The Texas Speed 4AN Male to 1/4" Hard Tube Adapter Fitting connects a 1/4" outside-diameter hard line to a -4AN connection. The -4AN male end accepts a standard -4AN female hose end, so the fitting is a clean way to transition from a 1/4" hard line to AN braided hose. 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 male to 1/4" hard tube adapter do?

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 male hard tube adapter made of?
The 4AN Male 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?

Does Texas Speed offer this 1/4" tube adapter with a female AN end?
Yes. Texas Speed sells the 1/4" hard tube adapter in -4AN with a male AN end (TSP-4019) and with a female AN end (TSP-4018). Choose the male version when the AN side needs to accept a female hose end, and the female version for the opposite connection.
