Shallow approach angle — precise application in hard-to-reach areas, tight spaces, and low-profile joint interfaces

Controlled medium bead — accurate dispensing without dripping or inconsistency for critical applications

Optimal versatile reach — deeper access than 2.0" nozzles while maintaining compact control vs. longer lengths

Pneumatic & manual dispensing guns — works seamlessly with both gun types for complete workflow flexibility

The precision-molded 30° angled tip facilitates precise application in hard-to-reach areas and tight spaces where straight nozzles cannot perform effectively. The shallow 30° approach angle enables optimal material flow in confined access zones — delivering accurate placement at low-profile joint interfaces, recessed cavities, and angled assembly areas. The 30° geometry provides a lower-profile approach angle vs. steeper 45° nozzles — ideal when minimal tip deflection, close parallel access, and precise dispensing at shallow angles are required. Combined with the 3.0" length, the 30° tip delivers shallow-angle precision at versatile reach depth — the defining advantage of the Model #640 over shorter angled nozzles.

The 1/8" orifice ensures controlled material flow for accurate dispensing — delivering a consistent, medium-diameter bead across a wide range of adhesives, sealants, and specialized materials. The precision orifice geometry ensures smooth, uniform material output without dripping or inconsistency. The 1/8" medium orifice bridges the gap between fine-precision nozzles (1/16") and wider-flow nozzles (1/4"+) — making the Model #640 the preferred choice for applications requiring controlled medium bead output at the 30° shallow approach angle in aerospace, defense, and industrial environments. For different flow requirements, the Semco® nozzle system is available in multiple orifice sizes.

At 3 inches in length, the Model #640 offers optimal reach for versatile use across a wide range of dispensing tasks. The 3.0" length provides deeper access than 2.0" nozzles while maintaining compact control vs. longer 4.0"+ lengths — delivering the ideal mid-range reach for standard industrial and aerospace dispensing operations. Combined with the 30° angled tip and 1/8" orifice, the 3.0" length creates a complete precision dispensing geometry for consistent, reliable performance across various tasks and environments. For applications requiring greater or lesser reach, the Semco® nozzle system is available in multiple lengths.

The Model #640 works seamlessly with both pneumatic and manual dispensing guns — providing complete workflow flexibility across all operating environments. Use with pneumatic dispensing guns for consistent, controlled high-volume material feed in production environments, or with manual dispensing guns for portable, direct operator control in field applications. Pair with pneumatic hoses for reliable pressure delivery — creating a complete, optimized Semco® dispensing system for consistent, reliable performance in your most demanding applications.

Complete your dispensing system with Semco® cartridges — compatible across the full range from 1 oz through 1/10 gallon. Protect your materials between dispensing sessions with Semco® end caps to prevent material cure and contamination, and cap seals for airtight cartridge protection that maintains material integrity and extends shelf life. The complete Semco® dispensing system delivers consistent, reliable performance across every component — from nozzle to cartridge to gun.

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.
