Parker Safety Guide for Selecting and Using Hose, Tubing,
Fittings and Related Accessories, Section 2.6:
Permeation:
Permeation (that is, seepage through the Hose) will occur from inside the
Hose to outside when Hose is used with gases, liquid and gas fuels, and refrigerants
(
including but not limited to such materials as helium, diesel fuel, gasoline, natural gas, or
LPG). This permeation may result in high concentrations of vapors which are potentially
flammable, explosive, or toxic, and in loss of fluid. Dangerous explosions, fires, and other
hazards can result when using the wrong Hose for such applications.
The system designer must take into account the fact that this permeation will take place
and must not use Hose if this permeation could be hazardous. The system designer must
take into account all legal, government, insurance, or any other special regulations which
govern the use of fuels and refrigerants. Never use a Hose even though the fluid compati-
bility is acceptable without considering the potential hazardous effects that can result
from permeation through the Hose Assembly.
Permeation of moisture from outside the Hose to inside the Hose will also occur in Hose
assemblies, regardless of internal pressure. If this moisture permeation would have detri-
mental effects (particularly, but not limited to refrigeration and air conditioning systems),
incorporation of sufficient drying capacity in the system or other appropriate system safe-
guards should be selected and used.
