1/4 HOSE BARB X 1/8 MPT Fitting

The 1/4 hose barb x 1/8 MPT fitting from FRAGOLA is a precision adapter engineered for fluid transfer systems where reliable connections between hose and threaded port fittings are essential. This straight-passage connector bridges 1/4-inch hose barb inlets to 1/8-inch male pipe thread (NPT) ports, making it ideal for fuel systems, coolant loops, hydraulic applications, and custom plumbing in automotive, marine, and industrial equipment. Whether you're building or repairing a high-performance fuel line, intercooler circuit, or pressurized cooling system, this fitting provides the secure, leak-resistant joint that mission-critical installations demand.

Constructed from aluminum and finished in blue anodized coating, this fitting combines lightweight durability with corrosion resistance—critical for longevity in engine bays and exposed environments. The hose barb design grips tubing securely when paired with hose clamps, creating a mechanical lock that withstands vibration and pressure cycling without slipping. The 1/8 NPT male thread cuts cleanly into female receiver ports with standard pipe-thread sealant (PTFE tape or thread compound), establishing a metal-to-metal seal that holds across temperature extremes and pressure fluctuations common in automotive and industrial duty cycles.

This adapter suits technicians, fabricators, and enthusiasts upgrading or repairing fluid systems on street rods, race vehicles, marine engines, and industrial machinery. Installation is straightforward: fit 1/4-inch hose over the barb (typically with two hose clamps for security), screw the MPT end into a 1/8 NPT female port using appropriate thread sealant, and tighten to hand-snug plus a quarter turn. Verify hose ID compatibility (typically 3/8-inch OD hose) and confirm NPT receiver threads before ordering. FRAGOLA's reputation for precision fitting manufacture ensures dimensional accuracy and reliable performance across thousands of installations.
