Manufacturer: Total Finishing Supplies

Part Number: 337770

Comparable OEM Part Number: 112590

Description: Total Finishing's part # 17-2907 is a compatible replacement for GRACO® parts 112590 and 112-590, a throat packing set for GRACO® spray equipment. Packings are the stacked seal rings that ride the piston rod in the pump's fluid section, containing working pressure while the rod cycles through them thousands of times an hour. They are the pump's primary wear item. Compatible with GRACO® 7900 HD IronMan, 7900 HD ProContractor, APX 8200 (Chrome), APX 8200 (MaxLife), DutyMax, GH 200 and other GRACO® equipment.

Common reasons for replacement:

• Pump cycling faster than normal to hold pressure
• Scheduled repack on high-use equipment
• Pressure loss from worn packing surfaces
• Fluid climbing the rod or dripping from the throat area

Manufactured to OEM-equivalent dimensions for proper fit and performance.
