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

Controlled material flow — precision fillet bead geometry for critical dispensing applications

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

Wider tip angle — broader angular access and increased clearance at joint entry points vs. #426 & #428's 1/16" tip

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

The Model #427 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 #427 the preferred choice for complex assemblies, wider joint geometries, and precision fillet applications requiring controlled material placement in restricted access areas. The 1/8" angled tip provides broader angular access and increased clearance at joint entry points — delivering consistent, reliable dispensing performance in your most demanding applications.

The 1/8" angled tip delivers broader angular access and increased clearance at joint entry points compared to the 1/16" tip of Models #426 and #428 — making the #427 the preferred choice when wider angular clearance is required at confined space openings, joint entry points, or assembly interfaces. Shares the same broader tip angle as Model #425 — select the #427 or #425 based on your specific system configuration. For applications requiring tighter angular access in narrower confined spaces, Models #426 and #428 with 1/16" tip are also available.

The 1/8" x 3/8" orifice delivers controlled material flow — engineered for precision fillet bead geometry in critical dispensing applications. The rectangular orifice profile produces a consistent, shaped fillet bead that conforms to joint geometries, ensuring complete coverage and adhesion at sealing interfaces. For applications requiring different flow rates or bead profiles, the Semco® fillet nozzle system is available in multiple orifice sizes to perfectly match your specific application requirements.

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 #427 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 1/8" angled tip, the 4.0" length delivers the reach and broader angular flexibility 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.
