Purple U-Style Crimping Die

The Burndy U28RT is a purple-coded U-style crimping die set for copper lugs up to 4/0 AWG. It delivers an upper and lower die pair built for 12-ton compression tools. The die matches the purple connector colour code used in standard electrical installations.

Suits installers with U-series 12-ton tools

Electricians running PAT46, PAT750, Y35, Y39, Y45, Y46 or Y750 crimpers can use this die directly. Teams needing dies for larger lugs, different colour codes or non-U tool series should select another die set.

12-ton U-style die for 4/0 AWG copper

The single specification that decides fit is the 12-ton U-style rating combined with the purple 4/0 AWG capacity. If the tool supplies 12 tons and accepts U-series dies, this set will crimp purple-coded 4/0 copper lugs to specification.

Questions about this item

Will the 12-ton crimping force wear the purple U28RT die enough to require replacement?

The die is hardened steel built for repeated 12-ton compressions on 4/0 AWG copper lugs; replacement is only needed if the die profile shows visible deformation or cracking.

What limit appears first when making continuous crimps with the U28RT on a PAT750 or Y750 tool?

The 12-ton capacity of the die is the hard limit; the tool’s hydraulic system will reach its pressure ceiling before the die itself fails.

Does the U28RT die generate noticeable heat or noise during all-day use with a Y35 or Y46 crimper?

The die itself produces no noise or heat; any warmth or sound comes from the crimper’s pump and handle operation, not from the die.
