Cornucopia Brands Empty Plastic Caulk Tubes, 11-Ounce (4-Pack); Refillable Sealant Caulking Tubes

Good quality. Pretty much as described except I don't see how you can reuse them unless you have an air compressor to blow the piston back out. If you have a compressor, a football inflator or similar nozzle does this easily. I reused one nearly 20 times with no loss of performance like excessive leaking or sticking.

It is true that these can only be used once, but if your like me, thats more than enough!I am an electrician and in an apartment complex we wired, we had to install firebrick in every upper and lower penetration we made. So we got a huge bucket of fire block ( not the tubes because they're more expensive) and after a week of fire blocking with a putty knife, I had to find a faster way to install the fire block. So I bought a few of these tubes and now we use them to fill up with fire block and do it 5x faster!Its worth the money. I would consider these disposable tubes since they are good for one use only.

Ordered these for grouting back splash tiles with a lot of inclusions so I wouldn't lose the rustic look by grouting with a float. Tubes were easy to fill, worked great on the first use but couldn't remove the plunger/cup thingy (technical term.. . :) ) to refill the tube and ended up destroying it in the process. But they were inexpensive enough so I didn't feel too bad about using all 4. I would buy them again.

Great concept but needs to be manufactured differently. I used these tubes to put grout in my travertine tile as I didn’t want the grout to fill the naturally occurring porous holes in the tile. They worked pretty good but the grout would tend to harden in the second tube I made up. I had to mix enough grout to accommodate only one tube at a time. My biggest issue with the tubes was that it is really difficult to remove the plunger once the tube was empty. I devised a way to remove the plunger (see pictures below) that worked pretty good. If the manufacturer would have made the plunger out of metal it could have been removed easily by pushing a screwdriver through the tip. Using a screwdriver, the way they’re constructed only puts a hole in the plunger.

The media could not be loaded. I absolutely loved the plastic refillable caulking tubes. I had a 16 x 18 lava stone deck that I needed to grout and all of the crevices between the lava stones were of various sizes and depths. These tubes were great for getting the grout deep down between the stones without getting excess grout on the lava stone or in the little holes on the stone. They saved a tremendous amount of time and greatly reduce the cleanup.

The tubes are fine enough, but to say they are reusable is, for the most part, a fallacy. To "reuse" these you must have an air compressor to shoot the cap out of the back. It is all fine and good if this is the case, but, this should be mentioned by the seller. You shouldn't have to look down in to the reviews from others to find this out after the fact.Boo on you seller!

I used them to inject grout to fill voids with only limited openings. After I filled the tubes, I wiped the ends to make the plastic inserts easier put in place. They did the job. They were single use, but that is normal for this type of applicator. I see some ideas to reuse them in the comments, but that was not my expectation.

These tubes have made laying grout between tiles MUCH faster and easier. If using sanded grout, I recommend mixing it a little thinner than you normally would so that it flows easily out of the spout. The spout comes closed, so must be cut to open it. The size of the hole needs to be made with the viscosity and texture of the contents in mind. I heartily recommend these tubes.
