Syringe Tips with Luer Lock Connection

Tapered Tip

Curved 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.

Curved Tip—Curved tips dispense fluid in hard-to-reach areas.

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.
