Consistent flow rates — application accuracy across most demanding projects, repeatable reliable performance

The Model #620 delivers exceptional control through its precise 1/16" orifice diameter — providing pinpoint accuracy and controlled material flow for applications requiring the highest level of dispensing precision. The 1/16" fine orifice ensures consistent flow rates and application accuracy for adhesives, sealants, potting compounds, and other specialized materials across your most demanding projects. At 6.0" in length, the Model #620 delivers this fine controlled flow at maximum extended reach — the definitive choice for applications requiring pinpoint accuracy at depth in hard-to-reach industrial, aerospace, and electronics environments. Available in a comprehensive range of orifice dimensions for different flow requirements.

The generous 6.0" length allows for access to hard-to-reach application areas — making the Model #620 the maximum length configuration in the Semco® 1/16" fine orifice straight nozzle series. At 6.0", the Model #620 provides 50% more reach than the 4.0" Model #420 configuration — delivering fine controlled flow at depth in the most challenging industrial equipment, deep cavity assemblies, recessed joint areas, and hard-to-reach locations. The 6.0" length combined with the 1/16" fine orifice and 1/4" NPT male thread creates the ultimate precision extended reach dispensing geometry — delivering consistent, reliable pinpoint accuracy at the maximum reach distance in your most demanding applications.

The robust 1/4" NPT male thread connection seamlessly integrates with the complete range of Semco® disposable cartridges — including 1, 2.5, 6, 8, 12, 20, 32 oz, and 1/10th gallon sizes. The standardized 1/4" NPT connection ensures consistent, reliable performance — delivering fine controlled flow from cartridge through nozzle to application point at every dispensing operation. Optimize your dispensing system by pairing this premium nozzle with Semco® cartridges and either pneumatic or manual dispensing guns — creating an efficient and ergonomic dispensing solution for industrial applications.

Optimize your dispensing system by pairing this premium nozzle with either pneumatic or manual dispensing guns — providing flexibility based on your specific application requirements and operational preferences. Use with a pneumatic dispensing gun for high-volume or production applications requiring speed and efficiency, or with a manual dispensing gun for precision control in detailed work. For a complete professional setup, enhance your workflow with pneumatic hose accessories — creating an efficient and ergonomic dispensing solution for industrial applications at the 6.0" maximum extended reach distance.

The Model #620 represents the pinnacle of precision fluid dispensing technology — meticulously precision-molded to ensure consistent flow rates and application accuracy across your most demanding projects. The precision molding process ensures consistent wall thickness, dimensional accuracy, and uniform 1/16" orifice geometry across every unit — delivering repeatable, reliable fine bead output at the 6.0" maximum extended reach distance. Whether working with adhesives, sealants, potting compounds, or other specialized materials, the Model #620 ensures consistent, reliable performance in your most demanding industrial applications.

The disposable design ensures single-use application integrity — eliminating cross-contamination between materials and maintaining consistent dispensing performance across every application. Simply remove and replace for each new application — no cleaning, no residual material buildup, no compromised flow geometry from prior use. The disposable format is the preferred choice for critical industrial, aerospace, and electronics dispensing operations where material purity and application consistency are non-negotiable at the 6.0" maximum extended reach distance.
