REDZ Precision Liner Cartridges

Redz Precision Cartridges are the latest development in the Redz lineup. These cartridges offer a more rigid, engineered design for artists who prefer precision without an integrated grip.

They differ from the original Redz cartridges in several key ways. First, the needle plunger is stabilized at two points — by a squared rear cap and an internal guide — giving the needle extra steadiness, especially in larger configurations. The needle itself uses a solid wire, which maintains sharpness longer than standard flex-wire designs.

For better durability, the tip and housing are made from engineering-grade polycarbonate (PC) — a hard, wear-resistant plastic that resists friction from the needle, reducing distortion or micro-tears over time. Inside, a soft silicone membrane (FDA-approved) is tuned for smooth movement while minimizing drag on wireless machines — a practical upgrade for battery-powered workflows.

Another detail that sets these cartridges apart is the angled needle positioning. The needle sits downward by design, ensuring better contact with the tip — improving ink flow and eliminating the need for artists to manually bend needle bars for better performance.

Key Points:

• Solid wire needles
  Provide long-lasting sharpness and consistent performance across all needle groupings.

• Durable polycarbonate tip and housing
  Made from high-strength engineered plastic to resist friction and wear from needle movement.

• Soft silicone membrane
  FDA-approved membrane designed for smooth needle motion and reduced battery strain — ideal for wireless machines.

• Dual stabilizer system
  Stabilized at two points: a squared rear cap and an internal guide keep the plunger steady and reduce needle wobble.

• Angled needle position
  The needle sits lower in the tip to improve ink flow — no manual bending required.
