PPG® Semco® 700001 Model 640 30° Bend, 6" Long Nozzle x 1/8" Orif.

Not all sealing jobs are straightforward. When you need to get into tight, oftentimes awkward spaces, you need a PPG® Semco® 700001 Model 640 Nozzle from SkyGeek. This specialty nozzle features a 30-degree bend and a six-inch length, tapering down to an 1/8” orifice. That means it gets in where you need it to go and delivers sealant to those tight, tricky spaces that are otherwise impossible to reach. The nozzle is compatible with most Semco® cartridges.

Whether you're crawling into a wing root or are trying to seal a complex assembly with a lot of awkward angles, this precision nozzle keeps the flow smooth and the frustration low. It’s built tough enough to handle high-viscosity materials without bending, clogging or testing your patience, but it’s good for materials that flow too. The angled design gives you better control while maintaining a clear line of sight — a small detail that makes a big difference when you're elbow deep in your aircraft and are trying to lay the perfect bead.

This plastic dispensing nozzle works with most Semco® cartridges and dispensing guns like a dream, clicking into place and getting the job done without a fuss. It’s a simple tool, but an important addition to any aviator’s toolbox. Like most things in aviation, this little nozzle makes a big impact when used right.

Trying to force a straight nozzle into a curved space is a recipe for disaster — or at least a lot of frustration — but with the PPG® Semco® 700001 Model 640 Nozzle from SkyGeek, you can navigate all kinds of angles to smooth out seals and make your sealant work look professional on the first try.
