MATERIAL DESCRIPTION
PVC (Polyvinyl Chloride)
Xirtec 140 PVC used in the manufacture of Schedule 40 and 80 fittings is of Type I, Grade 1 compound
(cell classification 12454) as stated in ASTM D1784. The maximum service temperature for PVC is
140ºF (60ºC) under pressure, with occasional exposure to boiling water (212ºF, 100ºC). With a
hydrostatic design basis of 4000 PSI at 73ºF (23ºC) and a design stress of 2000 PSI at 73ºF (23ºC)
PVC has the highest long-term hydrostatic strength of any major thermoplastic material used for piping.
