20G Blunt Tip Dispensing Needle with Luer Lock 1 inch 

Industrial Glue Dispensing Needle Blunt Tip 20G 1 inch tube

A 20G (20 gauge) dispensing needle with a 1-inch length and spiral lock is a specialized component for controlled application of adhesives and other fluids. The term "spiral lock" refers to the Luer-Lock design, which uses a threaded hub to create a secure, leak-proof connection to a syringe or other dispenser.

Key specifications

• 20 Gauge (20G): A standard indicator of the needle's diameter. A 20G needle has an inner diameter of 0.024 inches (0.6mm) and an outer diameter of about 0.035 inches (0.9mm).
• 1 inch (25.4mm): The length of the stainless steel cannula, the straight portion of the needle.
• Spiral Lock: Also known as Luer-Lock, this refers to the threaded plastic hub that attaches to the syringe. The threads ensure the needle doesn't pop off under pressure, preventing leaks.
• Blunt Tip: Most dispensing needles have a blunt end rather than a sharp point. This is for safety and to prevent scratching surfaces during application.
• Materials: Needles are typically made from stainless steel for durability and chemical resistance. The hub is usually a plastic such as polypropylene.
