Can I use metric instead of inch?


Hi
I am about to buy a stock of adapter for water purifier (faucet divertor. please see attached picture), some chinese factories only work with metric system and I wonder if I can use them. my questions are:
1. Some answers I got is that the most common tap would be 55/64(at the connection point to an aerator). Do you agree that this would be the most widely used?
2. Since it is 22mm metric vs. 21.83mm (55/64inch x 25.4mm), and since factories that work with the US make only metric, can I assume that 22mm is also used in the US (no damage and no leaking?).
Thank You

The threads must match not just the diameter. I have never seen a metric thread that would work properly on an imperial thread.

Very close is not "good enough" when working with plumbing.


Leaks will occur, and then unhappy results.

'Close' only counts in horseshoes, grenades and slow dancing.

Re: Can I use metric instead of inch?


OK I got the message. no metric is welcome at the US

And what would be the most common?
at the attachment you can see 55/64F, 3/4F an also they say that there is an option for bathroom M28-1 (what is the parallel in the US?)

so, which one of this three should I go for?

I wouldn't go that far. There are plenty of tools, machinery, equipment, parts etc made in the US to metric standards.

Re: Can I use metric instead of inch?


Another small detail your stuff must hold a lead free certification. Because it is used for drinking. ASME A112.18.1/CSA B 125.1. ,,NSF 61, Section 9,,
It will need to be tested to meet or exceed the above standards.
