When building custom brake systems, hydraulic clutches, or turbo oil feed lines, relying on old rubber hoses or trying to assemble high-pressure PTFE lines from scratch can lead to disastrous leaks. The Fragola 10-inch Pre-Assembled -4 AN Hose eliminates the guesswork and the bleeding knuckles.
Manufactured in the USA, this line comes factory-crimped with straight -4 AN female swivel fittings on both ends. Because it features a true PTFE (Teflon) core wrapped in a stainless steel braid, it delivers a rock-solid pedal feel and handles virtually any automotive fluid without swelling, degrading, or bursting under extreme racing conditions.
Key Features
-
Factory-Crimped Ends: The straight -4 AN swivel fittings are machine-swedged at the Fragola facility. This guarantees a leak-proof seal that holds up to extreme hydraulic pressures much better than DIY reusable hose ends.
-
PTFE (Teflon) Core: Highly resistant to all harsh automotive chemicals, including DOT 3/4/5 brake fluid, synthetic oils, E85, and nitrous oxide. Unlike rubber, PTFE will not expand under pressure, ensuring immediate brake or clutch response.
-
Stainless Steel Braiding: The tough stainless outer jacket protects the inner core from abrasion, flying track debris, and extreme exhaust heat.
-
Universal -4 AN Sizing: A highly versatile size used heavily in drag racing, circle track, and custom street builds for fluid transfer.
