Product description

This spray gun had some nice features to adjust flow with the brass thumb screw at one the end.
The 3 different metal “straw” ends attached securely and allowed easy access to smaller openings that you want to insulate and seal.
The trigger motion was smooth and the threads on the end allowed my cans of foam to attach and pierce correctly when threaded on and tightened.

Well worth it
Worked flawlessly. A can of gun cleaner is not only recommended but necessary IMO.

Good foam gun
It’s a good foam gun for the money . Works better than a $70 good stuff gun. With extended nozzles that are super useful. Would buy again

Doesn’t feel very long living
This is a really low end applicator. It is made of metal at least, but I’ve had a few different ones of these and this is by far the cheapest one I have had. It does work but the overall feel makes it seem as if it’s going to fall apart at any second, I wouldn’t but this again likely

Pretty well made gun and long nozzles are very helpful but need a complete instruction sheet.
This spray gun had some nice features to adjust flow with the brass thumb screw at one the end. The 3 different metal “straw” ends attached securely and allowed easy access to smaller openings that you want to insulate and seal. The trigger motion was smooth and the threads on the end allowed my cans of foam to attach and pierce correctly when threaded on and tightened. My reason for docking one star is for lack of good complete directions. For example, there is a bag included with two tiny clear plastic nozzles and two O-rings, but no explanation on how they work or what they are for? I’ve used spray form guns previously, so somewhat familiar with their use, required solvent cleaning process etc. but feel a bit lost without a complete instruction sheet.

This review is for the GDUSMCN Three sizes of stainless steel spray gun extension nozzles, 2 each, with 5 small-diameter plastic nozzles included.For the price, this gun nozzle and extenders do a fairly decent job of helping to apply expansion foam or adhesive foam into some pretty difficult to reach spots. The gun itself is reasonable quality, though not as good as some better known brands. It has an extra ‘feature’ which is a ball valve allowing the user to stop the flow of foam into the gun barrel. Although this seems like a good idea, and perhaps it is, other guns rely on the trigger mechanism and spring to stop the flow, so I’m not sure if this extra valve/stop is really necessary.the nozle extensions themselves are composed of three threaded long tubes (one of them has a bend for additional reach options) and appear to be made of aluminum and are fairly sturdy.The trigger is adjustable, by turning a threaded knob at the end of the gun, allowing the user to define the rate at which product is dispensed. The handle is hollow, but fairly sturdy and comfortable to use.The package also comes with a set of three tiny plastic nozzles that appear o be pressure fit. They don’t fit on the end of the gun, like it appears in the sellers images, and can only be pressure fit on the end of a nozzle, but i expect this thing would come flying out when it came time to dispensing as it is so fine and pretty much useless, even for detailed application.Overall, a solid 4 stars for quality and function, but I’ve raised it to 5 because of the value pricing of $37 which is pretty good for what you get.

Really impressive foam gun, especially for the price.I picked this up primarily for the longer nozzle extensions to get into harder to reach crevices that my “Good Stuff” gun can never make, but didn’t expect the gun to be such good quality.It’s solid steel, quite heavy, and generally just a very good gun. The mechanisms are all smooth (the toggle is smooth and fully opens/closes easily, the trigger feels good and is really easy to pump, and the canister receiver is solidly attached to the gun and is easy to thread on/off.)The nozzles thread onto the tip of the gun easily, and are also very solid and rigid. As with working with foam, you just need to be careful with how you leave the tips when you’re finished with them, as they are difficult to clean if you don’t do it immediately.Overall this gun is really impressive, and offers excellent value. It feels like the same quality (or even better) than the other mainline foam guns out there, but for half the price. The value of this gun is really good, especially with the additional extension heads that can help get into those tougher areas.
