DISCONTINUED PRODUCT | Heavy Duty Water-Cooled Nozzles

DISCONTINUED PRODUCT | Heavy Duty Water-Cooled Nozzles

Effective February 27, 2026, the following nozzles will be discontinued due to low sales: 

  • 451-1-62 — 5/8″ bore, 1/4″ recess 
  • 451-61-62 — 5/8″ bore, flush recess 

These nozzles were used with 42-/45-series semi-automatic T-Guns and MW15-series fixed-automatic guns in water-cooled configurations. 

There is no direct Heavy-Duty replacement. However, 451-5-62 may be used as a Standard-Duty substitute for 451-1-62. No substitute is available for 451-61-62. 

Customers may transition to AccuLock™ R or Heavy Duty TOUGH LOCK™ consumables based on their gun series.
