1/8in Pipe Plug

The EARLS 1/8in Pipe Plug is a precision aluminum fitting designed for applications in fuel systems, cooling circuits, and pneumatic lines where effective port sealing is essential. Automotive technicians will find this component invaluable for blocking off unused ports during various modifications, including custom fuel rail builds and turbo conversions.

Constructed from lightweight aluminum, the 1/8in Pipe Plug features a tapered male NPT (National Pipe Thread) design that ensures a leak-proof seal when installed in standard 1/8in female ports. The tapered thread geometry provides consistent clamping force, often eliminating the need for additional sealant, although many builders opt for thread-sealing compounds in high-pressure scenarios.

This compact fitting is particularly beneficial for tight engine bay installations, making it ideal for custom fuel system work, intercooler plumbing, and boost control circuits. Whether for professional engine builders or weekend enthusiasts, EARLS fittings are recognized for their reliable performance and dimensional accuracy.
