Im using the 7/16 house and am pleased that it's less bulky, no loss of performance, no need for hose clamps, and is more flexible.

Smaller than the 3/4" OD stuff, so looks neater. Easier to route. Not as heavy. No noticable loss in flow-rates (and therefore performance).

The big win comes in the ease of routing though. While no more flexible in terms of kink resistance than the Clearflex or Tygon 1/2" w/ 1/8" walls, it is a heck of a lot easier to bend. Probably takes 1/3rd the effort to bend the 7/16" w/ 3/32" walled stuff to the same radius.

Just as kink resistant as the 1/2" ID w/ 1/8" walled stuff, so can turn the same corners, but with a lot less effort.

Definitely something for the enthusiast to consider if they want all the low-flow resistance benefits of 1/2" tubing (when using less than about 2m of tubing), but want tubing that's not as fat and easier to route.

Using more than 2m of it is not going to suddenly hurt you or anything, it's just that this is the "cross-over" point where the 7/16" ID stuff will gradually start to offer more resistance than the 1/2" ID stuff, once barb interfaces are taken into account.

Sounds good to me!

thanks for the info.

Danke for the info Cathar and everyone else!

As much as I'd love to use this, my 5/8" inlet/outlet on my heatercore will probably cause me great trouble. I suppose I could sweat some barbs or pipe nipples or something onto it.

Bringing back a dead thread but anyone in for a group buy?

got some in today seems verflexible should have the blocks tomarrow :cool: .

mcmaster has some that can be obtained at your perferred length, It's not tygon but very flexible.

I actually had to measure it to make sure mcmaster did'nt mess my order up because this stuff looked so whimpy. For a second I thought I had ordered tubing for a koolance ;) :D . No really, it is great stuff.

i had no problems what-so-ever getting this stuff to bend some incredibly tight turns without kinking.. ?
