Russell Performance 3/8in Allen Socket Pipe Plug (Endura)

Russell is known for making a wide variety of adapter fittings that let you connect their hose ends and hardlines to almost any system. This 3/8 inch Allen Socket Pipe Plug is a good example of their attention to detail. It's precision machined from 6061-T6 aluminum, which keeps it lightweight, and it comes with a durable Endura finish that looks good and helps prevent corrosion.

This plug is designed to create a positive seal, even at maximum operating pressures, so you can be confident it won't leak. It uses a 3/8 inch pipe thread size and has an internal wrenching plug design, meaning you'll use a 1/8 inch Allen socket to install it. This fitting is a solid option for sealing off unused ports in your fuel system, oil system, or other fluid lines.
