The Texas Speed 12AN Female to 3/4" Hard Tube Adapter Fitting connects a 3/4" outside-diameter hard line to a -12AN connection. The -12AN female end threads onto a -12AN male port or adapter, so the fitting can terminate a 3/4" hard line directly at a component, fuel rail or bulkhead. In this size, -12AN is a large line size typically used for oil cooler, dry sump scavenge, coolant and vent lines, and 3/4" is the matching nominal tube size for -12AN.
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 12AN female to 3/4" hard tube adapter do?
It adapts a 3/4" outside-diameter hard line, such as a factory steel or aluminum fuel or oil line, to a -12AN female connection. The -12AN female side connects to any standard -12AN male port, bulkhead or adapter fitting.
Is this 3/4" tube to 12AN 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 12AN female hard tube adapter made of?
The 12AN Female to 3/4" 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 12AN female to 3/4" hard tube adapter is not vehicle specific. It fits any 3/4" OD hard line and any standard -12AN male fitting.
What AN size matches a 3/4" hard line?
Texas Speed pairs 3/4" tube with -12AN on this adapter. The AN dash size is based on the nominal tube outside diameter in sixteenths of an inch, so a -12AN fitting is the standard match for 3/4" OD tubing.
