RF Industries RFA-4009-03 — Interchangeable Crimp Die Set
The RF Industries RFA-4009-03 is a precision interchangeable crimp die set designed for use with the RFA-4009-20 heavy duty piston action crimp handle. Manufactured by RF Connectors, a Division of RF Industries, Ltd. (San Diego, CA), this two-piece steel die set features three hex crimp cavities — .042", .068", and .255" — making it compatible with Cable Groups D, P, and X, including commonly used coaxial cables in the LMR-240 size range.
The RFA-4009-03 die set installs and locks directly into the open-frame rail of the RFA-4009-20 handle in seconds, allowing technicians to quickly reconfigure a single crimp handle for different cable types and connector sizes without the need for multiple complete tools.
Key Features
- Three Hex Crimp Cavities: .042", .068", and .255" cavity sizes stamped directly on the die faces for fast, error-free cavity identification.
- Compatible with RFA-4009-20 Handle: Drop-in fit via bottom rail slot — no tools required for installation.
- Cable Group Coverage: Designed for RF Industries Cable Groups D, P, and X, including cables in the LMR-240 size class.
- Removable Lock Pins Included: Supplied with removable lock pins for permanent, secure die retention in the crimp handle during high-volume production use.
- High-Quality Steel Construction: Manufactured from high-quality steel for long service life and repeatable crimp geometry.
- Cavity Markings Stamped on Die: All three cavity dimensions (.255, .068, .042) are clearly stamped on both faces of the die set for quick identification during use.
- Two-Piece Die Design: Upper and lower die halves align precisely within the RFA-4009-20 frame for consistent, centered crimping force.
