| Item No | Dimension(mm) | Wire range | Imax | Color | |||
|---|---|---|---|---|---|---|---|
| L | Dφ | dφ | A.W.G. | mm2 | |||
| BNYF 1.25 | 25.2 | 3.2 | 1.7 | 22-16 | 0.5-1.5 | 19A | Red |

The original descriptive text lists red as 22–18 AWG, while the BNYF 1.25 model table lists 22–16 AWG. The table is retained as supplied; confirm the approved conductor combination before ordering.
Selection Guide
Match both conductors to the model table, then check L, Dφ and dφ against your assembly. Use the model-specific wire range rather than selecting by colour alone.
Strip to the approved length, insert both conductors fully and crimp each end with compatible insulated-terminal tooling. Inspect conductor insertion and retention before use. Nylon insulation does not by itself establish a sealed or waterproof splice.
Applications
Potential uses include cable splicing, equipment wiring, lighting assemblies and wire harness repair where a nylon-insulated crimp butt splice is specified.
Product compatibility and qualification depend on the model, installation process and approved assembly.
Ordering Information
Send the complete BNYF model number, wire sizes, application and order quantity. Include your sample, inspection, packaging and documentation requirements.
