Adapter, -4 AN ORB Male to 10 mm (3/8") Multi-Barb for Nylon Fuel Tube, Black

Converts a -4 ORB port to a 10 mm (3/8") nylon fuel tube barb.

The Racetronix ADF-MBM10RM4 connects 10 mm (3/8") nylon fuel tube to a -4 AN ORB port.

The multi-barb is shallow and sharp with tight spacing, made to grip and seal Racetronix nylon convoluted fuel tube with an Oetiker ear clamp. A tall, rounded rubber-hose barb does not seal well on nylon tube. It also works well with rubber hose.

Key features

  • -4 AN ORB male with FKM (Viton) O-ring.
  • Multi-barb for 10 mm (3/8") nylon fuel tube.
  • E85 compatible.
  • 6061-T6 aluminum, black anodized.
Sealing

The ORB end seals on its FKM (Viton) O-ring against the port face; do not use tape or sealant on it. Secure the tube on the barb with an Oetiker ear clamp.
