early heater valve to heater hose

[rmoore007ri]

Until about April 1971 the short hose from heater valve to heater was 14 mm id diameter at one end and 18 mm id at the other end. 

It now seems to be made out of the rare mineral unobtanium. Any pointers to the correct hose would be much appreciated.

Buy another one of the adaptor type hoses from Blunt (the long one) and cut it. If I build another early car I would make everything 18 mm to prevent headaches.  The heat in my 69 is really good - even with the small heater valve and core. Wonder why BMW changed it?

They had trouble with the small brass- on- brass valve.

I think the original BMW coolant spec had lube in it.

 

Plus, there's Scavahoovia-

VW gave up and fitted a gas burning heater

to T3's going up there.

The heater core in my Volvo 122 is bigger than the radiator...

 

and so on...

This sounded familiar to me - I just replaced something similar on my '72 240Z.  Nissan part number 14054-E3001 is just over 18mm at one end and just under 13mm at the other.  Might just work and is readily available for around $4.

I downgraded from 73 heater valve to 72 and used this silicon hose as converter. Perfect match.
