The Texas Speed 12AN Male to 24mm x 1.5 Metric Male Adapter Fitting joins a -12AN female hose end or adapter to a 24mm x 1.5 metric male thread, so a -12AN braided line can be run directly to a metric-threaded component without a second fitting in between. In this size, -12AN is a large line size used for oil supply and return lines, remote oil filter and cooler plumbing, dry sump systems and high-volume fuel or coolant lines. The metric end is a 24mm diameter thread with a 1.5mm pitch, which should be matched to the port or component it will thread into before ordering.
The fitting is machined from 6061 aluminum and black anodized, which keeps weight down and protects the body from corrosion. Texas Speed designs its adapter fittings to take the place of two separate fittings, which trims bulk in tight spaces and lowers the cost of a plumbing job. Texas Speed rates these adapters as compatible with most fuels, solvents and oils.

FAQ
What does the Texas Speed 12AN to 24mm x 1.5 metric adapter fitting do?
It adapts a 24mm x 1.5 metric male thread to a -12AN male flare, so a -12AN female hose end or AN adapter can connect to a component or port that uses 24mm x 1.5 metric threads. This Texas Speed adapter fitting replaces two separate fittings with one piece.
How do I know if 24mm x 1.5 is the right metric thread for my application?
Measure the thread on the mating part: the major diameter should be 24mm and the thread pitch 1.5mm (the distance between thread peaks). Texas Speed offers this -12AN adapter in several metric sizes, so confirm both the diameter and the pitch before ordering the 24mm x 1.5 version.
Is the Texas Speed 12AN to 24mm x 1.5 adapter safe for fuel and E85?
Texas Speed states that its adapter fittings are compatible with most fuels, solvents and oils. The black anodized 6061 aluminum body resists corrosion in fuel, oil and coolant plumbing.
What is the Texas Speed 12AN to 24mm x 1.5 metric adapter made of?
The fitting is machined from 6061 aluminum and finished in black anodizing. Texas Speed builds its adapter fittings to be lightweight and durable while reducing the number of joints in a line.
Is this a universal part?
Yes. The Texas Speed 12AN male to 24mm x 1.5 metric male adapter is not vehicle specific. It fits any -12AN female hose end or adapter and any port or component with a 24mm x 1.5 metric female thread.
