The Texas Speed 4AN Female to 1/4" Hard Tube Adapter Fitting connects a 1/4" outside-diameter hard line to a -4AN connection. The -4AN female end threads onto a -4AN male port or adapter, so the fitting can terminate a 1/4" hard line directly at a component, fuel rail or bulkhead. In this size, -4AN is a small line size commonly used for gauge feeds, fuel pressure reference lines, boost reference and small oil or coolant lines, and 1/4" is the matching nominal tube size for -4AN.
Texas Speed machines its adapter fittings from 6061 aluminum and black anodizes them for corrosion resistance, which keeps the fitting light and durable. Running hard line to AN with a single adapter removes an extra joint from the system, which saves room in tight areas and reduces the number of places a line can leak. Texas Speed rates these adapter fittings as compatible with most fuels, solvents and oils.

FAQ
What does the Texas Speed 4AN female to 1/4" hard tube adapter do?
It adapts a 1/4" outside-diameter hard line, such as a factory steel or aluminum fuel or oil line, to a -4AN female connection. The -4AN female side connects to any standard -4AN male port, bulkhead or adapter fitting.
Is this 1/4" tube to 4AN adapter safe for gasoline and E85?
Yes. Texas Speed states that its adapter fittings are compatible with most fuels, solvents and oils, and the black anodized 6061 aluminum body resists corrosion in fuel and oil service.
What is the Texas Speed 4AN female hard tube adapter made of?
The 4AN Female to 1/4" Hard Tube Adapter Fitting is machined from 6061 aluminum and finished in black anodizing, which keeps it lightweight while protecting the surface from corrosion.
Is this a universal part?
Yes. The Texas Speed 4AN female to 1/4" hard tube adapter is not vehicle specific. It fits any 1/4" OD hard line and any standard -4AN male fitting.
Does Texas Speed offer this 1/4" tube adapter with a male AN end?
Yes. Texas Speed sells the 1/4" hard tube adapter in -4AN with a female AN end (TSP-4018) and with a male AN end (TSP-4019). Choose the female version when the AN side needs to thread onto a male port or adapter, and the male version for the opposite connection.
