Specifications

Terminal Type Supported AWG Die/Crimp Profile Ratchet/Adjustment Included Parts
Compatible spark plug and ignition-wire terminals Not specified by AWG; 8–8.5 mm ignition-cable diameter Single- and double-crimp terminal positions with wire-stripping holes Ratchet mechanism, adjustable star wheel, and quick-release lever 1 crimping tool, SKU HX1220

The 8–8.5 mm specification describes ignition-cable diameter, not conductor AWG. Confirm the cable construction and terminal requirements rather than converting the outside diameter to an AWG size.

❓Which terminal types are compatible?
Compatible spark plug and ignition-wire terminals for 8–8.5 mm ignition cable, using the tool's single- or double-crimp terminal positions. Confirm the exact terminal geometry and manufacturer's required profile; the tool is not universal.

❓What AWG range is supported?
No universal AWG range is specified for this product. It is rated by 8–8.5 mm ignition-cable diameter. Cable outside diameter must not be treated as conductor AWG.

❓How do I select the correct die/profile?
Match the terminal's single- or dual-crimp design and dimensions to the corresponding jaw section. Follow its crimp specification, test a sample, and inspect the finished connection before final assembly. Do not use ratchet pressure adjustment to compensate for a mismatched profile.

❓How to Choose

Check the ignition cable diameter first: this listing supports 8–8.5 mm cable. Identify whether the terminal requires a single or dual crimp, then match its crimp wings and required finished profile to the correct jaw section. Follow the cable and terminal manufacturers' strip-length, core-preparation, and crimp requirements. Ratchet adjustment cannot make an incompatible terminal fit the die.

For other terminal families, compare our wire crimping tools. General harness contacts may require an open barrel crimping tool for non-insulated terminals; this does not establish compatibility with spark plug terminals.

❓How to Use

  1. Switch off the engine, allow hot parts to cool, and isolate the ignition system as instructed by the vehicle manufacturer. Never work on a running or energized ignition system.
  2. Confirm cable and terminal compatibility. Prepare any boot and strip the specified length using the matching stripping hole without damaging the ignition-wire core.
  3. Prepare the exposed core exactly as directed by the cable and terminal manufacturers. Position the terminal in the matching single- or dual-crimp jaw section.
  4. Seat the cable and terminal correctly and complete the ratchet cycle. Use the quick-release lever if repositioning is needed.
  5. Inspect the terminal crimp, check retention as specified, and assemble the boot. Complete the cable manufacturer's required electrical checks before returning the ignition system to service.
