2.5.2 Beveled Nozzle Tool (6.5" and 24")
For simple pin-hole type leaks, position this attachment directly over the leak source.

2.5.3 Capture Bag
This reusable capture bag measures 36" x 36" and can be used to completely surround a
component that may have multiple leak sources, or contains a leak source that is
difficult to pinpoint or reach.
Attach the Hi Flow
 Sampler’s main sampling hose to the bag by simply pushing the end
of the hose into the bag’s hose coupling. A click should be heard when the hose has
been successfully connected. Release the hose by pushing in the coupling’s release
mechanism.
Use the draw strings to close up the end of the bag. DO NOT, however, completely close
off the bag – allow air to flow into the bag so as to replace the volume of gas and air
being removed during the test.
