luudee Posted March 15, 2017 Share Posted March 15, 2017 (edited) Hi Guys, I am looking for a fitting like in the attached Picture. I need a 2 inch piece with the threaded part made from brass, like that smaller 3/4 inch piece. Any idea where to find such a thing ? Preferably Pattaya and surrounding area, but will consider mail order as well. Many Thanks, rudi PS: I checked all the usual stores in Pattaya ...

carlyai Posted March 15, 2017 Share Posted March 15, 2017 Did you check in the big Global House store outside Pattaya in Rayon or near Satahip? (from what I remember ).If they don't have it, I'm sure they will order it, if available, but takes a few weeks.Sent from my SM-J700F using Tapatalk Link to comment Share on other sites More sharing options...
Artisi Posted March 16, 2017 Share Posted March 16, 2017 (edited) Arjen. If you pulled the brass section from the PVC, you have applied excessive torque (overloaded the brass / PVC interface) use a lot less muscle power or a shorter pipe wrench.

Ace of Pop Posted March 16, 2017 Share Posted March 16, 2017 Yes ,just put Superglue in on all brass inserts.Not that stuff they use.Sent from my iPhone using Thaivisa Connect Link to comment Share on other sites More sharing options...
chickenslegs Posted March 16, 2017 Share Posted March 16, 2017 (edited) I haven't seen a 2 inch version of that pvc/brass fitting anywhere - but I haven't been looking specifically. Hardware House, Ban Amphur (East side of Sukhumvit road, not far past Ambassador City Hotel) has a good range of PVC fittings. Back of the store on the far left. Can I ask why you need a brass fitting. Edited March 16, 2017 by chickenslegs Link to comment Share on other sites More sharing options...

The pump (self-priming) might get a bit warm at times, which causes the PVC thread ending to shrink and pop out. I'm open to other ideas ...

(picture attached) Thanks, rudi I have 2 Hayward pumps, each with the same 'male' blue pvc fitting as yours. Never had a problem with popping out. If you don't find the 2" brass/pvc fitting maybe some better quality (thicker) PTFE tape would solve the problem. Link to comment Share on other sites More sharing options...

I will try one more time a PVC fitting ! rudi Link to comment Share on other sites More sharing options...
carlyai Posted March 17, 2017 Share Posted March 17, 2017 You could also try a higher grade of pipe. I think there are 3 grades in Thailand. The corner shop grade, 8.5 grade and 13.5 grade. (I think it's 13.5). The pipe and fittings are thicker in the higher grade.You have to make sure that the higher grade fitting will fit into the pump. Some fittings you cannot use 13.5 grade as will not fit.Try and buy an 8.5 and 13.5 grade threaded bit for the pump and see which one fits.The pipe glue should be good quality glue, and it is recommended (though I haven't ever done it) to use a pvc pipe cleaner, like nail polish remover to make for a better joint.

Artisi Posted March 18, 2017 Share Posted March 18, 2017 Irrespective of pipe grade, the outside diameter of the pipe is the same therefore all fittings have the same dimensions. Link to comment Share on other sites More sharing options...
leyali Posted March 18, 2017 Share Posted March 18, 2017 If it get warm, the PVC thread should not shrink, opposite.Put a bit more white tape and screw it fully in, more as on the pic.Yes, there different quality of the glue, I'm very happy with the Thai-Pipe brand. I'm not cleaning with pipe cleaner, but I always sanding the pipe with sanding papers, so the glue can stick better. Link to comment Share on other sites More sharing options...

It is screwed in pretty much to the end. This actually brings up a good point. The PVC fitting has a bit of "dead area" before the thread begins. I am considering to cut that off ... rudi Link to comment Share on other sites More sharing options...
Crossy Posted March 18, 2017 Share Posted March 18, 2017 I would use a 2" PVC female threaded fitting and a 2" male-to-male threaded in iron or brass. That should provide some thermal isolation, or even get a length made up in iron pipe. That said, all our pumps have plain PVC threaded into them (with loads of tape of course) and I've never had an issue with things popping out. If your pump is getting warm enough to damage the PVC there's something awry with the pump. Link to comment Share on other sites More sharing options...

I apply the tape, then screw the union in by hand, remove, then reapply tape, each time using far more than what would be considered "normal" most times I get a good seal!

carlyai Posted March 18, 2017 Share Posted March 18, 2017 Irrespective of pipe grade, the outside diameter of the pipe is the same therefore all fittings have the same dimensions. Well that may be true, but evidently, I can't fit 13.5 grade pipe to my pool water fittings as they won't fit. I have to use 8.5 grade through the pool walls, to connect to the pool fittings or they won't fit. So, to me, there is something about the thickness of the pipe that has a bearing on what fittings fit. I haven't received all my pool parts yet, so I can't say from experience, just from advice received. Sent from my SM-J700F using Tapatalk Link to comment Share on other sites More sharing options...

Yes, thanks, then it must be the ID that causes a problem with the pool fittings.As you say regardless of the thickness that won't affect the connection to the pump. Anyway, he's using 13.5 grade already.[emoji3]Sent from my SM-J700F using Tapatalk Link to comment Share on other sites More sharing options...
