A listing marked 1/8 needs both a unit and a dimension reference. If it means 1/8 inch, the measurement is 3.175 mm; confirm whether that refers to the passage, mounting hole or another feature.
Use the drawing to check panel thickness, groove dimensions and flange clearance. Small parts still require appropriate handling and the specified installation method. Do not assume no tools or instruction will be needed.
Select the compound for the temperature and exposure. Size and general material quality do not establish resistance to all chemicals, weather or mechanical damage.
