25G*32.5MM Medical Stainless Steel Single-hole Irrigation Dental Needle Tube ISO9626

Dental needle tubes are key metal part of dental needles and they are small-bore, thin-wall stainless steel needle tubes which are typically used for numbing an area before a procedure or removing plaque and tartar from teeth. The regular diameter sizes of dental needles are 25G, 27G and 30G, depending on their applications and patients. For irrigation usage, the dental needle tube’s tips are generally blunt, single-hole/double-hole, half-opened, or sealed. The single or dual distal holes are used for controlled fluid delivery (like saline, antiseptics) during dental procedures, minimizing tissue trauma while ensuring consistent fluid flow. And for anesthesia usage, the dental needles are used as injection needles, so the needle tips are lancet bevel tips. Due to the good resistant to corrosion and good durability, dental needle tubes are mainly manufactured by medical stainless steel 304 material grade.

Our company can design different types of medical dental needle tubes with different needle tips based on clients’ drawings or samples. And our dental needle tubes are complied with ISO9626:2016 international standard to ensure the dimensional tolerance, good surface finish, cleanliness. In addition to dental needle tubes, we can also provide hypodermic needle tubes, insulin needle tubes, blood collection needle tubes, blood lancet, AV fistula Needle tubes, and so on. These stainless steel needle tubes serve as the core component of many kinds of medical needles, engineered for biocompatibility, corrosion resistance, and mechanical stability.

Key Features:

• SUS304 stainless steel material: Good corrosion-resistant, non-magnetic, and biocompatible
• Single-Hole Needle Tip Design: Distal opening ensures precise, localized irrigation without side perforations. Single-hole design reduces risk of tissue injection or splattering compared with multi-hole needles.
• Surface Finish: Smooth, burr-free interior/exterior (Ra ≤ 0.8 μm), preventing bacterial adhesion and ensuring fluid flow consistency.
• High Tensile Strength and Good Rigidity.
• Freedom From Surface Defects (E.g., Scratches, Pits)

Applications Of Dental Needles:

• Dental Irrigation: To deliver coolant or antiseptic during the endodontic (root canal) therapy.
• Periodontal Cleaning: To remove subgingival plaque in periodontal pockets.
• Surgical Rinsing: To flushing debris during oral surgery or implant placement.
• Compatible Devices: dental syringes, handheld irrigators.
