Where to buy PVC pipes in inch (Not mm)

Anyone knows if any PVC pipes shops sell pipes & fittings in inches?

I went to most of the PVC pipes shops along Jalan Besar, all of them sell PVC pipes & fittings in metrics (mm).

I need to buy PVC pipes in these sizes, 1/2", 3/4" & 1" plus all fittings in 3/4".

Reason why i need these pipes in inches coz i need tight fit when i insert pipes say, 1/2" into 3/4" and 3/4" into 1" (I think so, according to the OD & ID dimensions i found on internet).

The dimensions i found on internet for pipes in inches:
Size-|OD--------|Thickness--|ID-----|
-----------------------------------------|
1/2--|0.840-----|0.109-------|0.622-|
3/4--|1.050-----|0.113-------|0.824-|
1----|1.315------|0.133------|1.049-|
-----------------------------------------|

PVC Pipes in metrics (mm):
Size-|OD--------|ID-----|
15---|21.4------|
20---|26.8------|23.7---|
25---|33.6------|29.8---|
-----------------------------------------|


The corresponding pipes in mm however will not be tight fit when inserting one into another, example, inserting 15mm into 20mm (next bigger size) will be loose and not really suitable for the DIY i am planning to do.

Appreciate if anyone who ever come across shops selling pipes in inches, please kindly let me know. Thanks in advance.

There are many standard of PVC pipe selling in Singapore.
JIS (call it AE, AO in light grey in Colour)
BS (normally in white Colour or light brown colour)
ASTM or call it Schedule 80 (dark grey colour).
So I believed you are looking for "schedule 80" standard.
Lookup the following company see which is more convenient to you.

GLYNWED pipe system,
Landmark plastic,
George Fischer,
Eng Guan hardware,
Aik hock Hardware etc.
 

Thanks a lot for the valuable info, Peterleenc.

So if I understood it correctly, those i saw (in white color) were schedule 40 (thinner) pipe. I should instead be looking at the schedule 80 which is thicker in wall, they should be tight fit if i were to insert the smaller one into the bigger pipe and it really doesn't matter whether they are in inches or mm, right?

The White colour PVC fitting is BS standard. (not schedule 40)

The only PVC fitting label in inches is the ASTM standard for steel pipe they have schedule 10, 40 and 80 available but PVC pipe only schedule 80 available in Singapore.
 

Thanks again. Really appreciate your helps and learnt a lot from you.. :-)

I will try to source around Jalan Besar (near to my working area) as those companies suggested by you are pretty far (Loyang/Changi/Tampines..).

JIS is Japanese Standard - not sure what unit they using, most likely metric...
BS is British Standard - in metric unit.
ASTM is American Standard, which is the main supporter for imperial unit now...

Pipe manufacture to ASTM should be in imperial unit.
 

Sounds interesting. What you wanna DIY? Actually the thread sounds like plumbing forum LOL.
 

Thanks.
