Cooling pipe work - Again!

Im currently in the process of moving a radiator to the front of the van and found this stuff - http://www.pipestock.com/pph/pipe/10-bar/

Seems that it works upto 100degC which should be safe enough to use at normal engine temps and alot cheaper than hoses/copper pipe. It also has the option of diff shaped joiners to hopefully get round the steering rack and stuff.

My plan was to use this for the long sections and use hose clips to attach the flexi hoses to the pipe. I thought about using some high temp glue to help seal/hold the hose onto the pipework so it dosent slip off?

Anyone else given something like this a try?

You'll need something that can handle temps higher than 100c.

Thats only a few degrees above running temp, most cars bring the fans on around 96-98c so temps over 100c are perfectly normal.
The pressure may split that stuff.

You need atleast 120c compatible materials, thats the average boil temp for most cooling systems

WHS ^^^^

100°C is too low a working temp, 8°C above full 'stat opening. Your water will hit approx 120°C before boiling (16 ish psi)

Just use Pirtek/Steel/Copper etc all tried and proven

Ah I never thought about the temp of the water coming directly from the engine once the thermostat opens.

The main reason behind using the plastic pipe was the price but guess its best to do a job right first time rather than twice. Now thinking of using aluminium pipe. Dont fancy the pipe bursting when the engine temp gets up while climbing a big hill...

Thanks for your advice! Grin
