10 mm Banjo Hose Barb Bolt Kit

This kit supplies two complete banjo hose barb bolt assemblies for brake, air, or fuel delivery systems. Each fitting is CNC-machined from metal for precise thread engagement and long-term sealing performance. The 10 mm internal diameter and 9 mm barb outside diameter suit a range of motorcycle and automotive plumbing tasks. Builders replacing worn banjo connections will find the hardware ready for direct installation.

Sustained pressure and vibration resistance

CNC machining keeps thread tolerances tight so the M10 × 1 bolt maintains clamp load under continuous brake-line pressure and engine vibration. Copper spacers deform evenly to seal the banjo face without extruding, preventing weep that can develop after repeated heat cycles. The barb profile grips hose securely, reducing the chance of blow-off during prolonged high-flow operation. No protective coating is mentioned, so corrosion resistance depends on the base metal and fluid compatibility.

Verify thread pitch and hose ID before ordering

Confirm that the existing banjo port uses an M10 × 1 thread pitch; other pitches will not seal with the supplied bolt. Measure the hose inner diameter to ensure it matches the 9 mm barb for a secure friction fit. Check that the 10 mm banjo internal diameter aligns with the fluid passage in the caliper, master cylinder, or distribution block you are connecting. The kit includes only the fittings, bolts, and four copper spacers — no hose, brake fluid, or tools are provided.

Questions about this item

Does the 10 mm banjo bolt generate noticeable heat or vibration during extended brake-system use?

The CNC-machined M10 × 1 bolt and copper spacers are designed for brake-system duty, so heat and vibration remain low under normal operation.

Which hose size and tools are needed to install these 9 mm barb fittings?

Use hose with a 9 mm inside diameter and secure it with standard clamps; a 10 mm spanner fits the hex head.

Will the 10 mm banjo thread and .39 inch internal diameter match the brake calipers on an older motorcycle?

The M10 × 1 thread and .39 inch banjo bore fit many vintage calipers that use the same metric specification.
