Water Cooling hoses

Need to find some good 1/2" hosing for new water cooling setup, tried looking on ebay for short period of time didnt really see anything, anyone know where and what to get ? also is there any tubing that disperse's heat as the water travels through it? every little bit helps i suppose
Thanks guys

1)Tygon is best but expensive.

2)Clearflex is almost as good but 1/2 the price.

3)Copper tubing will disperse a not insignificant amount of heat. Plus you need a tube bender.

Clearflex and Tygon are commonly used. Vinyl from your local hardware store would work aswell. Most watercooling vendors carry tubing. Mcmaster is also a popular place to get clearflex (may be an equivilent brand now?). Find page 85 and match this line:

1/2" 3/4" 1/8" 3" 30 10,25,50,100 5231K237 .65

As for tubing dispersing heat you would need something like copper tubing with fins...
