content: Hi!I'm trying to modify my Aoyue SMD workstation, and add hose spliter and extension so I can use both SMD pickup tool and fume extractor. Does anyone knows where I can find similar hose like they use? It's super flexible, I'm guessing 6mm ID 8mm OD and wall thickness about 2 mm... So far all I can find are very stiff hoses... Preferably in USA or China

content: Silicone Rubber tubing from McMaster-Carr perhaps? (This /might/ get you to the page; if not go to McMaster.com and search on 'tubing' to find possible solutions.):http://www.mcmaster.com/#standard-plastic-and-rubber-tubing/=zr449j-Pat

content: 6mm ID sounds quite large..I'd try something like this:http://www.amainhobbies.com/rc-cars-trucks/du-bro-extra-large-silicone-fuel-tubing-blue-762cm-dub897/p276814mm ID, super flexible, and very, very cheap compared to the alternatives.If you have a well-stocked hobby-shop in your area, they can probably give you an inch or two for free for you to test with.You're looking for "Extra large" or "High flow" fuel line/tubing.

content: Since the OP is in the US,www.usplastic.comis a great company that stocks a LOT of different plastics/tubing etc etc.The shipping is the costly part...cheers,george.

content: Wow, thank you guys! Fantastic info! I even found tubing clamps on USPlastics! I'll probalby order tubing from McMaster, since it's very descriptiveP.S. It seems what I was looking for is "latex rubber" type tubing and not siliconeThat's the most flexible kind I'm guessing.

content: Sorry but it likely will not work for fume extraction. Why? I'm assuming that the vacuum pump used for pickup and the tubing will not be sufficiently sized/rated to handle enough CFM's to get the fume extraction part done.

content: It works just fine for fume extraction :-) Built in pump too strong for smd vacuum tho

content: Yeah, McMaster Carr has just about anything you could want hardware and raw material-wise. I've been slowly building up my screw stash as I place orders there - I'd much prefer to pay $5 or $6 for a box of a hundred screws than drive to Home Depot and pay $1.25 for 7 of them. And it always seems to be some weird number, so you almost invariably need two packages of them and are left with some odd number of extras.-Pat
