Zalman ZM-WB2 1/2" ID?

Does anyone have a Zalman ZM-WB2 and have a 1/2" ID+3/4"OD tubing hooked up to it? I'm wondering if the compression fittings will work with this kind of tubing. Or if I would have to get different fittings.
thanks

you would have to add 1/2" ID tube compression fittings to it to get it to work. Compression fittings only work with their specified tubing.

It would probably be hard to find compression fittings that accept 1/2" ID tubing and that also would fit the threading of the block. The small thread diameter, since it's made for 3/8" tube, would probably negate any gain you'd get from 1/2" ID fittings.
