Flexible couplings for clay pipe drainage

[Morakot]

I'm looking for flexible couplings to replace a small section of a drainage that is made of standard clay pipes (with male/ female ends).

Where could I find something like shown in this video, here in Thailand? Any ideas?

[Morakot]

Similar couplings come together with those black sceptic tanks. 100mm diameter.

I'd need this for a 200mm pipe.

The one in the picture, is this an adapter? Meaning each site has a slightly different diameter, or is each site 100% identical?

Cheers! Very helpful.

available at thai watsadu and global house

They are sold as "plumbfix flexible couplings" and a few other generic names

I'm sure the locals could provide a fix with fence wire and a tractor inner-tube

I've certainly seen the smaller ones in the major DIY places, not so sure about 200mm

[Langsuan Man]

They are available in larger sizes but I could not find them for smaller sized pipe

I needed several 2 inch ones and had to have them shipped from the US via Shipito

I finally found the right gear for flexible coupling (at Thai Watsadu).

It's inexpensive and quite suitable. The blue cuff is actually used for these massive water pumps and seems extremely durable. These heavy duty clamps are perfect, but I'm not entirely clear about the fasting mechanism. I take it the counter piece with the large nut is to give pressure, ensuring the clamp's main nuts and bolts don't loosen.

Would anyone know, what precisely the nut on top is for? It's much bigger and does not fit the bolt. In fact it cannot be taken taken off. So what is it for?

I think the top nut is intended to be used as a pipe hanger, indeed the whole "clamp" may be a re-purposed pipe hanger

[Sophon]

Yes, definitely pipe hangers meant too secure the blue PVC pipes in place. The top nut is used to insert a galvanized rod that is bought separately and can be cut to size. We used these clamps when building or house.

Thanks very much, gentlemen!

I will let you know the results tomorrow.

[Morakot]

Well, as it turned out these "clamps" not fit properly...

I used something else, but it's not as sturdy as I hoped for. The tube material is perfect though; it's dense and quite flexible (see last photo, for its original purpose). I cut a 2 meter long piece open and wrapped it around several times and used some a pcv pipe to give it some extra support. Now how many decades will it last...
