Pressure Rating

N/A Burst Pressure ratings at ambient 70ºF (21ºC). See below on vacuum/pressure ratings at temperatures other than ambient.
Working pressure is given at room temperature. Decrease working pressure to 50 psig for all sizes above 175 ºF.
Vacuum rating all sizes: 29.9" Hg @ 70 ºF. Decrease working pressure rating 1% for every 2 ºF above 175 ºF. 1-1/2" rated @ 24' Hg; 2" rated @ 20" Hg when installed less than 2X minimum bend radius.

  • 1 Working pressure is given at room temperature. Decrease working pressure to 50 psig for all sizes above 175 ºF.
  • 2 Burst pressure ratings at ambient 70 ºF (21 ºC). See below on vacuum/pressure ratings at temperatures other than ambient.
  • 3 Vacuum rating all sizes: 29.9" Hg @ 70 ºF. Decrease working pressure rating 1% for every 2 ºF above 175 ºF. 1-1/2" rated @ 24' Hg; 2" rated @ 20" Hg when installed less than 2X minimum bend radius.
