zlodnick Posted May 25 Share Posted May 25 I've noticed some of the fittings for pvc water pipes have brass threads. I'm wondering if they are supposed to be better than plastic threads, or are they for a special purpose? Link to comment Share on other sites More sharing options...
OneMoreFarang Posted May 25 Share Posted May 25 I am pretty sure brass fittings are stronger. If the pipes have no pressure than probably plastic is good enough. 1 Link to comment Share on other sites More sharing options...

Plastic has worked fine for pressurized pipe for decades before brass was available. It continues to work fine in most installations. I have a bunch of 20+year old plastic threaded fittings that probably will be good for another 20 years. Link to comment Share on other sites More sharing options...

But be careful that you do not over-tighten the fitting or the plastic surrounding the brass will break. Edited May 26 by GreasyFingers Link to comment Share on other sites More sharing options...
mran66 Posted June 9 Share Posted June 9 In theory better, however I have had 2 separate cases where the in-mold brass thread has cracked leading to leak. Probably would not have had problem with plastic-only one. I will not use brass ones any more due to bad experiences Link to comment Share on other sites More sharing options...
