Empty Fillable Plastic Caulk Tube 300 ml. Also Know as 10 oz. 11 oz. Standard Size and Pint Size Caulk Tube (8)

This worked really well for me. I had a 5 gallon pail of Sasho caulking.I used to use a very large caulk gun that would suck the caulk into the very large tube. I don’t have that gun anymore.Once I figured out how to load this tube, by using a spoon and a dowel, it worked just like any off the shelf 10 inch caulk tube.Be aware that The insert at the bottom of the tube will seem very stiff when you push it in but it seals the bottom of the tube beautifully when using the gun.

These worked okay if this is what you needed. I only used 1 and gave away the rest.

It works all right with tight plug in the back. I found that epoxy grout is too heavy to come out.So half hour later, I cut the tube and pulled half remained grout out.It would be much more useful for creamier material such as regular grout.So I am keeping rest of 4 tubes for future projects.

Used to inject fiberglass resin wirh filler into a drilled hole

these are handy for many jobs around the shop. good quality & sometimes reusable.

A pain in the but to fill , once past works great!

Good stuff

Going to use this item for grout application.
