Parallel Crimp Profile Vs. Double Crimp Profile



If you do any crimping of terminals (Ring, Quick Connect, Etc.) You may have come across parallel and double crimp profile options. What’s the difference?

Parallel a.k.a. Oval or Single: This crimp profile is generally used with heat shrink wrapped terminals and is the more common crimp profile. This profile does not penetrate the insulation and creates a watertight seal. This option, while preferred, is generally more expensive.

Double-Crimp: This option crimps down on both sides of the terminal and creates a winged look after the crimp is complete. As opposed to the alternative, this option can often penetrate the insulation but if a watertight seal is not needed provides a tighter crimp on nylon insulated terminals.
