Burndy U164 Hydraulic Crimp Die Set U Type Index

The Burndy U164 hydraulic crimp die index is a stainless steel twin U-type die set used with Burndy hydraulic crimpers, designed for reliable U‑series crimps in electrical connections. The set is identified by die indices 164 and 275, and is commonly described in official catalogs as the U164/U275 twin-die configuration, reflecting two dies in one indexing assembly. It is intended for crimping circular butt connectors on electrical conductors using Burndy’s U‑series tooling, providing a precise, repeatable crimp profile when paired with compatible hydraulic equipment. Catalog references show U164 among the Burndy die index family alongside W164 and other related dies, confirming its place within the broader U‑die indexing system.
