DESCRIPTION
Gas lines are needed to connect compressors to cold heads (expanders) to complete the
system. Gas lines are constructed from helically corrugated stainless steel tubing covered with
metal braid or from soft copper tubing. All gas lines are equipped with Aeroquip self-sealing
couplings and are furnished cleaned, charged with helium gas and leak checked.
Each cryogenic system includes interconnecting gas lines to carry helium gas refrigerant to and
from the components. A gas line carries high-pressure gas from the compressor to the cold
head and another gas line returns lower pressure gas to the compressor.
Flexible gas lines simplify installation. The self-sealing couplings maintain the gas charge and
purity by minimizing gas loss when connections are being made or broken and by preventing
the entrance of contaminants. Dust plugs protect the coupling threads from damage and also
help to maintain cleanliness.
