I assume they are because the sizes looked like US 3/4" at my GF's place.  I need to buy some fittings and things but would hate that they don't thread properly when I arrive.

Just out of interest. Why are you bringing with you ?

I'm up in the sticks & can get all, any fittings I need.

It's only a few items.  Maybe 2 or 3.  I don't know if I will bring it or buy it there.  Just not sure how much time I have there because we are flying out the same day.

The threads are actually very slightly different, but in the small sizes are close enough that they fit just fine with a good splodge of thread sealant or PTFE tape.

 

But as malt25 notes, what are you bringing that isn't available here?

Most home supply pipes will terminate with 1/2 inch fittings rather than 3/4 inch even if main lines are 3/4 inch however - suspect safer to buy locally or contract someone (such work is cheap and available anywhere).

This sentence gives me a headache.

Do you say that you will be at the GFs place only one day?

 

 

 

 

That was my first reading - but suspect he may mean only in Bangkok 1 day and then flies upcountry to her house in boondocks?

 

No they are not exactly the same, Thailand has metric sizes and US uses imperial, ergo 0.75" is in reality 19.03mm

Indeed, but 3/4" PVC has an outside diameter of 26.2mm (just over 1").

Thanks L3, evidently the bit of 3/4" that I picked up to measure is out of spec

Thanks, I saw this before I made the thread and hence the question.

Going to Samui and back.  Only in GF's home on the first day.

Which would be correct as its ID + 2xNWT 

 

26.2-19.03 = 7.17mm/2 = NWT of 3.58mm in this case, but the NWT could vary, but it still out be 19.03mm ID
