Speedmaster PCE331.1039 Internal Allen Head Pipe Plug NPT Black Anodized - 1/8

The Speedmaster PCE331.1039 is a precision-machined internal Allen head pipe plug designed to seal unused 1/8" NPT threaded ports on your engine or chassis components. Featuring a black anodized aluminum finish, this plug provides both corrosion resistance and a clean, professional appearance under the hood.

Key Features:

• 1/8" NPT male thread for secure, leak-free sealing
• Internal hex socket design allows installation with a standard Allen wrench
• Black anodized aluminum construction resists corrosion and wear
• Low-profile design maintains a clean appearance
• Ideal for sealing unused ports on intake manifolds, nitrous systems, oil pans, and fuel systems

This plug is perfect for applications where you need to close off unused threaded ports during engine builds, modifications, or when removing components like nitrous oxide systems, vacuum lines, or fluid passages. The internal hex design keeps the exterior profile low and unobtrusive, while the anodized finish complements most engine bay aesthetics.
