Banjo Fittings

Q: What are banjo fittings used for?

Banjo fittings redirect a fluid line through a compact connection, making them useful when a straight fitting would interfere with nearby components or force a sharp hose bend. Evil Energy options cover brake, clutch, fuel, hydraulic, and power steering applications when the selected fitting specifications match the system.

Q: How do I choose the right banjo adapter size?

Match every interface separately. For the Evil Energy 3AN banjo adapter , verify the 3AN 3/8‑24 UNF hose connection , choose a 10.2mm or 12.2mm banjo bore , and select straight, 45°, or 90° routing. For a metric banjo bolt , match M10 or M12 diameter, the exact thread pitch, and the listed bolt length. Do not choose only by the vehicle model or the approximate diameter.

Q: Are Evil Energy banjo fittings suitable for brake, fuel and oil systems?

The 303 stainless steel 3AN banjo fitting is listed for brake, clutch, fuel, hydraulic, and power steering systems. Its published specifications include a 1,500 PSI working pressure and a −63°F to 252°F temperature range . The metric stainless steel banjo bolt listing includes fuel, oil, brake fluid, unleaded gasoline, methanol, and water. The complete assembly must still meet the pressure, temperature, fluid, and vehicle requirements of the specific application.

Q: Do banjo fittings restrict fuel or oil flow?

A banjo fitting changes the flow path around a hollow bolt, so restriction depends on the smallest internal passage and the system’s required flow. A pressure rating does not establish flow capacity. For high flow fuel or oil applications, compare the complete flow path rather than choosing solely from the AN size or pressure rating. If unrestricted flow is a critical design requirement, follow the system or component manufacturer’s specified connection.

Q: How do you stop a banjo fitting from leaking?

Start with the correct banjo bore, bolt diameter, thread pitch, bolt length, and sealing washers . Keep both sealing faces clean and undamaged, and use new, correctly sized crush washers wherever the system specifies them. Tighten to the vehicle or component manufacturer’s torque specification, then inspect and pressure test the completed connection before operation. Do not use thread sealant as a substitute for the specified crush washer or 37° AN flare seal . For U.S. road vehicle brake applications, brake hoses, assemblies, and end fittings fall within FMVSS No. 106 ; confirm the completed assembly and installation satisfy the applicable requirements.

Shop banjo fittings for compact brake, clutch, fuel, hydraulic, and power steering line routing. Evil Energy offers stainless steel metric banjo bolts and 3AN banjo adapters that help change the line exit direction where a straight connection may create clearance problems or unnecessary hose stress. Select by the connection on both sides, not by vehicle name or nominal diameter alone.

Match the Banjo Adapter to Both Sides of the Connection

For a hose connection, choose the 3AN banjo adapter with a 3AN 3/8‑24 UNF, 37° AN flare, then match the component side to a 10.2mm or 12.2mm banjo bore. Straight, 45°, and 90° options let you route the line according to available clearance. When replacing the hollow fastener, select the metric banjo bolt with two copper washers by M10 or M12 diameter, exact thread pitch, and listed length. Checking every dimension before ordering helps avoid cross threading, poor washer contact, and a forced hose angle.

Compact Banjo Fittings for Brake, Clutch and Fuel Routing

The Evil Energy 303 stainless steel 3AN banjo fitting is listed for brake, clutch, fuel, hydraulic, and power steering systems, with a published working pressure of 1,500 PSI and temperature range of −63°F to 252°F. The metric stainless steel banjo bolt listing covers fuel, oil, brake fluid, unleaded gasoline, methanol, and water. These low profile fittings are selection based components rather than universal fit parts, so confirm the port thread, banjo bore, angle, fluid, and complete system requirements before purchase. For additional routing components, browse Evil Energy AN fittings and adapters.
