Shallowest in Semco® angled series — most gradual low-profile approach for flat surfaces and low-clearance joints

Bridges ultra-fine and medium — increased throughput with precise flow control, no dripping or inconsistency

Optimal compact reach — precise operator control at 20° shallow approach in confined access environments

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

The precision-molded 20° angled tip is the shallowest approach angle in the Semco® angled nozzle series — enabling accurate placement and consistent bead application even in hard-to-reach areas. The 20° geometry delivers the most gradual, low-profile approach — ideal for applications where an extremely shallow dispensing angle is required along flat surfaces, wide-area assemblies, and low-clearance joints. The 20° angle is shallower than both 30° and 45° nozzles — the preferred choice when the most gradual approach is required for precise, controlled material placement. The 20° tip combined with the 2.0" compact length and 1/16" fine-to-medium orifice creates a uniquely low-profile precision dispensing geometry for the most demanding shallow-access applications in aerospace, defense, and critical industrial environments.

The precise 1/16" orifice diameter delivers superior material flow control — producing a consistent fine-to-medium bead profile that bridges the gap between ultra-fine and medium dispensing. The 1/16" orifice ensures smooth, uniform dispensing of adhesives, sealants, potting compounds, and other specialized materials without dripping or inconsistency. The 1/16" fine-to-medium orifice is larger than the 1/32" ultra-fine — delivering increased material throughput while maintaining precise flow control — the preferred choice for applications requiring a slightly wider, more controlled bead at the 20° shallow approach angle. For finer or wider bead profiles, the Model #420 is available in an extensive variety of orifice sizes.

At 2 inches in length, the Model #420 provides optimal compact reach — the practical standard configuration for the Model #420 series at the 20° shallowest approach angle. The 2.0" compact length combined with the 20° angled tip creates a precision dispensing geometry that excels in confined access environments requiring a gradual, low-profile approach. Whether working in flat surface joints, low-clearance assemblies, or wide-area dispensing zones, the 2.0" compact length ensures precise material placement without obstruction. For specialized projects requiring greater reach, the Model #420 is available in an extensive variety of 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 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 fine-to-medium 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.
