Lightweight Ducting

[skippydiesel]

I need thin walled, heat resistant, light weight, flexible,  about 30 mm (1.5") ID, ducting

 

I have wire reinforced SCAT tubing. The wire is in the way of what I want to do.

 

I have removed the wire but it leaves the "fabric" damaged - it does the job "at a pinch".

 

Would much prefer something similar to SCAT, without the wire.

 

Anyone know of such a product and where I can get it from????

 

All constructive suggestions welcome.😈

I used this to replace the demister ducting on one of my classic cars.

Thanks T510.

 

Unfortunatly my application has almost continual small (occasionally larger movement) .

 

I would be concerned that the aluminium would fatigue quite quickly.

 

Thanks again😈

Thanks Onetrack,

 

A quick brows would suggest that the ducting is either wire reinforced (too stiff) , to large an ID or has insufficient heat range for safety. 

 

Thanks for trying

If such exists- SCAT, without the wire would be perfect. 

 

Something along the style of lightweight lay flat hose. 😈

Skippy - What level of "heat resistance" are you actually seeking? (precise temperature range). I fail to understand how you think you can acquire "thin, flexible, heat-resistant" ducting, without it having some kind of internal support.

 

You either have thin ducting supported internally by wire or PVC ribbing, or you have thicker wall, unsupported ducting. A thin wall is not going to support itself, that's why layflat hose lays flat.

Ha ha!

 

The hose/duct need not be self "supported" because the gap between the carby  & airbox is only about 10mm.

Due to the short distance, the wire ribbing of the SCAT gets in the way & restricts some of the relative movement that needs to happen.

 

Temperature Range - From ambient Australian east coast winter, say a rare 0C,  to summer, under cowl , post engine shut down 80C. In operation the undercowl temperature is a consistent +10C above ambient. The duct will be supplying outside air, from the air box to the carby(s), so there is the potential for -C (?) temperatures at altitude.😈
