Sapphire water jet nozzle with excellent cost performance and super high pressure

Excellent cost performance and super high pressure

Super high pressure Water Jet is used for variety of occasions like washing, exfoliation/chipping of concrete, deflashing resin, cutting paper, etc.

OGURA has developed “Sapphire Water Jet nozzle” and providing it to the market. The “Sapphire water jet nozzle” has excellent direct injection feature with outstanding cost performance.

Sapphire is adopted for a tip of nozzle with enough pressure and abrasion resistance.

Basic shapes

Sapphire water Jet Nozzle

Sapphire water Jet Nozzle


  • Higher cost performance compared with diamond.

  • A large destructive power can be expected by concentrating energy by extra fine jet stream.

  • With the excellence in straightness, suitable for sharpshooting for deburring from IC mold resin.

  • Nozzle chip is fixed with metal assembled and has a higher corrosion residence than sintered nozzle.
