Our refillable cylinders are made of steel
or aluminum, and are designed for refilling
and repeated use. Some cylinders have
been in service for over 40 years!
refillable cylinders have an open interior
with walls of 1/4 inch steel
and a reinforced neck
and bottom. Because commonly used gases
are highly pressurized (between 1,500 psig and
2,500 psig), cylinders must be
good condition and protected
from accidental damage at all times.
