Questions about this item

What wire gauge range fits the 0.128 in barrel inside diameter?

The connector accepts 12 to 10 AWG wire, matching the 0.128 in barrel inside diameter for a secure crimp.

How do you crimp these bare brass terminals, and what step is often missed?

Strip the wire, insert it fully into the barrel, then crimp with a ratchet tool sized for 12-10 AWG; the step often missed is verifying the wire reaches the barrel stop before crimping.

When should the tin-plated brass contacts be replaced in a high-heat environment?

Replace them if discoloration or oxidation appears, or after prolonged exposure near the 347 °F maximum operating temperature, which can degrade the tin finish and crimp integrity.
