Replacement Nut, -8 PTFE Hose End, Blue

Spare nut for Racetronix -8 PTFE hose ends.

The Racetronix FIT-TFNUT8BL is a replacement nut for our -8 reusable PTFE hose ends, blue anodized. Use it to replace a damaged nut or to colour-code a line. The ferrule (olive) is sold separately as FIT-OLIVE8B.

Key features

  • -8 PTFE hose-end nut.
  • Blue anodized.
  • Fits Racetronix reusable PTFE hose ends of the same size.
  • E85 compatible.
  • 6061-T6 aluminum, blue anodized.
Fitting it

The nut slides over the hose before the ferrule goes on. On an existing joint the ferrule stays seated in the old nut, so changing the nut means cutting the hose back and fitting a new ferrule.
