Steel Braided Gauge Line 24in

The LONGACRE Steel Braided Gauge Line 24in is a precision fluid-line assembly designed to connect mechanical pressure gauges to hydraulic or fuel systems. This stainless steel braided hose kit combines robust construction with field-proven reliability, making it an essential component for engine builders, race teams, and automotive technicians who demand accurate real-time pressure monitoring without compromising system integrity.

The 24-inch length accommodates flexible routing from engine bay or frame-mounted gauges to the monitored system without excess hose that invites kinks or damage. The 4 AN female connection mates directly to standard -4 AN fittings found on carburetors, fuel blocks, and oil system ports, while the 1/8 inch NPT male end threads into compatible gauge ports. PTFE (Teflon) core tubing provides excellent chemical resistance to fuel, oil, and coolant, while the braided stainless steel outer jacket resists abrasion, vibration damage, and corrosion—critical in high-vibration or marine environments. Fittings are pre-installed, eliminating the need for secondary assembly and reducing potential leak points.

This gauge line serves engine tuning, fuel system diagnostics, and hydraulic monitoring across drag racing, off-road vehicles, marine engines, and street performance builds. Whether monitoring oil pressure during a high-RPM dyno session or tracking fuel pressure on a carbureted street engine, this assembly delivers the durability and precision required to capture accurate data without system contamination or fitting failure. Weighing just 0.32 lbs, the compact profile fits tight engine compartments and bracket-mounted configurations typical of retrofit gauge installations.
