BURNDY U34RT U Connector Die
The BURNDY U34RT is a heavy-duty stainless steel circular butting twin U-die engineered for terminating 500 kcmil copper conductors. Designed for fast and accurate field identification, this die is color-keyed BROWN and permanently stamped with die index 20. It consistently delivers a 12-ton compression force to ensure reliable, high-quality connections when installing BURNDY HYLUG™ compression terminals and HYLINK™ compression splices in the YA and YS series.
Constructed from high-grade stainless steel, the U34RT die strongly resists corrosion and wear, ensuring exceptional durability and a long service life in harsh field or shop environments.

- BURNDY Y35 Series
- BURNDY Y39 Series
- BURNDY Y750 Series
- BURNDY PAT750-18V Series Crimpers

Frequently Asked Questions
Q: Do I need an adapter to use the U34RT die with a PAT46-18V tool?
A: Yes. While the die fits Y35, Y39, Y750, and PAT750-18V tools directly, using it with the PAT46-18V or Y46 15-ton tools requires a PUADP-1 die adapter (sold separately).
Q: What type of terminals is this die designed to crimp?
A: The BURNDY U34RT is designed to install BURNDY HYLUG™ compression terminals and HYLINK™ compression splices in the YA and YS series onto 500 kcmil copper conductors.
Q: How do I verify I am using the correct die in the field?
A: The die is permanently stamped with the die index (20) and is color-keyed BROWN for fast visual identification matching the corresponding compatible connectors.
