3/8-24 lock nut for Graco dispensing equipment. Secures hose connections and mounting assemblies. Standard replacement part for field maintenance.

Frequently Asked Questions
Can't find your answer?
Contact UsWhat is the GRACO NUT, LOCK 3/8-24?
A 3/8-24 UNF lock nut used to secure hose assemblies, nozzle swivels, and mounting hardware on Graco fuel dispensing equipment. Standard replacement part for field maintenance.
Will this fit my Graco nozzle or pump?
Check your existing hardware for 3/8-24 thread. This is a standard Graco OEM part and fits any 3/8-24 threaded assembly in their dispensing range.
How many should I keep on hand?
Depends on your fleet. Lock nuts get replaced during hose swaps or after cross-threading. At $3.80 each, keeping 5-10 in the workshop costs less than one unplanned trip to the supplier.
What is the warranty and how do I get support?
12-month warranty against factory defects. Fasteners are wear items subject to torque and handling. For questions or bulk orders, contact sales@goind.com.au or 07 3204 2240.
