Metric pipe sizes???
Metric pipe sizes???
(OP)
Our company Mostly does plastic injection molds for US, which means that they are all standard (imperial) sizes, and we never had a chance to do any metric stuff.
This is a first time that im designing a mould in Metric. So my question is. Is there such thing as metric water lines (pipe thread sizes) (forgive me for a retarded question).
I remember once (when i was on the shop floor) pluging water lines with STRAIGHT pipeplugs, and i remember job being metric. But averybody up here is telling me there is no metric pipe sizes.

ISO adopted BSP(tapered) and BSPP(parallel) pipe threads.
Study your Swagelok catalog; they have adapters for most possible situations.

On most sizes I have used, they start, but bind after 2 or 3 turns and leak. In an emergency you can generally make them work with plenty of thread tape and thread sealing compound, but it is not pretty.

As Pat said, they all fit (Thread angle difference), just takes more grunt to seal!
