PREFORMED LASH SPLICE
A ready-to-use helical splicing solution guaranteeing mechanical strength and electrical continuity in high-vibration mission-critical systems.
Preformed Lash Splice is a ready-to-use helical splicing solution that transforms manual wrapping techniques defined in NASA-STD-8739.4A standards into an industrial component, guaranteeing mechanical strength and electrical continuity of solder connections in high-vibration, mission-critical systems.
- Uninterrupted Electrical ContinuityHigh-purity tin-plated copper structure prevents signal/power losses and resistance rise.
- Maximum Vibration & Armor ProtectionHelical armor sleeve absorbs environmental stresses and engine vibrations, eliminating solder cracking.
- Domestic Production & Flexible SizingFully compliant with military/aerospace specs (SAE AS81824, MIL-STD-2000), short lead times and custom dimensions.

MECHANICAL TENSILE TEST & SAE AS81824 COMPARISON
Axial tensile tests conducted at Gebze Technical University Materials Science and Engineering Laboratories verify that Preformed Lash Splice exceeds SAE AS81824 crimp thresholds.
100% Splice Efficiency: Failure occurred in the free copper wire outside the splice—zero joint slipping.
+23% Safety Margin: Exceeded crimp standard thresholds by 23%, maintaining 100% carrying capacity.
