Gilles, Thank you for your inquiry to the PPFA concerning your application of piping for vacuum distillation.

For your application, ethyl alcohol at a slight vacuum and temperature of up to 140F, ABS and CPVC should handle the application quite well.

You may want to consider other thermoplastics that would also handle this application such as PVC (140F is the max, temperature limitation), Polyethylene and Cross-linked Polyethylene (PEX) or Polyvinylidene Fluoride (PVDF).

ABS, PVC and CPVC are cementable while the other plastics can be joined using heat fusion and, or mechanical-type joints (PEX in particular).

Please check the PPFA/TIPS website www.ppfahome.org/tips and click on the manufacturer’s products category to see members who offer these products. If you have further questions, please don’t hesitate to contact us again.

Sincerely, David A. Chasis
