The Titan 770-181 Hex Jam Nut is a genuine OEM replacement fastener used on HVLP AirSpray Quart Cups and ProFinish TS40/TS50 sprayers. Jam nuts are thinner than standard nuts and are typically used to lock another nut in place or to secure components in tight spaces.
A missing, stripped, or corroded jam nut can cause loosening of critical assemblies, leading to air leaks, fluid leaks, or misalignment of spray head components. Replacing with the correct specification nut restores secure fastening and reliable equipment operation.
