3M 7000028616 Square Gold Mixing Nozzle 36 Per Case

Product Description

The 3M 7000028616 is a square-profile static mixing nozzle designed for use with two-part adhesive cartridge systems. The gold color designation and larger size format identify this nozzle for compatibility with specific 3M Scotch-Weld dispensing cartridges that require a larger-bore mixing element. Static mixing nozzles like this one blend two-component epoxies, acrylics, and urethanes internally as the material is dispensed, eliminating manual mixing and reducing waste. These nozzles are single-use components replaced after each application session to prevent cured adhesive from blocking the tip. Installers across HVAC, electrical, plumbing, and general mechanical trades rely on static mixing nozzles for structural bonding and gap-filling applications.

This nozzle is suited for professional and industrial adhesive dispensing where consistent mix ratio and repeatable bead quality are required. Typical applications include structural bonding of metal, plastic, and composite substrates in both residential and commercial settings. The square nozzle geometry is matched to cartridge systems that use a corresponding square outlet port. Sold individually, this SKU is drawn from a 36-piece case quantity, making it practical for shop stock or ongoing service work.

Key Features

• Static mixing element blends two-component adhesives internally for consistent mix ratio without manual mixing
• Gold color coding aids quick identification on the job site when multiple nozzle types are in use
• Single-use design prevents cured adhesive blockage between application sessions
• Lightweight at 0.03 pounds, minimizing added weight during overhead or confined-space work
• Available in a 36-piece case for convenient bulk stocking

Compatibility

Designed as an OEM-style replacement mixing nozzle for 3M Scotch-Weld two-part adhesive cartridge dispensing systems that accept a larger square-outlet nozzle format. Confirm cartridge outlet geometry and nozzle bore size before installation.

Installation Notes

Mixing nozzles are installed by trade professionals and assembly technicians familiar with two-component adhesive dispensing equipment. Before attaching the nozzle, verify the cartridge is properly seated in the dispensing gun and that the outlet ports are unobstructed. Twist-lock or bayonet-style attachment varies by cartridge system — follow the cartridge manufacturer's procedure to seat the nozzle securely before dispensing. Discard the nozzle immediately after use; do not attempt to clean and reuse static mixing elements, as residual cured adhesive can block the internal mixing helix.
