All components and parts have been
selected by Air Products to be compatible
with the gas or gases to which they may be
exposed. This is particularly critical for
the softgoods (i.e. o-rings, valves, seats and
seals, etc.) It is critical that replacement
components and parts be identical to the
original item to avoid hazardous
malfunctions or leaks. Consult Air
Products if there is any question about the
part to be used and its compatibility with a
particular gas.
