How-To Install A Sanborn Regulator Repair Kit 105-0004
This short video shows how to install a Sanborn 104-0005 regulator repair kit on a Sanborn air compressor.
105-0004 - Regulator Repair Kit (Diaphragm Installation):
• Replace the original diaphragm with the same color diaphragm provided in the kit.
• If the original diaphragm is not available (i.e. lost, damaged, or other) then install the black one, first. If air leaks out, then replace it with the white diaphragm.
• Air will leak out if the wrong diaphragm is installed.
Master Tool Repair recommends having the unit repaired by a certified local service center if issues persist.
