The Texas Speed -12AN ORB Port Plug seals an unused -12AN O-ring boss (ORB) port and ships with its O-ring installed, so it is ready to thread into -12AN O-ring boss ports such as unused ports on oil pans, remote oil filter mounts, fuel cells and surge tanks. An ORB plug seals on the O-ring at the face of the port rather than on a flare, which makes it the correct plug for straight-thread O-ring boss ports and distinguishes it from a flare cap or plug.
Texas Speed machines its caps and plugs from 6061 aluminum to tight tolerances and finishes them in black anodizing for corrosion resistance. The plugs are light, durable and compatible with most fuels, solvents and oils, and they keep contaminants out of an open port while preventing leaks.

FAQ
What is the Texas Speed -12AN ORB port plug used for?
It seals an unused -12AN O-ring boss (ORB) port, such as an open port on a fuel rail, regulator, filter, oil adapter or tank. The O-ring on the plug seals against the face of the port so the port stays leak free and closed off to dirt.
What is the difference between an ORB plug and a flare plug?
An ORB plug has straight threads and seals with an O-ring at the port face, while an AN flare plug seals on a 37 degree flare inside a female AN fitting. This Texas Speed -12AN plug is an ORB plug, so it is meant for -12AN O-ring boss ports, not for capping a -12AN hose end or flare fitting.
Is the O-ring included with the plug?
Yes. The Texas Speed -12AN ORB port plug ships with its O-ring, so no separate seal is needed for installation in a standard -12AN O-ring boss port.
Is this plug safe for gasoline, E85 and oil?
Yes. Texas Speed states its caps and plugs are compatible with most fuels, solvents and oils, and the black anodized 6061 aluminum body resists corrosion in fuel and oil system use.
Is this a universal part?
Yes. The -12AN ORB port plug is not vehicle specific. It fits any standard -12AN O-ring boss port regardless of the vehicle or component it is installed on. Texas Speed also offers this plug in -TSP-3036AN, -TSP-4042AN, -TSP-6054AN and -TSP-8047AN sizes.
