miketu Posted December 3, 2015 Share Posted December 3, 2015 Hi, I want to buy a shower head with filter in the U.S. for my condo in Thailand. Will the threads on the U.S. made shower head be compatible with the Thai shower pipe fitting? If not does anyone know what the common thread size (metric?) for bathroom shower pipe fittings is in Thailand so I can bring over an adapter? Thanks, Mike Link to comment Share on other sites More sharing options...
Crossy Posted December 3, 2015 Share Posted December 3, 2015 Whilst not exactly the same (thread angle is different) small sizes (like your shower stuff) should fit just fine. Moving to DIY. Link to comment Share on other sites More sharing options...
kannot Posted December 3, 2015 Share Posted December 3, 2015 UK 15mm pipe fittings are the same also as Thai half inch although Thai threads are sloppy poorly manufactured needing tons of ptfe tape Link to comment Share on other sites More sharing options...
miketu Posted December 3, 2015 Author Share Posted December 3, 2015 UK 15mm pipe fittings are the same also as Thai half inch although Thai threads are sloppy poorly manufactured needing tons of ptfe tape Thanks. So Thai pipe threads, for bathroom showers, are measured in inches and not mm? If that's the case then a shower head from the U.S. with SAE inch measurement threads should fit my Thai bathroom shower if the pipe diameters are the same size?

TerminalVelosity Posted December 4, 2015 Share Posted December 4, 2015 Get your self a thread gauge http://www.threadcheck.com/ To be sure check the size and gauge of your shower head and check your new one also, that way you will not make a mistake. Also when sealing use loctite 567 and you wont have any issues http://www.loctite.co.uk/loctite-4087.htm?nodeid=8802627092481 Link to comment Share on other sites More sharing options...
mogandave Posted December 4, 2015 Share Posted December 4, 2015 US pipe threads are NPT not SAE. Thailand uses UK thread (BSPT?) Link to comment Share on other sites More sharing options...

I find the Araldite is far better on Thai fittings that teflon thread tape. just sayin. Link to comment Share on other sites More sharing options...
JDGRUEN Posted December 4, 2015 Share Posted December 4, 2015 When it comes to buying actual pipe fittings in Thailand ... the products are made (as per their labels) in China, Italy, the U.S. and various other countries. I have added on/off inline valves to many water pipes to preclude having to shut off the house water supply every time I worked on a sink or commode. And I have found some combinations that perform poorly ... May kitchen and bathroom sink faucet fixtures are so cheaply made that I have to take great care when snugging up the tightness of a replacement unit so as to not destroy it .... Plumbing in Thailand when using various off the shelf fittings is a real experience. As for sizing - I have found most available fittings use INCH measurements ... however I have no clue about the thread sizing and the thread angles involved ... I also found a brand of the plastic plumbers tape in 1/2 wide or so widths and it is GREAT... forget wrapping around and around -- just a short piece a few inches long and presto I'm done...

Thanks, sounds like if I need an adapter over there for a U.S. made shower head, I might be able to find an adapter piece right in Thailand. I have no idea what the thread size on my condo shower pipe is. I'm trying to soften up the hard Thai water in the shower that dries out our hair so badly when we're over there with a quality U.S. made shower water filter/wand.

petermik Posted December 4, 2015 Share Posted December 4, 2015 US pipe threads are NPT not SAE. Thailand uses UK thread (BSPT?) Dont think so BSPT............British Standard Pipe Taper thread in Thailand its BSP.............British Standard Pipe thread therefore NO taper-but not a problem just load the male thread at the neck with PTFE tape and all is good Link to comment Share on other sites More sharing options...

Loctite 567 is like toothpaste and only seals when the fitting is tightened, but allows you to undo the fittings at any time. Araldite does not seal it a cementing agent that is rigid and is prone to heat e.g expansion and contraction of dismmilar materials and temperatures, if you need to change fittings in the future you may damage the fitting threads, then have an issue with re sealing again. Just sayin!!!! Link to comment Share on other sites More sharing options...
CGW Posted December 4, 2015 Share Posted December 4, 2015 (edited) Bring some liquid teflon with you, very hard to find here, if you use it along with tape you have a fair chance of getting a seal! as stated Thai threads are cut to a "strange" profile that resists sealing!!

lopburi3 Posted December 9, 2015 Share Posted December 9, 2015 Having used 50-60 psi here for the last decade there has been no issue of leaking from just using normal teflon tape on connections (yes you may need a bit but it does work and makes it very easy to replace).

Ive found the half inch females even with Brass inserts can often split when using ptfe as the amount needed is horrendous to stop a drip, i get no problems at all with 3/4 females and ptfe tape, but now i also slop ina bit of that gunk and leave it to go thick and sticky before ptfe tape Edited December 11, 2015 by kannot Link to comment Share on other sites More sharing options...
lopburi3 Posted December 11, 2015 Share Posted December 11, 2015 All my taps are 1/2" brass insert (more than 20) and have never had any fail or drip once tightened with tape - did have some blown 90 elbows where contractor did not also make tight when using solvent when first switched to 60psi Grundfos pumps however.

puuchaibaa Posted December 11, 2015 Share Posted December 11, 2015 Common household fittings here are 1/2" which Thais refer to as size 4 (as in 4/8"). I believe the common size in the US is 5/8", or at least that's what came with the bidet hardware I bought in the US and brought over. I looked all over for an adapter but couldn't find one here. Hard to find even on Ebay or otherwise really expensive. The in-laws ended up cutting the US hose in half and wedged into a Thai hose also cut in half and clamped them together. I'd advise you to buy the adapters in the US before you come over. Link to comment Share on other sites More sharing options...
mogandave Posted December 12, 2015 Share Posted December 12, 2015 5/8" is not a common pipe thread in the US. Link to comment Share on other sites More sharing options...
billd766 Posted December 13, 2015 Share Posted December 13, 2015 UK 15mm pipe fittings are the same also as Thai half inch although Thai threads are sloppy poorly manufactured needing tons of ptfe tape 1 inch UK is 25.4 mm so a 1/2 inch thread would only be 12.7 mm which is 2.3 mm smaller than 15 mm. Yes you would need lots of ptfe tape to fill that gap. Link to comment Share on other sites More sharing options...
mogandave Posted December 13, 2015 Share Posted December 13, 2015 1/2" refers to the ID of the pipe. Link to comment Share on other sites More sharing options...
