The Model #440 is a specialty funnel nozzle — fundamentally different from straight round-orifice and ribbon nozzles. The funnel design features an approximately 2.0" wide orifice — creating a wide, tapered funnel profile specifically engineered for the application of sealant over large aircraft fasteners. The 2.0" funnel orifice seats directly over large fastener heads — delivering consistent, uniform sealant coverage across the entire fastener surface in a single dispensing operation. No straight-orifice nozzle can replicate the wide, tapered funnel coverage geometry of the Model #440.

The Model #440 measures 3-1/8" in total length — a compact, efficient design optimized for aerospace fastener sealant application in maintenance and manufacturing environments. The 3-1/8" total length provides the ideal nozzle body geometry — allowing the funnel to transition smoothly from the 1/4" NPT cartridge connection to the 2.0" wide funnel orifice. The compact length ensures easy access and maneuverability in aerospace maintenance environments — delivering professional results every time with consistent coverage and minimal waste.

The Model #440 is specifically engineered for the application of sealant over large aircraft fasteners — the most critical sealing application in aerospace maintenance and manufacturing. The 2.0" funnel orifice is sized to seat directly over large aircraft fastener heads — delivering consistent, complete sealant coverage in a single dispensing operation. The funnel geometry ensures uniform sealant flow from cartridge through nozzle body to the 2.0" wide funnel orifice — creating a professional, consistent sealant cap over each fastener for demanding aerospace applications.

The funnel design facilitates precise material flow control — minimizing waste while maximizing efficiency in aerospace maintenance and manufacturing processes. The 2.0" funnel orifice delivers the exact volume of sealant required to cap each large aircraft fastener — eliminating over-application and material waste. The consistent, repeatable funnel geometry ensures professional results every time — delivering uniform sealant coverage across every fastener in your production run or maintenance operation. The disposable design eliminates cleaning requirements — streamlining your aerospace workflow.

The Model #440 is designed to be used in conjunction with either pneumatic or manual dispensing guns — providing flexibility in your operational workflow. Use with a pneumatic dispensing gun for production environments requiring consistent pressure and output for high-volume aircraft fastener sealing operations, or with a manual dispensing gun for maintenance operations needing direct operator control. For pneumatic setups, a pneumatic hose ensures reliable air supply — completing a full and efficient aerospace sealant dispensing system.

The Model #440 represents the pinnacle of precision dispensing technology for aerospace applications — meticulously molded to exacting specifications. The precision molding process ensures consistent wall thickness, dimensional accuracy, and uniform 2.0" funnel orifice geometry across every unit — delivering repeatable, reliable wide-coverage funnel output in every aerospace fastener sealing operation. The standard 1/4" NPT male thread provides seamless compatibility with the complete range of Semco® disposable cartridges — 1 oz through 1/10 gallon.
