1/8 MPT Pipe Nipple Black

The 1/8 MPT Pipe Nipple Black is a compact straight adapter fitting designed for fluid and pneumatic systems requiring secure, leak-free connections. Built by FRAGOLA, a trusted name in performance fluid transfer components, this nipple serves technicians, mechanics, and fabricators who need reliable inline adapters for fuel lines, air lines, and hydraulic circuits. The straight configuration eliminates unnecessary angles, preserving flow efficiency and reducing installation complexity in tight engine bays and equipment enclosures.

Manufactured from aluminum and finished in black anodized coating, this fitting combines durability with corrosion resistance. The 1/8 inch NPT (National Pipe Thread) male-to-male configuration on both ends ensures compatibility with standard industrial and automotive plumbing systems. Anodized aluminum provides lightweight construction—crucial in racing and off-road applications—while the black finish delivers a professional appearance and protects against oxidation in harsh environments. The straight design minimizes dead-leg volume, critical for systems sensitive to fluid stagnation or contamination.

This nipple is ideal for custom fuel system builds, pneumatic tool manifolds, and hydraulic repair applications where NPT threaded connections are standard. The compact 1/8 inch size makes it perfect for precision applications requiring minimal flow restriction and tight spatial constraints. Installation is straightforward: apply thread sealant tape or pipe thread compound to both male ends, then torque into NPT female ports using a wrench. Commonly paired with fuel regulators, air filters, and manifold blocks, this adapter ensures code-compliant, professional-grade connections that withstand vibration and pressure cycling.
