Blackburn BY37 – Frequently Asked Questions
1) What is the Blackburn BY37 die used for?
The BY37 is an outside-diameter (OD) compression die for crimping lugs and connectors with a hydraulic or mechanical crimping tool. It stamps size code 840, which is the die index you match to the connector manufacturer's crimp chart for the conductor and connector you are terminating.
2) How do I know if die code 840 is the right one for my lug?
Go by the code, not the wire size. Compression connectors are marked with the die code the manufacturer requires, so the BY37 is correct only where the lug or splice is stamped 840. If your connector calls for a different code, that die will not produce a rated crimp, and you need the die matching the marking instead.
3) Is the Blackburn BY37 sold as a single die or a matched pair?
It is sold each, as one die, under part number BY37. Crimping tools that take two-piece die sets need both halves ordered, so check what your tool head requires before you order a single piece.
4) Do I order the BY37 by the die code or the part number?
Order by the part number BY37. The 840 is the size code stamped on the die and referenced on the connector, not the ordering number, so quoting 840 alone can get you a different manufacturer's die.
5) What is the BY37 compression die made of?
Steel, finished black. That is the standard construction for crimp dies that see repeated high-pressure cycles in a hydraulic head.
