Earl's Performance Banjo Bolt and Fitting
Earl's Performance Banjo Bolts & Fittings: Precision Where It Counts
When fluid connections need to change direction in tight quarters — at brake calipers, carburetor fuel inlets, or power steering ports — a banjo bolt and fitting is the engineering solution of choice. Earl's Performance has been perfecting these components for decades, and their banjo bolt and fitting lineup reflects the same obsessive attention to material quality and dimensional accuracy that has made the brand a cornerstone of motorsports plumbing worldwide.
A Legacy of Plumbing Innovation
Earl's Performance was founded in 1955, originally supplying high-quality military aircraft surplus plumbing components to the racing industry. As that surplus market dried up, the company pioneered its own range of hoses and fittings — products that are still trusted by racers and builders today. That same spirit of precision engineering carries directly into their banjo bolt and fitting category, where correct fitment and leak-free sealing are non-negotiable.
What Earl's Performance Offers in Banjo Bolts & Fittings
Earl's banjo bolt and fitting selection spans a broad range of materials, thread sizes, and applications. Whether you're connecting a brake line to a caliper, routing fuel to a carburetor, or adapting a power steering line, the lineup has a configuration to match:
- Stainless Steel Banjo Bolts: Replacement fuel banjo bolts in stainless steel, such as the 9/16"-24 thread version, are compatible with Holley Carter AFB and AVS, Demon Race, Speed and Road, and Edelbrock Performer Square Flange carburetors — making them a natural choice for classic and competition builds.
- 10mm Banjo Bolts (Coarse & Fine): Available in both coarse and fine thread pitches, these bolts cover a wide range of OEM-style brake and fuel system connection points where metric hardware is required.
- Banjo Adapters — Long Style: Earl's long-style banjo adapters feature a -3 AN male straight non-adjustable design for 3/8" or 10mm banjo bores, bridging the gap between AN plumbing and banjo-style connections with clean, professional results.
- Brake System Banjo Adapters: Designed to interface with Earl's HYPERFIRM brake hose system, these adapters connect the high-pressure hose to the stock brake wheel cylinder or caliper and are offered in multiple configurations to cover different vehicle applications. Electroless nickel-plated short steel versions in -3AN to 3/8"-24 inverted flare are available, as are blue anodized lightweight aluminum versions for builders who want a polished look under the hood.
- Speed-Seal Compatible Banjo Bolts: For builders using Earl's Speed-Seal hose ends with PTFE-lined stainless braid hose, dedicated steel banjo bolts with a .425 in. banjo height and .375 in. (10mm) diameter are available in straight, non-adjustable long configurations.
- Crush Washers: Earl's rounds out the category with AN 901 aluminum crush washers and copper crush washers in multiple fitting sizes, ensuring a proper leak-free seal at every banjo joint.
Why Choose Earl's for Banjo Bolts & Fittings?
Unlike generic hardware-store fasteners, Earl's banjo bolts are engineered specifically for automotive fluid systems, where pressure, vibration, and heat cycling demand materials and tolerances that go well beyond standard. The variety of finishes — natural stainless, electroless nickel, and anodized aluminum — means builders can match the hardware to the system's requirements, whether that's corrosion resistance in a brake line or lightweight construction in a race application. With roughly 30 distinct part numbers in this category, Earl's covers both direct OEM-replacement scenarios and custom performance builds.
