High-volume controlled flow — wide bead profile for large-area coverage, adhesives, sealants, and viscous fluids at maximum reach

Robust wide-body geometry — controlled expansion path for consistent uniform delivery through 6-3/16" extended length

Maximum extended reach — deep cavities, complex assemblies, industrial and automotive access beyond 4" configurations

Seamless connection — all Semco® cartridge sizes, 1 oz through 1/10 gallon, secure leak-free attachment

At 6-3/16 inches in length, the Model #8648 provides maximum extended reach for tight spaces and complex assemblies — crucial in industrial and automotive applications. The 6-3/16" extended length delivers significantly deeper access than the 4" Model #8646 — making it the preferred choice for deep cavity access, extended reach dispensing, and complex industrial equipment where maximum reach at high-volume flow is required. The 3-5/8" wide body combined with the 6-3/16" extended length creates a robust, high-volume extended reach dispensing geometry for the most demanding deep-access applications. For applications requiring shorter reach, the Semco® nozzle system is available in multiple lengths.

The wide 3/4" orifice is designed for controlled material flow — making it suitable for a wide variety of materials including adhesives, sealants, and other viscous fluids. The 3/4" orifice delivers high-volume material throughput for large-area coverage, wide bead profiles, and high-flow industrial dispensing — now at the maximum 6-3/16" extended reach distance. The 3-5/8" x 3/4" controlled expansion flow path ensures consistent, uniform material delivery from the wide body through to the 3/4" tip — whether dispensing high-viscosity adhesives, thick sealants, or specialized viscous fluids at depth in complex industrial equipment.

The precision-molded 1/4" NPT male thread allows for seamless connection to 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 male thread ensures a secure, leak-free connection between nozzle and cartridge — delivering consistent, reliable high-volume material flow at every dispensing operation. The 1/4" NPT thread is the industry-standard connection for Semco® dispensing systems — ensuring maximum compatibility, secure attachment, and optimal performance across all compatible cartridge sizes and dispensing gun configurations.

The Model #8648 is compatible with both pneumatic and manual dispensing guns — giving you the flexibility to choose the best dispensing method for your specific needs. Use with pneumatic dispensing guns for automated dispensing with speed and efficiency for high-volume applications, or with manual dispensing guns for detailed work allowing hands-on control and precision in every application. Pair with a pneumatic hose for extended reach capability — making it easier to access hard-to-reach areas during high-volume dispensing at the 6-3/16" maximum reach distance.

Complete your dispensing system with Semco® cartridges — high-quality cartridges specifically designed for optimal performance, compatible across the full range from 1 oz through 1/10 gallon. Protect your dispensing system and maintain cleanliness with reliable end caps that prevent contamination. Ensure airtight seals to preserve the integrity of your materials and enhance shelf life with Semco® cap seals. The complete Semco® dispensing system delivers consistent, reliable performance — ensuring your projects are completed successfully and efficiently.

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, automotive, and aerospace dispensing operations where material purity and application consistency are non-negotiable.
