When should I choose the SN-20 over the SN-19?

Choose the Incure Sniper™ SN-20 when your adhesive is in the medium-viscosity range (1,000–10,000 cP) — UV adhesives with fillers, light one-part epoxies, or thickened formulations. The SN-19 (0.859 mm ID) is for low-viscosity materials under 1,000 cP. Using a wide-bore gauge like S19 on a medium-viscosity adhesive produces an over-wide, poorly controlled bead. The SN-20's 0.681 mm ID gives consistent flow and clean break-off at the pressures needed for thicker materials.

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

Steel dispensing needles can shed ferrous particles during use, contaminating magnetic sensors, hard-disk read/write assemblies, MRI-compatible medical devices, and precision optical alignment components. Incure Sniper™ SN-20 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 operations on sensitive assemblies.

Which coating should I choose for the SN-20?

No Coating is the standard bare phosphor bronze option — suitable for most UV adhesive and light epoxy dispensing. Electroless Nickel adds corrosion resistance and a harder tip surface, extending needle life in aggressive chemical environments or when dispensing filled formulations with abrasive particles. Nickel PTFE applies a low-friction release layer to the bore and tip face, reducing adhesive adhesion and residue build-up on the tip — particularly effective for medium-viscosity formulations that tend to string or leave a meniscus after dispensing. All three coatings are available across the full Sniper™ range.

Is the SN-20 compatible with my dispensing barrel?

The Incure Sniper™ SN-20 uses a standard PP Luer Lock hub — compatible with any 1cc to 30cc Luer Lock dispensing barrel without adapters or proprietary connectors. The green hub colour is the industry-standard visual code for this bore size, allowing rapid identification during line changeovers when multiple Sniper™ gauges are in use.

SN-20 Phosphor Bronze Dispensing Needle — Incure Sniper™

Name: Incure Sniper™ SN-20 Phosphor Bronze Dispensing Needle
Brand: Incure Sniper™

Incure Sniper™ SN-20 is the first gauge optimised for medium-viscosity adhesives — 0.681 mm ID for UV adhesives, light epoxy formulations, and thickened cyanoacrylates in the 1,000–10,000 cP range where the SN-18 and SN-19 bores are too wide for controlled placement and finer gauges create unnecessary backpressure. The SN-20 sits at the entry point of the medium-viscosity range, delivering consistent bead lines and clean break-off at the dispense pressures these materials require. Non-magnetic phosphor bronze construction eliminates ferrous contamination on sensitive assemblies; the green PP Luer Lock hub fits any standard dispensing barrel.

First Gauge Into the Medium-Viscosity Range — Where S18 and S19 Are Too Wide

At 0.681 mm ID, the SN-20 is the first gauge in the Sniper™ range to deliver controlled flow on medium-viscosity UV adhesives and epoxy formulations (1,000–10,000 cP). The wider S18 and S19 bores over-fill compact bond pads and lose bead control on thicker materials. The SN-20 gives the right opening for this viscosity band — consistent volume per stroke, clean thread break-off after retract, and placement precision that wider gauges cannot hold on medium-viscosity adhesives.

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-20 is machined from phosphor bronze — non-magnetic, non-ferrous, and chemically inert to UV adhesives, epoxies, 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 green polypropylene Luer Lock hub seats directly on any standard 1cc to 30cc dispensing barrel — no adapters, no proprietary connectors, no tools required. Green 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.

The SN-20 is the entry-point medium-viscosity gauge in the Incure Sniper™ range. For low-viscosity materials (<1,000 cP), see SN-18 (1.039 mm ID) or SN-19 (0.859 mm ID). For tighter placement at medium viscosity, see SN-21 (0.610 mm ID). For high-viscosity gels and filled formulations (>10,000 cP), see SN-23 (0.564 mm ID), SN-25 (0.437 mm ID), SN-27 (0.335 mm ID), or SN-30 (0.234 mm ID). All Sniper™ needles are phosphor bronze with PP Luer Lock hub and are available in No Coating, Electroless Nickel, or Nickel PTFE — same three options across the full range.
