Pipe Extractor

[GarryP]

Does anyone know where I can buy a 1/2" pipe extractor or internal pipe nipple wrench in Bangkok? I have checked the mom and pop hardware stores and HomePro but turned up blank. 

 

The devices/tools are used to remove the broken portion of the thread which is left embedded in the joint with, for example, a water pipe. Sometimes, when removing a tap which is screwed into a pipe which is embedded in the wall, the threaded part of the tap breaks off and remains in the pipe junction. Before you can put in a replacement tap, you need to remove the broken part of the tap, which can be a pain in the bum if you don't have the right tools and can seriously damage the thread in the embedded pipe - something to be avoided.

A needle nose worked for me.  Took a while picking at it, but finally opened up.

Once had a Thai plumber come round to my son's house. He used a hammer and a very small chisel type tool, which he used to slowly chip away the old pipe. Resulted in damage to the female thread, took an age and resulted in cuts to the hand of the plumber. 

 

I did a bit of research and found that there are specific tools for this job, but haven't been able to find them here. Hence the question. I have a few taps that need replacing and their quality is pretty poor so I want to have the tool in hand before I go ahead.

I have seen proper ring grip nipple extractors in Hardware House.

Alternative is to try purchasing a single cheap Chinese screw extractor down at the Khlong Toei tool shops.

Could use one of these I did. ????

If you decide to go with a proper tool do not use the type above as they work by screwing in to the stub and expanding the stub making it even tighter. OK on thick wall but no good on thin wall. Buy a 4 sided taper extractor. I have removed a broken stub with a flat piece of steel with a slight taper ground on and lightly hammered in then turned

That is one method. I read that a flat tapered steel file works well, but I don't have one at the moment so thought it best to buy a specialist tool instead.

It looks like a concrete anchor to me.     Wonder how it works as an extractor?

Thanks. I don't know why I had not thought of Lazada. I have bought other stuff via Lazada so I have no idea why I did not think of it this time. Must be getting old.
