Solder/Heat Seal Splice Kit (40pk)

The Solder/Heat Seal Splice Kit (40pk) from PERTRONIX IGNITION is an essential electrical connector solution designed for serious automotive restoration and engine modification work. Whether you're building a custom ignition harness, upgrading a classic muscle car's electrical system, or repairing corroded wiring in vintage vehicles, this 40-pack splice kit provides the connectors needed to create reliable, durable connections. Mechanics and fabricators rely on proper splice terminations to ensure voltage delivery remains consistent, especially in high-performance applications where electrical resistance can degrade ignition timing precision and fuel injection calibration.

Each solder/heat seal splice in this kit combines two critical connector methods into one reliable design: the solder joint creates a permanent, low-resistance electrical bond, while the heat-shrink seal provides mechanical protection and insulation against moisture intrusion and vibration-induced loosening. This dual-approach termination is superior to crimp-only connections in demanding environments, particularly when working with alternator leads, distributor wiring, or custom engine harnesses where thermal cycling and engine vibration pose constant threats to connection integrity. The compact 3.55 x 1.25 x 5.9 inch packaging contains 40 individual splices, offering sufficient quantity for complete harness rebuilds or multiple repair jobs without excess inventory waste.

Professionals installing electronic ignition upgrades, retrofitting fuel injection systems into carbureted engines, or restoring wiring harnesses in pre-1980s vehicles benefit most from this PERTRONIX IGNITION splice kit. The solder/heat seal design accommodates standard automotive wire gauges commonly used in ignition, charging, and fuel system circuits, making these splices compatible across nearly all engine modification projects. Installation requires only a soldering iron and heat gun—tools every serious wrench turner already owns—ensuring this kit integrates seamlessly into existing shop procedures and delivers connections that outlast the vehicle itself.
