Thermal fuse for Master Appliance tools
The Master Appliance 50927 thermal fuse and shrink sleeve protects compatible heat tools from overheating during prolonged use. It is a direct replacement component for professionals who rely on Master Appliance equipment for shrink-wrapping, soldering or paint-stripping tasks. The accessory restores factory safety limits without modifying the tool.
Red sleeve signals correct installation
The red shrink sleeve provides a clear visual cue that the fuse has been fitted and shrunk into place. This colour coding helps technicians verify the repair at a glance during routine maintenance or between jobs. The compact broach-style form factor keeps the tool’s balance and handling unchanged.
Replaces blown fuses in AH-series guns
This part replaces a failed thermal fuse in Master Appliance models AH-301, AH-302, AH-501, AH-502, AH-751 and AH-752, as well as Grainger-listed equivalents 1YMJ9, 4Z717, 4Z718, 5PYR0, 5PYR1 and 5PYR2. It is not suited for tools outside these series or for applications requiring a higher temperature rating.
