Thread: Solving the 16mm to 10mm hose issue

16mm is 5/8, 10mm is 3/8. You'll get a reducing nipple in brass from pirtek etc for this.

I suspect Its that joint between the two hoses on mine that's drawing air not my system - will have a look in pirtek for that reducing piece...

my repco store has brass fittings

Thanks to all who replied - didn't even think about hydraulic fittings for the water pipe. Chased up with my brother in law, who runs a hydraulic business. He supplied a brass 10mm barb with a male thread and a brass 16mm barb with corresponding female thread, as this is what his supplier could provide. Much thanks to him for the quick supply of these goodies. Some loctite pipe sealant on the thread section and the adaptor is ready for installation. Just need to ensure that the weight of the adaptor is supported by something other than the radiator header nipple, so that there isn't too much strain on the plastic.

It appears that IFS (see online catalogue at Welcome To Industrial Fittings Sales) also sells a brass barb adaptor 07P07R 1006 (3/8" to 5/8") (P7R reducing hose joiner), which would be a bit lighter than the config that I have.

There is also a 16mm to 10mm brass adaptor available on ebay.co.uk for about 7 pounds, including freight (royal mail). Venair Silicone Hose World (16mm-10mm-BRASS-BARBED-Fuel-Hose-Joiner).

Brian, no problems if you have a lathe mate!!!! But, it's true that you can quickly machine one up (just spend $$$$$ on the lathe, or $10 to get a fitting).

If you are serious about maintaining/modifying/restoring old vehicles you need a lathe at least 40" between centres preferably more, a decent MT3 pedestal drill, a small high speed drill press, some sort of heating and cutting gear, welding equipment, a decent hydraulic press, several bench grinders and linishers as a minimum. Add the usual hand, power, air tools and you are on your way. A universal milling machine with motorised overarm and vertical head is nice to have but not essential.

First of all apologies- you were answering the question I posed; I was thinking of off the shelf, rather than hand crafted. When lathing this , do you do the hole first or last? I have limited lathe experience. By the sound of things, you have a reasonable workshop- the bloke down the road with 3 Model Ts doesn't have as much as you describe!! And he has what I call old cars.
