Custom glass tubes

What would be the danger, if any?

If a gracious mod could move this thread to the pump section I would be quite pleased famalam

Surely some companies make glass cylinders, right? And they don’t shatter on the spot, right?

Any glassblowers out there? Or would some kind of plastic material be better for custom shapes?

Youtube is a magical place think I answered my own question

This g did a few tests with large cookie jars with an empty water bottle inside, then with a partially filled water bottle. He states the larger the jar the more likely to implode, yet none of them did.

This site takes it more seriously, and suggests wrapping the cylinder with tape, keeping the pressure low, and inspecting tubes for cracks or weakness

Has a sun tea jar ever imploded on someone?

It seems if the tube is sufficiently thick walled you would be fine.

Glass is heavy, more expensive, difficult to fit a connector to, likely to shatter if you drop it, likely to cut you badly if it cracks.

Why nobody makes them.

Why take the risk.

What custom shape are you looking for? There are a lot of acrylic tube special shapes available, depending on the vendor.

Because I want to make the tube myself in a custom shape specifically for me. Glass is see through, and seems easy enough to construct.

I don’t know how to make tubes like the companies we buy from, so this would be my alternative.

It would be slightly banana and baseball bat shaped to prevent blockage of the head. And allow maximum expansion. It would have a tigertrap esque openening. It would curve upward slightly more gradually along the entire length.

Good luck with that! :)

You know that unless you are packing or have significant contact inside the tube, your cock doesn’t have a clue what the size or shape of the container is.

Thank you, correct sir I know that, but my glans specifically surely knows the size and shape of the tube when it fully packs with the force of a thousand suns.

The whole point would be giving me more space to stretch before the glans packs and blocks the vacuum

Thank you I appreciate the effort but that’s just not good enough

It needs a curve like a banana, and needs to curve upward more gradually. Especially where it expands to accommodate glans expansion.
