Tygon Tubing Type & PSI ?
 

Hello All, I got my water pump (Hagen) and heatercore (2-220) yesterday and I went here to get some Tygon tubing http://www.mcmaster.com/ only to find 6 pages of options. :confused: I plan on using 1/2" OD, 3/8" ID tubing however there seem to be a lot of choices in quality grades and PSI strength, what do you all recommend? While we're on the subject, what type of clamps do you recommend, hose, spring compression or other?

First don't worry about pressure. Usual 'watercooling' pumps don't produce much pressure.
Clamps: there are various schools. Zip ties, wire clamps, plastic 'clips', ... everything works. Choose the easiest / cheapest / best looker ...
Tygon: take 1/2" ID - this is the norm today, as most blocks made in USA have 1/2" barbs. R3603 formulation seems to be the most popular.

which wall thickness do you recommend for r3603 tygon?

oh you're in europe... do you know a place that sells tygon in small quantities?

2mm thick - i.e. 12mm-16mm for example (don't forget there are 2 walls ;) ) as it's less prone to kinks and pinches.

No :shrug: I know places where they sell it in *big* quantities (15m rolls) and at around 14€ per m.
I ordered mine together with some hardware (waterblocks..) from the USA.

I highly recommend the 1/8" thick walled Tygon R-3603. The 2mm thick walled stuff doesn't bend as well without kinking.

Thanks for help
 

Hello All, Thanks for the help everyone, I've tracked down a few sources for the tubing, looks like $2.65/ft is the best price around. I'm going to check a couple of hardware stores after work today for the clamps. I swapped the heatercore to the 2-719 as I like the I/O set up better and was only $25.00 I'm going to get some cheap tubing today and couple up the pump and heater core and let them run for a few hours to see how hot the pump gets. It supposedly can be run either inline or submersable, if it feels too hot inline I'll make a big reservoir/airtrap to mount it in.

Regardless of how hot it feels on the outside not much heat goes into the water, whereas putting the pump in water guarentees every unit of heat does...

What MDM said :D If it feels hot, then it means *that* heat aint going into water...

Looking good so far!
 

Hello All, Well I got some cheap vinyl tubing and tested the pump in line for a couple of hours. Excellent flow, almost silent - slight hum audible from 2' away, pump didn't even get warm, I'm impressed. Pump only uses 11 watts so that probally helps in keeping heat low. I've polished up the heater core, it looks pretty good, all brass and copper, I will probally put a light coat of paint on the outer edges of the fins only nothing internal that will effect heat dispersion. Heater core fin area is 6 3/4" wide X 6" tall a 2" thick, I think it should do a decent job of cooling using a single 120mm fan drawing air through it. Still working on placement of components trying to eliminate any 90 degree elbows, tubes from heater core are 45s so I don't think it will impede flow too much. I've only seen the Hagen pumps used in a couple of systems but I've talked to some people who've used these in large scale aquariums for a variety of purposes both 24/7 and intermittent for wave makers and they've all raved about their quality, power, silence and longevity. They are sold under both the Hagen and Laguna names, mines the PT-305 Utility pump 810L/214G @ 0', 11 watts, Water column 130cm/4.26' so the specs and initial testing looks promising, I'll keep you posted as I learn more.
