Serp swan neck water pipe... dia of heater tee off

[Pupp]

Just on the off chance anyone knows or has one easily to hand to measure, looking to confirm the outside diameter of the heater circuit tee off the 'S' shaped pipe on the bottom rad line - suspect it's 15 or 16mm but would like to confirm if anyone can oblige please

16mm or 5/8" old money or should be Gary

Serp original pipe off my 2000 car.
I haven't got a micrometer but I'm not bad with a tape measure

It reads 15 mm to me. But you might fit 16mm to get over the bulged part( can't think what it's called ) !








Happy to be corrected

The swaged part is about 17 mm so I can see why 16 mm is used

Gary, I think I may have a spare swan neck pipe in the garage, which your welcome to if it's any use.
