Shallow approach angle — accurate placement at low-profile joint interfaces, recessed cavities, and close parallel access zones

Precision bead — controlled material flow without dripping or inconsistency for critical dispensing applications

Extended compact reach — greater access depth than 1.0" nozzles while maintaining close-range precision placement control

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

The 30° angled tip enables accurate material placement and consistent bead application — even in hard-to-reach areas where straight nozzles cannot access effectively. The shallow 30° geometry provides a lower-profile approach angle — ideal for applications requiring minimal tip deflection, close parallel access, and precise dispensing at shallow angled joint interfaces, recessed cavities, and confined assembly areas. The shallower angle vs. steeper 45° nozzles delivers smooth, uniform material flow without dripping or inconsistency for adhesives, sealants, potting compounds, and other specialized materials.

The 1/16" orifice delivers precision-controlled material flow — engineered for applications requiring a consistent, controlled-diameter bead. The precision orifice ensures smooth, uniform dispensing without dripping or inconsistency — the preferred choice for precision adhesive, sealant, and potting compound applications in aerospace, defense, and industrial environments where exact bead geometry and controlled flow rate are critical to application success. For applications requiring finer output, the Semco® nozzle system is available in additional orifice sizes.

The 2-inch length provides extended compact reach — offering greater access depth than shorter 1.0" nozzles while maintaining close-range precision placement control. Ideal for deeper access zones, recessed joint interfaces, and confined assembly environments where additional reach is required beyond what compact 1.0" nozzles provide. Combined with the 30° angled tip and 1/16" orifice, the 2.0" length delivers the reach and shallow-angle precision demanded by critical aerospace and industrial dispensing operations. For applications requiring greater or lesser reach, the Semco® nozzle system is available in multiple lengths.

The Model #420 operates 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 hose assemblies for reliable pressure delivery — creating a complete, optimized Semco® dispensing system for consistent, reliable performance in your most demanding applications.

Designed for superior material flow control across a wide range of dispensing materials — including adhesives, sealants, potting compounds, and other specialized materials. The 1/16" orifice and 30° angled geometry ensure smooth, uniform dispensing regardless of material type — delivering consistent bead application without dripping or inconsistency. Semco® offers the Model #420 in various lengths and orifice sizes to accommodate different material viscosities and specific application requirements.

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.
