Length
There are many options when it comes to hoses.
The most important aspects for an air compressor
are going to be length, diameter, and fittings. The
material of the hose is also an important consid-
eration, but this will depend more on your applica-
tion and preference.
Choosing Air Hose
Consider your applications before deciding on a
hose length. Longer hoses, or hose connections
to extend hose length, can increase your mobility,
but will probably result in some pressure loss.
If your work area will be small, you may be able
to use a shorter hose without having to move the
compressor. A compressor should be discon-
nected from power and the tank emptied before
being moved, so constant relocation could have a
big effect on operation down-time.
An air compressor becomes very hot during oper-
ation, and the pressure switch and motor often
produce sparks. Some applications, like spraying
or sanding, involve flammable material that cre-
ate a fire or combustion hazard when they are
performed too close to a compressor. The hose
length must allow for the air compressor to remain
at least 20 feet away from the operation.
Diameter
A larger inner diameter will allow for high airflow
delivery. Refer to
Airflow Delivery (CFM) on
Page 19 for more information. The higher CFM a
tool requires, the larger the inner diameter of the
hose will need to be (see
Figure 14).

Fittings
Many hoses come with fittings installed. The sim-
plest option is to find a hose with two fittings: one
that matches the compressor output port, and one
that matches your intended attachment tool. If the
hose does not match the port, a coupler may be
needed.
You will need to determine the size of the fit-
tings and whether they are male or female (see
Figure 15). A male fitting can only attach to a
female fitting, and vice versa. There are also a
number of coupler/plug styles on the market, so
be sure the two match or you will likely not have
an airtight connection.
