Old Fool Posted January 22, 2017 Share Posted January 22, 2017 (edited) 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. Edited January 22, 2017 by Old Fool Link to comment Share on other sites More sharing options...
malt25 Posted January 22, 2017 Share Posted January 22, 2017 Just out of interest. Why are you bringing with you ? I'm up in the sticks & can get all, any fittings I need. Link to comment Share on other sites More sharing options...

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. Link to comment Share on other sites More sharing options...
Crossy Posted January 22, 2017 Share Posted January 22, 2017 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?

lopburi3 Posted January 22, 2017 Share Posted January 22, 2017 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? Link to comment Share on other sites More sharing options...
lopburi3 Posted January 22, 2017 Share Posted January 22, 2017 That was my first reading - but suspect he may mean only in Bangkok 1 day and then flies upcountry to her house in boondocks? Link to comment Share on other sites More sharing options...
Savilesghost Posted January 22, 2017 Share Posted January 22, 2017 No they are not exactly the same, Thailand has metric sizes and US uses imperial, ergo 0.75" is in reality 19.03mm Link to comment Share on other sites More sharing options...

Crossy Posted January 22, 2017 Share Posted January 22, 2017 Thanks L3, evidently the bit of 3/4" that I picked up to measure is out of spec Link to comment Share on other sites More sharing options...

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 Link to comment Share on other sites More sharing options...
