HYREDUCER™ typeYRB reducer butt splice
is designed to splice two different conductor
sizes and is UL listed for aluminum to copper
and aluminum to aluminum applications. The
outside diameter is held constant to minimize
installation dies and is factory prefilled with
PENETROX™.
Features and Benefits
• Solid center barrier.
• Constant outside diameters. Electro
tin-plated.
◊ Minimizes installation dies and provides
a smooth profile for easy taping.
Provides durable long lasting
◊ Provides center stop for correct cable
insertion and aids the thorough penetra-
tion of PENETROX™ oxide inhibiting
compound between conductor strands.
• Connectors are clearly marked with cata-
log number, wire size, and color-coded
die index.
◊ Provides clear, easy to use information
to lower installed costs.
• Each barrel end has a plastic end cap.
◊ Keeps the connector barrels free of
foreign materials.
corrosion resistance.
