#4 Str TFE Hose End

The #4 Str TFE Hose End from XRP-XTREME RACING PROD. is a precision straight hose fitting designed for high-performance fuel, oil, and coolant systems in modified vehicles and racing applications. Built for mechanics and enthusiasts who demand reliability under pressure, this adapter connects 4 AN PTFE hose to 4 AN female ports with zero leakage tolerance. Whether you're tuning a street rod, upgrading a track car's fuel delivery, or rebuilding a custom cooling circuit, this fitting ensures your system flows at full capacity without compromise.

Machined from steel and finished in natural (bare) form, the #4 Str TFE Hose End features a straight (90°-free) configuration that minimizes turbulence and dead zones in fluid lines. The 4 AN sizing handles flows typical of LS-series engines, late-model V8s, and turbo applications without bottlenecking. PTFE (Teflon) hose compatibility means you're pairing this fitting with braided Teflon hose—the gold standard for heat resistance and fuel permeability barriers. The female port accepts standard AN male fittings, giving you flexibility in routing and component swaps during modifications or rebuilds.

Mechanics restoring fuel systems after carb-to-EFI conversions, engine swaps, or turbo installations will appreciate the straight geometry—it simplifies tight underhood packaging and reduces hose kinking in complex layouts. Each hose end is sold individually, so plan accordingly when routing multiple circuits. The compact 2.75-inch length and lightweight 0.1-pound design make it easy to integrate into OEM or custom chassis without adding bulk. For street, strip, or road-course duty, this XRP fitting delivers the durability and flow characteristics serious builders expect.
