Latex Tubing For Vacuum Extender

I was doing some research to find tubing and looking up the characteristics that I wanted so it would be similar but thicker than a condom. Looks like the thinnest available is .125 inches which is 50 times thicker than an average condom which is 2.5 mils. The durometer factor is between 30-60 for condoms which the rubber tubing I was looking at conforms to.

The quality of a condom is here: US Patent for Process for preparation of polyurethane condoms Patent (Patent # 4,817,593 issued April 4, 1989) - Justia Patents Search

A durometer scale is here:

Some tubing is here and eBay:

I learned I was wrong after purchasing some tubes. They were too hard. Apparently durometer scale has several types, that are Shore 00, Shore A thru D, that represent different types of plastics and hardnesses. More research is needed.

The tubes a bought were shore A durometer 35 and 50. These were not flexible enough and hard to roll up on them selves. The did not have sufficient contact with the shaft penis and pressure was lost shortly after. I’ll have to look into shore A 15-20 and shore 00 materials.

Well, you aren’t the only one who has been blindsided by such things. Any chance you can cut some up into “girth bands” so they’re not a total loss?

Think you for the idea/ reminder . I suppose I could use them as girth/clamping and hanging bands as I’ve seen people do here. I normally just use a sock, but I can get clamp burn with it.
