The Texas Speed 8AN Male to 1/2" Hard Tube Adapter Fitting connects a 1/2" outside-diameter hard line to a -8AN connection. The -8AN male end accepts a standard -8AN female hose end, so the fitting is a clean way to transition from a 1/2" hard line to AN braided hose. In this size, -8AN is a common size for higher-flow fuel feed lines, oil cooler lines and remote filter plumbing, and 1/2" is the matching nominal tube size for -8AN.
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 8AN male to 1/2" hard tube adapter do?
It adapts a 1/2" outside-diameter hard line, such as a factory steel or aluminum fuel or oil line, to a -8AN male connection. The -8AN male side connects to any standard -8AN female hose end or adapter.
Is this 1/2" tube to 8AN 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 8AN male hard tube adapter made of?
The 8AN Male to 1/2" 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 8AN male to 1/2" hard tube adapter is not vehicle specific. It fits any 1/2" OD hard line and any standard -8AN female fitting.
What AN size matches a 1/2" hard line?
Texas Speed pairs 1/2" tube with -8AN on this adapter. The AN dash size is based on the nominal tube outside diameter in sixteenths of an inch, so a -8AN fitting is the standard match for 1/2" OD tubing.
