per EACH (USD)Tube Nut, -4 AN, Stainless
Stainless steel -4 AN tube nut, 7/16"-20. Turns the concave-seat PTFE crimp nipple into a -4 AN JIC female hose end.
The Racetronix FIT-CPNUT4SS is a stainless steel -4 AN tube nut (7/16"-20). Slide it onto the hose before crimping and it holds the 37° concave seat of the FIT-CP4SS crimp nipple against a -4 AN JIC male fitting. The complete FIT-CP4FSS kit includes this nut with the crimp end and collar.

Frequently asked questions
When do I fit the nut?
Before you crimp the collar: slide it onto the hose with the threads toward the cut end.
Do I need thread sealant?
No. The joint seals on the 37° flare. Do not put Teflon tape or sealant on it.
