Frequently Asked Questions

Yes—100200 is an OEM Graco fitting nipple used where a 1/4-18 NPT male connector is specified in Graco assemblies.

Look up your sprayer’s parts manual. If the manual lists 100200 or calls for a 1/4-18 NPT nipple at that location, it is compatible. You can also compare the existing connector’s thread and length to this part.

NPT threads typically require an appropriate thread sealant (paste) or PTFE tape. Follow your Graco manual for approved sealants and torque specifications to ensure a leak-free connection.

The pressure capability depends on the machine and installation point. Verify your sprayer’s rated working pressure and ensure the fitting meets or exceeds that rating as specified in the manual for the location where it’s installed.

Common locations include the pump outlet, manifold / filter block, and hose adapter connections—anywhere two 1/4-18 NPT (female) components need to be joined.
