Russell Performance 1/2in Allen Socket Pipe Plug (Black)

This is a 1/2 inch Allen socket pipe plug from Russell Performance, finished in black. It's designed to seal off threaded ports in your fuel system, oil system, or other fluid lines. When you're running braided or hard lines, you'll often need to plug unused fittings or ports, and this plug does the job reliably.

It's precision machined from 6061-T6 aluminum, which keeps it lightweight while still offering a strong, positive seal even at maximum operating pressures. The black anodized finish helps it blend in with other black components in your engine bay, offering a clean look. This plug uses a 1/2 inch NPT thread size and requires an Allen wrench for installation.
