swedeguy,
I looked into this issue recently, as I happen to be collecting the materials for making my own ROP. I searched briefly in my local area for some latex tubing, but ultimately resorted to a search on the internet. You can readily obtain both latex tubing and silicone tubing from companies that supply laboratory equipment. In the USA, examples of such companies include VWR, Fisher Scientific, and Cole-Parmer. I don't know for certain if any of these companies have global operations extending to Europe, but a quick search on the internet should answer that question. If not, then how would you identify a European equivalent? I'd suggest that you conduct a search on the internet for the keywords "silicone tubing." Even easier than that, why not visit the Dow-Corning website? Dow-Corning is a manufacturer of silicone tubing. You should be able to locate the distributors for your region at their website. This is how I found the three distributors mentioned above. Of those three, I found that VWR has the lowest prices and widest selection.
A slight inconvenience is that fact that a minimum order from one of these companies is a 50 foot reel of tubing. For the size of tubing you'll probably want, the cost is about $50 US, and upwards. The best deal I found was Dow Corning "Silastic" tubing (registered tradename) from VWR. I have a reel of Silastic tubing on order from VWR, and expect delivery within a few days. The tubing that I selected is Dow-Corning part no. 515-013 (VWR no. 62999-406). The dimensions are 3/16" ID x 5/16" OD with a wall thickness of 1/16."
I'm guessing that this tubing should be suitable for both ROP designs found at Tom Hubbards Penis Workshop (http://www.tomsnewsite.Thund3rs Pl@ce.com/sperm.htm). A variety of other tubing dimensions are available, however, if you should happen to favor a different size.
In the long run, silicone tubing might be a better choice than latex. Latex rubber oxidizes and weakens over time, exactly like a rubber band. Also, some people are allergic to latex (reaction to foreign proteins imbedded in the natural plant rubber). Once the tubing arrives and I can verify that it is indeed suitable, I plan to post an announcement at [words=http://www.mattersofsize.com/join-now.html]MOS[/words] offering to provide tubing at cost plus shipping to [words=http://www.mattersofsize.com/join-now.html]MOS[/words] members in the USA, while the supply lasts. I'd be glad to send a sample on the same terms to you, but dealing with foreign currencies is troublesome. So, I'd like to offer you a free 30 cm sample - my treat. If that seems too generous, then perhaps we can work out some kind of trade: a sample of Gefilte fish in exhange the Silastic tubing, for example. Just kidding... How about a "thank you" postcard featuring a photo of a beautiful Swedish babe?
Cheers,
