Shallow approach angle — precise application along flat surfaces, shallow joints, and wide-area assemblies where low-profile access is required

Controlled medium bead — versatile flow profile for a wide range of applications from adhesives to sealants

Maximum angled reach — deep cavity access and complex equipment navigation, longest in the #640 angled series

Pneumatic & manual dispensing guns — flexibility for different operational needs across all environments

The precision-molded 30° angled tip facilitates precise application — ensuring that materials are dispensed exactly where needed, reducing waste and improving efficiency. The 30° shallow approach angle provides a low-profile geometry — ideal for applications where a gradual, controlled approach is required at the dispensing surface. The 30° angle delivers a shallower approach than 45° nozzles — the preferred choice when low-angle access is required along flat surfaces, shallow joints, and wide-area assemblies. The 30° tip combined with the 6.0" extended length creates a maximum-reach precision dispensing geometry for the most demanding deep-access applications in aerospace, defense, and industrial environments.

The 1/8" orifice allows for controlled material flow — making it suitable for a wide range of applications, from adhesives to sealants. The 1/8" orifice delivers a controlled medium bead profile — providing greater material throughput than fine orifice configurations while maintaining precise flow control. The versatile 1/8" geometry ensures smooth, uniform dispensing without dripping or inconsistency across a broad range of material viscosities. The 1/8" orifice combined with the 6.0" extended length and 30° shallow approach delivers a complete precision dispensing geometry for versatile industrial applications. For different flow requirements, the Semco® nozzle system is available in multiple orifice sizes.

At 6 inches in length, the Model #640 provides the perfect reach for accessing tight spaces and hard-to-reach areas — helping users navigate complex equipment setups with ease. The 6.0" extended length is the longest in the Model #640 angled series — delivering significantly deeper access than the 3.0" and 4.5" configurations for deep cavity access, extended reach dispensing, and complex industrial equipment. Whether working in deep assembly joints, long-reach cavities, or complex industrial equipment, the 6.0" length provides the maximum reach advantage needed for consistent, reliable dispensing performance. For applications requiring different reach, the Semco® nozzle system is available in multiple lengths.

The Model #640 is compatible with both pneumatic and manual dispensing guns — offering flexibility for different operational 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 dispensing and creating a complete, optimized Semco® dispensing system for consistent, reliable performance.

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 bead geometry from prior use. The disposable format is the preferred choice for critical aerospace, defense, and industrial dispensing operations where material purity and application consistency are non-negotiable.
