Syringe Tips with Luer Lock Connection

Tapered Tip

Dispense fluid from syringes and other small instruments with luer lock or luer slip connections. These tips are made of plastic, so they wont scratch parts while dispensing.

Tapered Tip—Tapered tips are a good alternative to needles when you need to reduce backpressure. They work best with medium- to high-viscosity materials. Trim tips without a resealable cap to the opening size you need.

Plastic Syringe Needles with Luer Lock Connection

Curve these plastic needles to reach into tight spots. They can be cut to the length you need. Unlike metal needles, they’re less likely to clog from instant-bonding adhesives and other sticky liquids. They also won’t scratch your surface when dispensing. Attach them to syringes with luer lock connections.

Static-Control Syringe Tips with Luer Lock Connection

Drain static from the material you’re dispensing from a syringe or other small instrument. These tips protect sensitive equipment from electrostatic discharge (ESD). This makes them ideal for applying adhesives to electronics. For a complete static-control syringe, you’ll need one with a static-control barrel. Twist these tips onto a syringe with a luer lock or luer slip connection.

These tips require less pressure on a syringe plunger when dispensing than syringes with a needle attached. Since they’re tapered, you can trim them to the opening size you need. They work best with medium- to high-viscosity materials—think the same viscosity as maple syrup or honey. Made of polypropylene plastic, these tips won’t scratch your equipment while in use.

Static-Control Syringe Needles with Luer Lock Connection

To protect sensitive equipment, these needles drain electrostatic discharge (ESD) from the materials they dispense. That means they’re great for applying adhesives to electronics. For a complete static-control syringe, you’ll need one with a static-control barrel. Twist them onto a syringe with a luer lock or luer slip connection. With a flat tip, they’re good for most applications and dispense a flat, even bead of material.
