22in #4 Line -4 Str/-4 Str

The ALLSTAR PERFORMANCE 22in #4 Line -4 Str/-4 Str brake hose is a purpose-built hydraulic line designed for custom automotive cooling and brake system installations where reliable fluid transfer under pressure is critical. This braided stainless steel hose with PTFE lining serves mechanics, fabricators, and performance enthusiasts building custom-routed brake systems, fuel delivery networks, and high-temperature hydraulic circuits. At 22 inches in length with dual 4 AN straight female fittings on both ends, it bridges components with precision fit and eliminates the need for bulky adapters in tight engine bays or fabricated chassis work.

The hose features a braided stainless steel outer jacket that resists corrosion, abrasion, and UV damage—essential for underbody routing or engine bay exposure. The internal PTFE (polytetrafluoroethylene) lining provides superior chemical resistance and maintains fluid integrity under thermal cycling, preventing degradation common in traditional rubber hoses. The dual 4 AN female straight fittings enable direct female-to-female connections, allowing you to mate this line with male-end components or use it as an intermediate segment in your brake or fuel system layout. The compact 0.2 lb weight and 22-inch length make it ideal for space-constrained applications where factory routing won't suffice or where a custom-fabricated suspension or brake upgrade demands repositioned hard-line connections.

This hose excels in street rod builds, custom chassis projects, and race-prepared vehicles where stock brake or fuel line locations conflict with engine modifications or frame changes. Mechanics and fabricators rely on it to bypass factory routing constraints without sacrificing performance or safety. Verify that your existing fittings and components accept 4 AN female connections; this hose pairs seamlessly with adapters, tee fittings, and valves carrying 4 AN male ends. Proper support clipping every 12–18 inches along the run prevents vibration-induced wear and ensures the hose remains clear of moving components and heat sources.
