I recently bought some needle-valve extensions (yellow) designed for Killer Bee needles, with the intent to replace the "black knobs" on some of my standard (product-engine) needles.

Here's my issue..

Apparently; a Killer Bee's needle-stem diameter is a lot smaller. Good thing I bought two packages... Crying or Very sad

I wish... Laughing

The inside diameter is .070" and the diameter of a product-engine needle is .125" at the knob-end....... What I need is a similar material tube with a 3mm (.118") inside diameter. That's what I had assumed these yellow tubes were.

Yeah, the Killer Bee end that accepts the yellow extension is about 0.080" (post knurl). Both the regular ones and Killer Bee are run from raw stock of 1/8" brass. Absent the look there is no difference in the thread specs.
