PVC Fittings for Sewer Pipe

Posted By John Houle on Nov 7, 2017

My tech brief on PVC sewer-pipe fittings begins by comparing outside-diameter controlled dimensions (“OD-controlled”) to inside-diameter controlled dimensions (“ID-controlled”). While this discussion is somewhat dry, it provides essential background information.


The rest of the brief investigates five ASTM standards for PVC sewer pipes and their associated PVC fittings. Three of the standards are OD-controlled and two are ID-controlled. Two are for solid-wall pipe and the other three for profile-wall pipe.

Information included for each standard includes:

  • Size range
  • Joint types
  • Fittings production methods
  • Other referenced ASTM standards that must be met
