Frequently Asked Questions

Check your unit’s illustrated parts list (IPL) or service manual for the jam-nut line item. Match the part number to 102217. If your list shows a different nut (e.g., another jam-nut part number), use that instead.

Follow the torque specification in your pump’s service manual for the exact joint. If not specified, consult an authorized Graco distributor or service center before tightening.

For pressurized pump assemblies, OEM parts are recommended to ensure correct thread engagement, height, and durability. Using non-OEM hardware may affect performance or safety and can void warranties.

Use only if specified by your service manual. The jam-nut’s purpose is to mechanically lock the joint; additional compounds should follow OEM guidance to avoid over-locking or seizing.
