Sounds like a PA nva made by Nelson, Randy Smith from Aero Products might be able to help.

Rusty you might check Mecoa for K&B parts.  They own the franchise and can likely get you a replacement NVA.

Hello,

I was wondering where I could get a needle valve assy for a K&B Torpedo 35 green head?

I have some modern needle valve assemblies (unknown who made them) that have a white nylon compression cone to hold the setting.  It is compressed by a nut similar to a supertiger.   Where can I get some of these nylon cones?

Thanks

can you post a picture of what you have?

The bottom one is mine,  have the  needles, lock collets, delrin seals, and nuts for that bar
I have standard size ones complete, what you have on the Stainless steel one is a PA one for a FOX 35

That other nva has a split body. You tighten the cap down to set the drag and it seals on the threads like a SuperTiger nva. The inside of the cap should have a conical shape to squeeze the split line closed. I don't think it uses a nylon insert.
