For the record, Personally I've always used PVC glue for PVC & ABS glue for ABS. Never thought much about it until today when one of my fellow workers asked if it was o.k. to use ABS glue on PVC? . Obviously I said NO, that's why 1 can is labelled ABS & One PVC. When he asked why not, I drew a blank. I'm sure there is a good reason, perhaps the experts can tell me, so I can relay the info.


Thanks,

 

ABS and PVC glues are solvent based. They melt the plastic and weld them together. ABS and PVC use different solvents. The plastic won't melt properly with the wrong glue.

 

Hi,

See if you can which pipe I use 99% of the time.

PVC (Poly Vinyl Chloride) and ABS (the other stuff) are both made of a different plastic compound. so basically to make a proper weld/bond Each glue is designed specifically for each type of plastic.
Have I ever used PVC glue on ABS ? Yes
Can I guarantee that the pipe will still be bonded in 10 years, No
Have I ever used ABS glue on PVC? Never, I hate the black glue.
Even using PVC glue without primer is wrong. In NH we had to use purple primer for a few years so the inspectors would be able to tell if we used primer. According to the manufacturer if you don't use primer the glue will crystallize in the future. Who knew...
After a few lawsuits the state went back to clear primer.
