Pintle in french?

Hi,

How would you translate "pintle" in Canadian french. Here is the full sentence: "While the color, pintle, filter and/or part number may be different from the original, the performance and electrical characteristics are identical." It talks about a fuel injector. Thanks!

Aiguillot maybe?

Je crois que cela dépasse l'entendement... merci quand même:p

I don't fully understand how the product is, but "aiguille" or maybe "pivot" are options.
