    Hard to find 9/32" OD 4AG/ABS/AGS Series Buss and Littelfuse Fuses Hard to find 9/32" OD 4AG/ABS/AGS/MDC/MDM Series Especially designed to withstand vibration, shock, fatigue and repeated off and on circuit operating conditions. The 4AG series fuses are commonly specified in older aircraft. About 30 years ago Buss superseded them to the now obsolete AGS series fuse. Even this newer series is now leaving many aircraft owners struggling to find replacements. The AGS & 4AG fuses are now being replaced by ceramic ABS series of fuses that have the same electrical and thermal performance.
