GRACO 198316 – 1/4″ NPT Retainer Nut

GRACO 198316 – 1/4″ NPT Retainer Nut

Function: Accessory nut / retaining nut for Auto-Plus valve

Port / thread compatibility: NPT threads (as a nut / retainer)

Application: Use in fluid/dispensing systems with extrusion tip requirements

If you are converting or outfitting an Auto-Plus valve to handle extrusion tips (rather than just spray or streaming tips), the 198316 is the component that properly retains the tip assembly. It’s especially important in setups where you switch between different tip types and need reliable performance without leaks or misalignment.
