322012 322014 322016 322018 Single Orifice Hot Melt Nozzle Single Hole Straight Bead Hot Glue Dispensing Nozzle

• Fixed part numbers 322012, 322014, 322016, and 322018 are dedicated single orifice nozzles for hot melt adhesive gun modules.
• Original factory structural design and dimension calibration ensure 100% seamless matching without any modification.
• Standard threaded installation structure assembles perfectly with the gun body, greatly reducing equipment maintenance downtime.
• Color-coded sealing rings enable quick model identification, convenient for warehouse inventory sorting and on-site part replacement.
• Standard industrial batch coding, highly recommended for global distributors, glue dispensing workshops, and OEM accessory suppliers.

• Engineered to form a precise, consistent straight glue bead with stable flow rate according to different orifice diameters.
• Delivers uniform glue bead thickness, eliminating dripping, uneven glue output, or intermittent dispensing during continuous running.
• Ideal for carton sealing, product assembly, hygiene products, book binding, and workpieces requiring neat linear glue lines.
• High compatibility with various hot melt adhesives, including EVA hot melt glue, polyolefin glue, and PUR hot melt adhesive formulations.

• Main body manufactured from high-grade brass with excellent thermal conductivity and high temperature resistance, adapting to long-time high-temperature working environments.
• Precision hardened steel needle tip for long service life, resisting abrasion caused by continuous hot glue scouring.
• Ultra-smooth inner flow channel reduces glue residue accumulation, less prone to coking and blockage under continuous production.
• Strong corrosion resistance against different types of hot melt adhesives, suitable for long-cycle industrial continuous dispensing.

• Precision machined thread and sealing ring structure guarantees an airtight fit, preventing hot melt glue leakage at the connection.
• Avoids glue dripping, stringing, and leaking during equipment standby or working status.
• Compact hexagonal outer profile, easy to tighten and disassemble with a standard wrench for field replacement.
• Modular split design enables fast disassembly for internal channel cleaning, convenient for glue type switching and daily maintenance.

A reliable, high-performance replacement nozzle that keeps hot melt dispensing lines running efficiently while lowering overall maintenance and part replacement costs.
