    The Texas Speed M10 x 1.25 Low Profile Metric Port Plug seals an unused M10 x 1.25 threaded port on a fuel rail, oil component, sensor boss or other metric-threaded fitting. Its low profile head sits close to the surface for tight clearance areas, and a sealing washer is included with the plug.

    Texas Speed machines its caps and plugs from 6061 aluminum to tight tolerances and black anodizes them for corrosion resistance. The plugs are compatible with most fuels, solvents and oils, and they prevent leaks while keeping dirt and debris out of open ports.

    FAQ

    What is the Texas Speed M10 x 1.25 low profile port plug used for?

    It seals an unused M10 x 1.25 metric threaded port, such as an open sensor or feed port on a fuel rail or oil component, with the included washer providing the seal.

    What is the difference between the M10 x 1.25 and M10 x 1.0 plugs?

    Both are 10 mm diameter plugs, but the thread pitch differs: 1.25 mm versus 1.0 mm. The plug must match the pitch of the port, so check the thread before ordering.

    What material is the port plug made from?

    Texas Speed machines the plug from 6061 aluminum and finishes it in black anodizing, which resists corrosion from fuel, oil and the elements.

    Can this plug be used in fuel and oil systems?

    Yes. Texas Speed states its caps and plugs are compatible with most fuels, solvents and oils, so the plug is suitable for fuel rail and oil system ports.

    Is this a universal part?

    Yes. The plug fits any M10 x 1.25 metric threaded port regardless of vehicle, so it is listed as a universal fitting rather than a vehicle-specific part.
