Gamma-Mark Heat Shrinkable Wire Markers

Both MARK-221 & MARK-321 meet the stringent requirements of AMS-DTL-23053/5 CL1&3 and the mark permanence of SAE-AS-81531 before and after shrinking. Marking on GAMMA-MARK sleeves allows for a permanent mark resistant to abrasion, aggressive cleaning solvents, and military fuels and oils. GAMMA markers are designed to be printed on by a dot matrix or a thermal transfer printer. Markers are held between two perforated plastic strips and are supplied in the standard 2” length. This allows for more accuracy, a cleaner print, and less room for error.
