Waterjet Orifice: What is, Which to Choose, How It Works

What is a waterjet orifice

The waterjet orifice is the core component that transforms high-pressure water into a focused, high-velocity cutting jet.

How a Waterjet Orifice Works

Pressurized water (typically up to 60,000 PSI) passes through the precisely drilled, ultra-smooth hole of the orifice. Its tight geometry accelerates the water and concentrates it into a narrow, coherent jet. This concentrated jet delivers extreme cutting power for pure water applications and also serves as the vacuum engine that draws abrasive into the stream in abrasive waterjet cutting.

A high-quality orifice ensures stable jet formation, minimal energy loss, consistent cutting performance, and longer service life under continuous high-pressure operation.

What can Win-Win Supply

Win-Win Waterjet is a professional manufacturer and supplier of high-precision waterjet orifices, serving industrial cutting customers worldwide. We focus on designing and producing reliable replacement orifices fully compatible with all top-tier waterjet system brands, including Flow, KMT, OMAX, Wardjet, Bystronic, and other mainstream equipment.

• Ruby Orifices
• Our standard ruby orifices offer excellent cost performance and long service life, making them the most widely used solution for general pure water cutting of foam, rubber, gasket, textile, and thin sheet materials. They ensure stable jet shape and high cutting accuracy with low replacement cost.
• Sapphire Orifices
• Sapphire orifices feature higher hardness and wear resistance compared with sapphire, suitable for continuous high-pressure operation and medium-load production environments. They provide extended working hours and reliable performance for businesses seeking improved durability without excessive cost.
• Diamond Orifices
• As our premium-grade solution, diamond orifices deliver the longest service life, extremely high wear resistance, and exceptional dimensional stability. Ideal for heavy-duty, 24/7 production, high-pressure systems, and long-term continuous cutting, they greatly reduce downtime and maintenance frequency.
