Chem-Set 101 Nozzle Assembly Check Valve

Description

101 nozzle assembly is the Chem-Set check valve component used between a compatible hot melt glue gun and the working nozzle tip. It helps secure the nozzle connection, supports cleaner shutoff, and gives production benches a replaceable wear part for glue guns that start to drip or lose bead control.

101 nozzle Benefits

• Check valve design helps reduce unwanted dripping after the trigger is released.
• Threaded accessory format lets crews replace a worn valve instead of retiring the full glue gun.
• Compatibility with PRO Series style hot melt nozzles supports flat, round, needle, and specialty tip setups.
• Small spare part is easy to keep at each packaging, assembly, or repair station.
• Hot melt gun maintenance helps protect finished surfaces from excess adhesive drops.

Use this assembly when a compatible gun needs a new valve body before the final nozzle. It is especially useful for teams changing between bead shapes or keeping several tip styles ready for packaging, display, woodworking, and countertop support tasks.

101 nozzle Applications

• Replacing worn check valve assemblies on compatible hot melt glue guns.
• Supporting flat, round, needle, and specialty nozzle changes at the bench.
• Reducing drip complaints during carton sealing, trim placement, and small assembly jobs.
• Keeping repair stock for production stations that run hot melt daily.
• Preparing glue guns before switching between adhesive stick types or bead profiles.

Setup And Handling

Warm the glue gun fully before removing or installing the valve assembly. A cold nozzle connection can be tight with cooled adhesive and may damage threads if forced. Wear heat-resistant protection, keep hands away from the outlet, and make the change on a stable bench.

After installation, purge a small amount of adhesive through the gun before returning it to production. Confirm the final nozzle is seated, the bead shape is consistent, and adhesive flow stops cleanly enough for the job.
