Ruby & Sapphire Orifices

Most Common, Industry Standard Orifice

Rubies and sapphire orifices are basic consumable parts for waterjet cutting. They have a lifespan of around 20 to 40 hours depending on the type of application, environment and jet stream they are used in. Sapphire orifices deliver long, coherent jet streams, whereas ruby orifices are slightly more robust and deliver a shorter, more turbulent jet stream.

Size: 0.004''/0.10mm - 0.018''/0.45mm

Performance Advantages
  • Lifespan of around 20 to 40 cut hours   
  • Commonly used for non-critical applications
  • Average cutting speed, edge cut quality and durability.

Ruby/Sapphires Orifices



tetraCORE Orifices

More Cutting, Less Downtime


tetraCORETM orifices are the most cost effective orifice available. tetraCORETM orifices are manufactured under tightly controlled conditions and engineered to offer superior cutting performance for almost any waterjet cutting application.

Size: 0.004''/0.10mm - 0.018''/0.45mm

Performance Advantages
  • Lasts up to 15 times longer than ruby or sapphire orifices - Approximately 400 or more cut hours                               
  • Increases mixing tube life by up to 30%
  • Superior jet stream consistency
  • Fewer scrapped parts
  • Excelling reliability and efficiency
  • Reduces overall operating costs.

Diamond Orifices

Strongest, Hardest Waterjet Orifice


The diamond orifice range is the hardest, strongest orifice available in the industry. It has the longest lifespan of a minimum of 500 cut hours from waterjet use.

It enables water pressures up to 90,000 psi without signs of erosion or wear on the jewel. It is reliable and provides the cleanest, most precise cut when used with a Dimond Guard Filter on waterjet machines. 

Size: 0.004''/0.10mm - 0.018''/0.45mm

Performance Advantages
  • Lifespan of around 1,000 cut hours              
  • Hardest, most robust orifice
  • Maximum cutting precision and edge quality on applications
  • Superior cutting performance
  • Optimise jet stream length
  • Reduces overall operating costs.
