What materials is the Incure Sniper™ SN-18 optimised for?

The Incure Sniper™ SN-18 is optimised for low-viscosity UV adhesives (under 1,000 cP), cyanoacrylates, aqueous sealants, and thin coatings where maximum flow rate and minimal pump pressure are the priority. Its 1.039 mm ID is the largest bore in the Sniper™ range, making it the right choice when narrower gauges cause excessive backpressure on low-viscosity materials.

Why is non-magnetic phosphor bronze important for dispensing needles?

Steel dispensing needles can shed ferrous particles during use. These contaminate magnetic sensors, hard-disk read/write assemblies, MRI-compatible medical devices, and precision optical alignment components. Incure Sniper™ SN-18 is machined from phosphor bronze — non-magnetic and non-ferrous — so no ferrous particle contamination occurs during the dispensing process. This eliminates the need for a magnetic particle sweep between dispensing operations on sensitive assemblies.

Which coating should I choose for the SN-18?

Five coatings are available for the Incure Sniper™ SN-18: No Coating (bare cannula, standard option); Electroless Nickel (corrosion resistance, harder tip); Nickel PTFE (low-friction release layer for high-tack materials); Nickel Polymer Type SLK (more conformal than Nickel PTFE — superior release on tacky and filled adhesives); and Parylene Type C (vapour-deposited, pinhole-free — contact Incure for availability). The SN-18 is also available in Nickel Silver for applications requiring non-ferrous dual-material flexibility.

Is the SN-18 compatible with my dispensing barrel?

The Incure Sniper™ SN-18 uses a standard PP Luer Lock hub — compatible with any 1cc to 30cc Luer Lock dispensing barrel without adapters or proprietary connectors. The pink hub colour is the industry-standard visual code for this bore size, allowing rapid identification during line changeovers when multiple gauges are in use.

When should I choose SN-18 vs a finer gauge like SN-21?

Choose the Incure Sniper™ SN-18 when your process requires maximum flow rate at low pump pressure — typically for low-viscosity UV adhesives under 1,000 cP, aqueous fluids, or thin coatings where bead width tolerance is wider. Choose a finer gauge (SN-21 at 0.610 mm ID and below) when precision placement or narrow bead width is the priority, or when your adhesive viscosity is in the 1,000–10,000 cP range that benefits from a smaller opening for controlled flow.

SN-18 Phosphor Bronze Dispensing Needle — Incure Sniper™

Name: Incure Sniper™ SN-18 Phosphor Bronze Dispensing Needle
Brand: Incure Sniper™

Incure Sniper™ SN-18 is the widest bore in the range — 1.039 mm ID for low-viscosity UV adhesives, sealants, and aqueous fluids where maximum flow rate and minimal pump pressure are the priority. Where S19 through S30 gauges target progressively finer placement, the S18 delivers the highest volume per stroke at the lowest driving pressure. Non-magnetic phosphor bronze construction eliminates ferrous contamination on sensitive assemblies; the pink PP Luer Lock hub fits any standard dispensing barrel without adapters.

Largest Bore in the Sniper™ Range — Maximum Flow at Minimum Pump Pressure

At 1.039 mm ID, the SN-18 delivers the highest flow rate and lowest backpressure of any gauge in the Sniper™ range. Low-viscosity UV adhesives, cyanoacrylates, aqueous sealants, and thin coatings flow freely through the S18 bore without the pressure spikes that build in narrower gauges. If your system is running at elevated pump pressure with a finer gauge on a thin material, the SN-18 resolves the restriction by opening the flow path to its maximum.

Non-Magnetic Phosphor Bronze — No Ferrous Contamination on Sensitive Assemblies

Steel dispensing needles shed ferrous particles that contaminate magnetic sensors, HDD read/write assemblies, and precision optical alignment components. The SN-18 is machined from phosphor bronze — non-magnetic, non-ferrous, and chemically inert to UV adhesives, cyanoacrylates, and the solvents used in electronics and medical device manufacturing. No magnetic particle sweep is required between dispensing operations.

PP Luer Lock Hub — Fits Any Standard 1cc to 30cc Dispensing Barrel

The pink polypropylene Luer Lock hub seats directly on any standard 1cc to 30cc dispensing barrel — no adapters, no proprietary connectors, no tools required. Pink is the industry-standard colour code for this bore size; it allows immediate gauge identification during line changeovers when multiple Sniper™ gauges are in use, without reading a label or measuring the tip.
