Notes:
* Based on total maximum pressure drop in hose, tubing or piping of 5" wc (1244 Pa)
** Maximum recommended length for vapor hose is 10' (3 m). Longer distances may cause kinking or low spots.
*** To minimize loss of capacity and efficiency, insulate tubing and piping.

Developed length equals measured length plus 50% of measured length, to account for pipe fittings.

Requires flange connection
