The Texas Speed -4 ORB to -4AN Male Flare Adapter Fitting connects a -4 ORB (O-ring boss) port to a -4AN male flare so a -4AN hose end can be attached without any size change. ORB is the SAE straight-thread O-ring boss port style found on many fuel pumps, regulators, filters, pan and cooler adapters and billet accessories, and the flare side is a standard 37 degree AN male. In this size, -4AN is a small line size commonly used for gauge feeds, fuel pressure reference, boost reference and small oil or coolant lines. It is machined from 6061 aluminum and black anodized for corrosion resistance.
Texas Speed designs its adapter fittings to remove extra joints from a fuel or oil system, which cuts bulk in tight areas and lowers the cost of a plumbing job compared with stacking several fittings. Texas Speed states the adapters are compatible with most fuels, solvents and oils, so this fitting suits gasoline, E85, oil and coolant plumbing. It is sold individually.

FAQ
What does the Texas Speed -4 ORB to -4AN adapter fitting do?
It adapts a -4 ORB (O-ring boss) port to a -4AN male flare, so a -4AN hose end or AN fitting can be connected to a component that has a -4 ORB port, such as a fuel pump, regulator, filter or oil adapter.
What is the difference between ORB and AN threads on this fitting?
ORB is a straight-thread O-ring boss port that seals with an O-ring at the port face, while AN is a 37 degree flare that seals metal to metal against the hose end. This Texas Speed fitting has a -4 ORB side and a -4AN male flare side.
Is the Texas Speed -4 ORB to -4AN fitting safe for E85 and gasoline?
Yes. Texas Speed states its adapter fittings are compatible with most fuels, solvents and oils, and the black anodized 6061 aluminum body resists corrosion in fuel and oil systems.
What is this adapter fitting made of?
The Texas Speed -4 ORB to -4AN male flare adapter is machined from 6061 aluminum and finished in black anodizing, which keeps it lightweight and protects it from corrosion.
Is this a universal part?
Yes. The -4 ORB to -4AN adapter fitting is not vehicle specific. It fits any component with a -4 ORB port and accepts any standard -4AN female hose end or adapter.
