Versatility at odd angles and in confined spaces — no step obstruction for unrestricted access

Wide 1/2" orifice — controlled material flow for broader fillet bead coverage in critical dispensing applications

Optimal reach — access to joints, sealing areas, and fillet application zones with precision control

Unique center depression — shaped fillet bead profile for precision contoured material placement

Seamless connection to all Semco® cartridges & Semkit — 1 oz through 1/10 gallon

The Model #429 features no built-in step, offering versatility when used at odd angles and in confined spaces where conventional stepped nozzles cannot perform. This design advantage makes the #429 the preferred choice for complex assemblies, precision fillet applications, and critical dispensing operations requiring controlled material placement in restricted access areas. The 1/8" middle dip geometry further enhances bead profile precision — delivering consistent, reliable dispensing performance in your most demanding applications.

The 1/8" middle dip is a unique orifice geometry feature that creates a shaped fillet bead profile with a controlled center depression — engineered for applications requiring a precisely contoured fillet bead across the full 1/2" orifice width. This distinctive dispensing geometry delivers consistent material distribution with a defined center profile for critical sealing, bonding, and fillet applications in aerospace, defense, and industrial environments where standard flat-profile nozzles cannot achieve the required bead geometry.

The 1/16" x 1/2" orifice delivers controlled material flow with a wider 1/2" bead coverage — engineered for precision fillet bead geometry in critical dispensing applications. The wider orifice profile produces a broader fillet bead that covers larger joint interfaces, ensuring complete coverage and adhesion across wider sealing surfaces. Combined with the 1/8" middle dip, the orifice geometry delivers a uniquely shaped bead profile for demanding fillet applications.

Precision-molded with a 1/4" NPT male thread — seamlessly connects to the complete range of Semco® disposable cartridges across 1, 2.5, 6, 8, 12, 20, 32 oz. and 1/10 gallon sizes. This universal compatibility ensures the Model #429 integrates into your existing Semco® dispensing system without additional adapters or fittings. Compatible with both pneumatic and manual dispensing guns — delivering consistent, reliable dispensing performance across all gun types and operating environments.

The 4-inch length provides optimal reach for standard fillet applications — accessing joints, sealing areas, and fillet application zones with precision control. Combined with the 1/16" x 1/2" orifice and 1/8" middle dip geometry, the 4.0" length delivers the reach and bead profile precision demanded by critical aerospace and industrial dispensing operations. For applications requiring different reach distances, the Semco® fillet nozzle system is available in multiple lengths to match your specific access requirements.

Compatible 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.
