kennametal banana 40 degree curved nozzleThe Kennametal Banana is a boron carbide curved nozzle with a 40 arc through the nozzle body the entire metal jacketed body bends through 40 rather than using a deflector tip, delivering the blast stream along a smooth curve for reduced turbulence and wear at the direction change. With a 3 4" NPSM metal thread and four metric bore sizes from 6 mm to 12 mm, the Banana Series is the only nozzle in the Kennametal catalogue offered exclusively in metric

The Kennametal Banana is a boron carbide curved nozzle with a 40° arc through the nozzle body — the entire metal-jacketed body bends through 40° rather than using a deflector tip, delivering the blast stream along a smooth curve for reduced turbulence and wear at the direction change. With a 3/4" NPSM metal thread and four metric bore sizes from 6 mm to 12 mm, the Banana Series is the only nozzle in the Kennametal catalogue offered exclusively in metric bore diameters. Boron carbide provides typically five to ten times longer service life than tungsten carbide with aggressive abrasives such as aluminium oxide and selected mineral abrasives.

The curved body allows the blast stream to be redirected around obstructions or into recessed areas without positioning the entire blast nozzle assembly at an angle — the nozzle body itself carries the 40° change of direction. This makes the Banana Series suited to blast cabinets, spin blasters, and specialised industrial equipment where a curved nozzle entry is required to reach a target surface that cannot be blasted in a straight line. The metal jacket provides robust protection for the boron carbide liner in fixed and semi-fixed mounting applications.

The 3/4" NPSM thread connects the Banana nozzle to equipment with 3/4" nozzle holders. Kennametal offers boron-carbide-lined adapters — 50 mm to 3/4" NPSM and 1-1/4" NPSM to 3/4" NPSM — allowing the Banana Series to be connected to standard nozzle holders. Boron carbide is more brittle than tungsten carbide: careful handling during installation and removal is required, and rough handling should be avoided.

Key Features

• 40° curved body — smooth arc through the full nozzle body, not a tip deflector; reduces turbulence and wear at the direction change
  
• Recommended for aluminium oxide and selected mineral abrasives
• Metal jacket and metal threads
• 44.5 mm (1-3/4") OD body
  
• Thread: 3/4" NPSM (metal) — designed for 3/4" nozzle holders; requires adapter for standard 1-1/4" or 50 mm blast nozzle holders, adapters available separately.

Available Sizes & Lengths
Available in bore sizes 6 mm, 8 mm, 10 mm and 12 mm, all at a length of 117 mm.
