Steeper approach angle — accurate placement in hard-to-reach areas where direct perpendicular access is obstructed

Fine-to-medium controlled bead — consistent flow without dripping, increased throughput vs. 1/32" ultra-fine

Optimal compact reach — greater depth than 1-1/2" nozzles while maintaining tight-zone access and control

Pneumatic & manual dispensing guns — operates seamlessly with both gun types for optimal performance

The precision-molded 45° angled tip enables accurate placement and consistent bead application even in hard-to-reach areas. The 45° geometry provides the ideal balance between access angle and tip control — enabling precise bead placement at joint interfaces, recessed cavities, and angled assembly areas. The 45° angle delivers steeper deflection than 30° nozzles — ideal when direct perpendicular access is obstructed and a steeper approach angle is required. The 45° tip combined with the 2.0" compact length creates a precision dispensing geometry that excels in tight, confined access environments in aerospace, defense, and industrial applications — providing greater reach depth than the 1-1/2" configuration while maintaining compact control.

The precise 1/16" orifice diameter delivers controlled material flow — producing a fine-to-medium, consistent bead for demanding dispensing applications. The orifice geometry ensures smooth, uniform dispensing of adhesives, sealants, potting compounds, and other specialized materials without dripping or inconsistency. The 1/16" orifice provides increased material throughput vs. the 1/32" ultra-fine configuration — making it the preferred choice for applications requiring controlled flow with a slightly wider bead profile at the 45° approach angle. For finer bead requirements, the Model #420 is also available with a 1/32" ultra-fine orifice.

At 2 inches in length, the Model #420 provides optimal reach — ideal for tight access zones and confined spaces. The 2.0" length provides greater access depth than the 1-1/2" configuration while maintaining compact control — delivering fine bead accuracy in restricted access environments with slightly extended reach. Whether working in tight assembly joints, confined cavities, or restricted access zones, the 2.0" compact length ensures precise material placement without obstruction. The 2.0" length combined with the 45° angled tip and 1/16" orifice creates a complete precision dispensing geometry for consistent, reliable performance. For applications requiring greater reach, the Semco® nozzle system is available in multiple lengths.

The Model #420 operates seamlessly with both pneumatic and manual dispensing guns for optimal performance. Use with pneumatic dispensing guns for consistent, controlled material feed in production environments, or with manual dispensing guns for portable, direct operator control in field applications. Pair with a pneumatic hose assembly for reliable pressure delivery — creating a complete, optimized Semco® dispensing system for consistent, reliable performance in your most demanding applications. The Model #420 is engineered to deliver exceptional precision and consistency across every gun type and operating environment.

The Model #420 securely attaches to any compatible Semco® cartridge — compatible across the full range from 1 oz through 1/10 gallon. The secure cartridge attachment ensures leak-free, reliable material flow from cartridge through nozzle to application point — delivering consistent, precise bead output at every dispensing operation. Semco® disposable cartridges are required to complete your dispensing system and ensure optimal Model #420 performance.

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.
