Air Breathing Hose
G929 is used for air breathing lines and is designed to resist
permeation of noxious gasses into the hose. The method
of manufacture and compounds used ensure a solvent and
silicone free hose with low odour. This hose has been tested
and satisfies the “off-gassing tests” as described in U.S.
Military specifications MIL-H-2815F Sections 3.12.2 and
4.5.10. G929 also has been tested in accordance with U.S.
Mine Safety and Health Administration Regulations and has
passed the gasoline permeation tests as described in 30CFR
Part 11 Subpart J, 11.124-7. When suitably coupled with
fittings, this hose satisfies the requirements for hose used
on Type C Supplied-Air Respirators. A Type C respirator is
for entry into and escape from atmospheres not immediately
dangerous to life or health. It consists of a source
of breathing air, a hose, a detachable coupling, a control
valve, orifice, demand valve or pressure demand valve, and
an arrangement for attaching the hose to the wearer and
a face-piece, hood, or helmet.
