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.

Select part numbers from the appropriate table: page 8-8. For CWT series (low temperature): Use Table A on page 8-6. For D-110 series (splashproof): Use Table B on page 8-7. For D-1744 series (immersion sealed): Use Table C on page 8-9.

Turn to CMA/mm Calculation on page 8-10 and use the workspace there to calculate the total cross section to be spliced. 2. Use Table E on page 8-11 to select the sleeve recommended for that cross section. Users should independently evaluate the suitability of the product for their application.
