do the tubes contain a seal over the opening which must be removed prior to use?

No they do not have a seal over the opening. I have been buying Biofreeze for years without a seal.

not sure of what you are asking. the seal is one peace their is'n any half and half when you take the pump apart you will see what i'm saying. very easy to do, and this will help alot.

Not that I remember. I had to send mine back because the seal comes off way to easy and it leaked. It also doesn't hold temp for long

don't know. I used mine right away but they appeared to be wrapped up tightly and everything sealed.

Well, the very bottom of the tube has a threaded bushing that's used to adjust the "travel"(the distance the shock absorber moves up/down) so in a sense it is sealed, as it is not open ended. Hope this explanation helps. Note: Some people have reported that the post may have a tendency to swivel left to right while riding (possibly caused by loosening the tension for more travel on the shock absorber).

I have not used it, but I believe the answer is no. It appears to be a flat, fairly large, waterproofed seal. I believe you simply place it over the wound, especially a sucking chest wound, and seal the area. Be sure to look for both entry and exit wounds.

Yes, they have a snug seal. We have a dozen of these now and have never had that problem. Ours are stocked with rice, lentils ect.

Mine did have the seal. I think if I were you, I'd request another bottle. To be honest, I can't remember if there was an inner seal or shrink wrap around the bottle top. I do know whichever type it was, the seal was intact.

it has a rubber o ring/seal from what i remember, you shouldn't have to buy anything extra other than hoses if needed.

Yes, there is a rubber seal around the main screw on part. I know some people put an airlock in the spout hole for fermenting foods. Agree the spout hole isn't ideal.

I just received mine and it looks like the box had already been open and there was no kind of seal on the tube!

No need to remove seal. It can take a lot if heat. Use vents to control air flow to coals.

Unfortunately I do not remember, as I used the existing tube already in place. However they are available at the major Box Stores for around $10-15.

Yes, You just have to keep the liquid away from the vacuum tube. A good idea it to freeze the product then vacuum sealing it.

It does have a seal , however I don't think it is completely airtight. We do use ours for coffee but we use the coffee at a quick rate so it is not a factor for us.

Not necessary to seal at all. I used this as a dining fly during a down pour in the White Mountains...kept dry...ready to perform right out of the box.

No, they are solid with no removeable parts. They do not have a seal. I love these caps!!
