Chem-Set 103R Round Extension Nozzle for Pro Series Glue Guns

Description

103R Extension Nozzle is the round-tip accessory for Chem-Set Pro Series hot melt glue guns when you need a narrower, more controlled adhesive bead than a standard wide nozzle. This attachment dispenses a 0.125 inch round bead and extends the reach of the gun, which helps when you are placing hot melt into corners, narrow channels, and patterned glue lines on production parts.

103R Extension Nozzle Benefits

• 0.125 inch round orifice helps operators lay down a smaller, more consistent bead for detail work.
• Extended tip geometry improves access into inside corners, deep channels, and recessed bond areas.
• Useful for wood components, packaging details, trim work, and general assembly where bead shape matters.
• Compatible with Chem-Set Pro Series hot melt guns, so crews can switch bead style without changing the full applicator.
• Metal nozzle construction stands up to repeated heat cycles in shop use.

Buyers typically add the 103R Extension Nozzle when the standard setup puts down too much adhesive or cannot reach the joint cleanly. A round extension tip helps keep squeeze-out down, improves line placement, and gives the operator better control on short runs, repair work, and repetitive bench assembly.

Common Applications for 103R Extension Nozzle

• Applying hot melt into grooves, rabbets, and narrow wood joints.
• Running controlled beads on packaging, displays, and light assembly fixtures.
• Reaching into inside corners on trim, countertop, and cabinet components.
• Detail adhesive placement on foam, fabric-backed parts, and small manufactured components.
• Reducing over-application where cleanup time or bond-line appearance matters.

Use and Safety Notes

Install or remove the tip only when the glue gun is hot enough for safe nozzle changeout, and use gloves with a wrench or pliers as the current product instructions recommend. Keep the orifice clean during production so the bead stays even from shot to shot, and confirm the nozzle is fully seated before returning the gun to the line.

Technical Details and Documentation
