The Texas Speed -10 ORB Port Plug seals an unused -10 O-ring boss port on a fuel rail, oil pan, valve cover, pump or fitting block. It threads into the ORB port and seals on the included O-ring rather than on a flare or thread sealant, which gives a clean, reusable seal and keeps dirt out of the open port.
Texas Speed machines its caps and plugs from 6061 aluminum to tight tolerances and black anodizes them for corrosion resistance. The plug is lightweight, durable and compatible with most fuels, solvents and oils, so it suits fuel, oil and coolant plumbing on street and race builds.

FAQ
What is a -10 ORB port plug used for?
A -10 ORB port plug seals an unused -10 O-ring boss port, such as a spare port on a fuel rail, oil pan, valve cover or fitting block, using the O-ring on the plug instead of thread sealant.
Is the O-ring included with the Texas Speed -10 ORB plug?
Yes. The Texas Speed -10 ORB port plug ships with its O-ring installed so it is ready to seal an O-ring boss port out of the package.
Is this plug safe for gasoline, E85 and oil?
Texas Speed states its aluminum caps and plugs are compatible with most fuels, solvents and oils, and the black anodized 6061 aluminum resists corrosion.
Is this a universal part?
Yes. The -10 ORB port plug is not vehicle specific. It fits any standard -10 O-ring boss port on any vehicle or component.
