Description
The 1990 Hydraulic Crimping Tool is a hand-held, self-
contained dieless crimping tool intended to crimp
aluminum and copper connectors onto electrical cable.
The hinged crimping head, which allows easy loading
and unloading of splice connections, swivels 180
°
for
maximum flexibility. The two-speed hydraulic system
automatically switches from rapid advance (for quick
snug-up) to normal advance (to accomplish the crimp).
An internal pressure regulating system automatically
sets the correct pressure for the connector.
This tool is cUL and UL classified for use as directed on
the cUL/UL Table provided in this manual and on the
carrying case.
The 1990 Crimping Tool is protected by US Patent No.
