmoothFlow tapered dispense tips for medium-to-high viscosity fluids.
Comparison Note
The Nordson Series 260 Wide Mixing Nozzles are specifically engineered for challenging thick, high-viscosity, two-part materials, setting them apart from nozzles designed for lower viscosity fluids or hot melt applications. Their wider diameter and higher element count (18 or 24) are crucial features that ensure a thorough and homogeneous mix with demanding thick materials, where standard or smaller diameter nozzles would be less effective. The bell inlet design provides broad compatibility with common large-volume adhesive cartridges.
