Blunt Cannula
Blunt Cannulas for Dermal Filler Delivery: Wholesale Supply & OEM
AuroThread manufactures and supplies blunt tip cannulas and micro-cannulas in bulk for professional aesthetic clinics and medical distributors worldwide. Made from medical-grade 304 stainless steel with CE certification, our cannulas are available in a complete range of gauges (21G to 30G) and lengths (25mm to 50mm). Whether you need standard wholesale supply or full OEM private-label production, AuroThread delivers consistent quality at direct-factory pricing.
Cannula Gauge Selection Guide
Selecting the correct gauge depends on two factors: the viscosity of the filler being delivered and the delivery plane of the target zone. A higher gauge number equals a thinner outer diameter — finer gauges provide more precision for delicate zones, while lower gauges handle high-viscosity fillers for structural work.
| Gauge | Outer Diameter | Filler Compatibility | Recommended Zones |
|---|---|---|---|
| 21G | 0.81mm | High-density fillers, CAHA | Deep cheek, body contouring |
| 22G | 0.72mm | High-density HA, PLLA | Cheekbone, jawline, chin |
| 25G | 0.51mm | Standard cross-linked HA | Mid-face, temples, nasolabial folds |
| 27G | 0.41mm | Medium-viscosity HA | Nasolabial, marionette, forehead |
| 30G | 0.31mm | Fine HA, skin boosters | Tear trough, lips, peri-oral |
Cannula Length Options
| Length | Metric | Coverage From Single Entry Point | Best For |
|---|---|---|---|
| 1 inch | 25mm | Small, precise zones | Tear trough, lips, nasolabial folds |
| 1.5 inch | 38mm | Mid-size zones | Cheeks, jawline, temples (most versatile) |
| 2 inch | 50mm | Large surface areas | Full cheek, jawline contouring, body |
Korean Blunt Cannulas vs. Standard Cannulas
AuroThread supplies both standard blunt cannulas and premium Korean-manufactured cannulas. Korean cannulas feature Ultra-Thin Wall (UTW) technology for a wider inner diameter at the same gauge — reducing delivery pressure and improving filler flow for high-viscosity products. They also offer superior tip finishing through micro-polishing techniques, delivering a smoother glide through tissue with less drag. Both product lines carry CE certification and are manufactured under ISO 13485 quality standards. View Korean blunt cannula collection.

Frequently Asked Questions
Q: What material are your blunt cannulas made of?
Auro blunt cannulas are manufactured from medical-grade 304 stainless steel with an ultra-polished surface finish. The material meets biocompatibility standards and ensures smooth insertion with minimal tissue drag. Each cannula undergoes rigorous quality inspection for tip roundness, hub integrity, and side-port patency before sterilization and packaging.
Q: Which cannula gauge should I choose for different filler types?
For fine fillers and delicate zones (lips, tear trough, peri-oral): 27G or 30G cannulas provide maximum precision and minimal entry-point visibility. For standard HA fillers in mid-face and nasolabial folds: 25G offers the best balance of flow rate and control. For high-viscosity fillers and deep structural work (jawline, chin, cheekbone): 22G or 21G handles thicker product without excessive delivery pressure. Read our cannula introducer needle comparison.
Q: Does your cannula have a side-port marker?
Yes, all AuroThread blunt cannulas feature a clearly visible marker on the hub that indicates the direction of the side-port opening. This allows practitioners to control filler distribution with precision — directing product toward the desired plane and away from sensitive structures. The marker is embossed, not printed, so it remains visible throughout the session.
Q: How do you ensure the flexibility and durability of the cannula?
Our proprietary heat-treatment process achieves a calibrated balance of flexibility and stiffness. The cannula bends smoothly to navigate tissue planes without kinking or fracturing, yet retains enough rigidity to maintain directional control during fanning and retrograde delivery. Each production batch includes flexibility testing as part of our ISO 13485 quality protocol.
Q: Do you support OEM and private-label packaging for blunt cannulas?
Yes. AuroThread provides full OEM manufacturing for blunt cannulas across all gauges and lengths. Custom options include branded packaging design, logo printing on hubs and pouches, custom gauge and length specifications, and multi-language labeling. All OEM products carry the same CE Mark and ISO 13485 certifications. MOQ applies — contact us for details. Explore OEM cannula manufacturing.
Q: What is the difference between standard and Korean blunt cannulas?
Korean-manufactured cannulas use Ultra-Thin Wall (UTW) technology, providing a wider inner diameter at the same outer gauge — this reduces delivery force and improves flow for high-viscosity fillers. Korean cannulas also feature micro-polished tips for a smoother glide and tighter Luer-lock hub tolerances. Standard Auro cannulas offer excellent value for everyday applications. Both lines hold the same CE and ISO 13485 certifications. Browse Korean cannulas.
