2217375-1 is a die set for Ultra-Fast FASTON fully-insulated tabs and receptacles, designed for use with the Ultra-Fast hand tool frame PN S8078-3. This die set is engineered to crimp fully-insulated FASTON terminals across two wire gauge ranges: 22-18 AWG (0.3-0.8 mm²) with a maximum insulation diameter of 5.84 mm, and 16-14 AWG (1.25-2 mm²) with a maximum insulation diameter of 6.60 mm. The tool type is classified as UFHT (Ultra-Fast Hand Tool), providing optimized crimp geometry matching for reliable termination. This die set is ideal for high-volume production environments requiring fast, consistent crimping of FASTON connectors in automotive, industrial, and telecommunications applications where insulated terminals are required.
