Semco® Sealant Dispensing Tools

You can see the contrast on the windshield of before and after. I run twice to get the impacts.

Short and simple to use. Nice for touch up

Love this in comparison to the other model without the handle.

Easy to order online and fast delivery.

Feels sturdy and holds the 8oz cartridges securely with the 850 gun. Simple to set up and fits as expected. A bit pricier than I hoped, but the quality makes it worth it.

Comfortable grip and good control over the bead for sealant work. The action is smooth and it fits 6oz cartridges just as advertised. A bit heavier than I expected, but the build feels solid and it’s easy to clean after use.

Does exactly what it’s supposed to do and fits our existing SEMCO setup without any issues. The 5/32" size is spot on for standard rivet holes and helps keep sealant application clean and consistent. Only thing I’d like to see is multi-pack pricing, but for performance and quality, no complaints at all.

Picked up an extra 820 Sembend nozzle so I’m never stuck waiting on stock. The flexible tip makes it easy to hit tight spots with good control. Only downside is I wish they offered multi-packs at a better price, but performance-wise it’s been reliable and worth having a backup.

Flexible tip makes it easy to reach awkward areas. Dispenses in a fine line without a mess. Would be perfect if it came with a cap, but still great for precision work.

Needed this spatula for sealant work and it did exactly what I needed. The dual ends are useful and the plastic feels sturdy enough for repeated use. Shipping was quick and the red color makes it easy to spot in the toolbox. Not much else to say—it works as advertised.

Solid extension nozzle for precise dispensing. Threads sealed up nicely with no leaks, and the 1/4" NPT fit our setup without any drama. Only thing I’d change is offering them in multi-packs at a slight discount, but for a single unit the quality is clear. Overall, exactly what we needed for clean, controlled application.

Picked up an extra funnel nozzle so I’m not stuck waiting on backorders. Works well for directing sealant exactly where I need it, and cleanup is easy since it’s disposable. I do wish they were a bit easier to find in stock, but the quality is solid and consistent so I’ll keep buying them.

I use these seal caps regularly to protect my cartridges in storage and they work exactly as advertised. The red color makes them easy to spot in a busy shop, and the fit on the threaded ends is nice and secure. My only complaint is that for a simple cap, the cost feels a little high when you need several of them, and they’re not always in stock when I want to reorder. Still, very reliable product and a clean, easy-to-use website.

Product is great. My only concern is the shipping time is longer than usual!

The 7-inch Semco spatulas gave me good control for smoothing fillets and cleaning excess sealant in tighter spots. The different shapes in the kit made it easier to switch between wider areas and detail work. Only thing I’d change is slightly stiffer blades for heavier material, but overall they performed very well for my sealant applications.
