Wire-to-Wire Splicing
SolderSleeve wire splices
Applications
In-line wire splices.
Features and benefits
Transparent polyvinylidene fluoride or polyolefin
sleeve provides encapsulation, inspectability, strain
relief, and insulation.
Prefluxed solder preform provides a controlled
soldering process.
One-piece design makes installation easy and
lowers the installed cost.
With one or two wires per end, the NAS 1744
splices meet 75,000-ft (22,000-m) altitude
immersion requirement.
Thermochromic temperature indicator in the NAS
splices facilitates termination and inspection.
UL and CUL recognized
