Adapter Ftg Fem 1/8NPT to Female 3/16inv 4pk

The Adapter Ftg Fem 1/8NPT to Female 3/16inv 4pk by ALLSTAR PERFORMANCE is a critical component for fluid and pneumatic system plumbing in high-performance engine builds, fuel systems, and brake line installations. This four-pack adapter set solves a fundamental challenge faced by mechanics and engine builders: connecting components with mismatched port sizes without compromising system integrity or requiring custom fabrication. Whether you're upgrading a carburetor fuel supply, installing an aftermarket fuel pressure regulator, or modifying brake proportioning valve lines, these adapters provide a reliable, code-compliant connection solution.

Each adapter features a female 1/8 NPT (National Pipe Thread) inlet paired with a female 3/16 inverted flare outlet, allowing you to bridge two different thread standards and port configurations in a single fitting. The 1/8 NPT connection accommodates sensor ports and small-diameter pneumatic fittings common on fuel pressure gauges and distribution blocks, while the 3/16 inverted flare end accepts traditional automotive brake and fuel line tubing used in street rods, race engines, and restoration projects. ALLSTAR PERFORMANCE's precision machining ensures leak-free performance under both continuous and pulsating pressure cycles, critical when managing fuel systems running 8+ PSI or brake systems handling repeated hard pedal input.

Technicians and fabricators benefit most from the four-pack quantity, which covers typical multi-component fuel or brake system upgrades while providing spares for future modifications. Installation requires only standard wrenches and proper flare-nut technique—wrap threads with thread-sealing tape and torque inverted flare nuts to manufacturer specifications (typically 12–18 ft-lbs) to prevent overtightening. Compatible with any system using 1/8 NPT sensor ports and 3/16 inverted flare hard line, this adapter pack is indispensable for street performance builds, vintage restorations, and professional shop environments where port standardization is impossible.
