EMISSION HOSES AND ROAD TEST KIT
SAMPLE HOSE
A flexible metal probe tip, a spring handle
and a reinforced polyurethane hose combine
to make up the Sample Hose Assembly. This
assembly is responsible for getting an
accurate sample from the exhaust stream. It
should be placed into the tailpipe as far as
the handle will allow. This assures that the
sample is taken from the actual exhaust
stream, with no outside air diluting the
sample. For reliable readings, the hose
assembly should be properly cared for. Avoid
pulling, kinking, crushing or piercing the
hose. Be sure that all connections and fittings
are tight. Frequently run a leak test to
determine if any air leaks are present in the
assembly that could dilute the exhaust
sample.
