Chem-Set 103N Needle Extension Hot Melt Nozzle

Description

103N needle nozzle is a Chem-Set hot melt glue gun accessory for placing adhesive in tight spots where a standard cap nozzle is too broad. The needle extension format helps operators reach small joints, corners, fixtures, and repair areas while keeping bead placement under control.

103N needle nozzle Benefits

• Narrow extension tip supports more accurate hot melt placement in small bond areas.
• Accessory format lets crews adapt compatible glue guns to detail work without changing adhesive sticks.
• Works well for dots, short beads, tack points, and small repairs where a wide bead wastes material.
• Small spare part is easy to stock at packaging, display, woodworking, and repair benches.
• Use with the matching check valve assembly when the gun setup requires that valve body.

This nozzle is useful when hot melt needs to land inside a channel, around a bracket, near a fixture edge, or on a narrow strip. Keep it with compatible guns, check valves, and glue sticks so the operator can switch tip style before the job starts.

103N needle nozzle Applications

• Applying hot melt dots in packaging and carton repair work.
• Placing adhesive in display, sign, and light assembly fixtures.
• Reaching small woodworking joints, jigs, and edge details.
• Adding tack points before clamps, screws, or final adhesive cure.
• Replacing clogged or worn detail nozzles on compatible hot melt stations.

Setup And Use Guidance

Warm the glue gun fully before removing or installing the nozzle. A cold connection can hold cured adhesive in the threads and may damage the gun if forced. Wear heat-resistant protection and keep hands clear of the outlet while changing tips.

After installation, purge a small bead through the nozzle before production use. If flow slows, check for cooled adhesive at the extension before increasing trigger force. Keep the tip clean between uses so the next bead starts predictably.

Technical Details And Documentation

Current accessory references describe a needle extension nozzle for Pro Series style hot melt glue guns and note that the matching check valve assembly is sold separately. For broader hot melt adhesive guidance, review the Adhesive and Sealant Council.
