Accessories must be purchased separately.

Use only GENUINE GRACO PARTS AND ACCESSORIES.

WARNING

NEVER operate your equipment at a working pressure rating that is higher than the lowest rated component in
your system. Lower rated components may not be able to withstand the pressure developed by the pump and may
rupture, causing serious bodily injury or property damage.
