Manufacturer: Total Finishing Supplies
Part Number: 742182
Comparable OEM Part Number: 247394(1)
Description: Total Finishing’s part # 17-2944 is a compatible replacement for GRACO® parts 247394 and 247-394 — the plug used in GRACO® spray equipment. This plug seals a machined service port on the pump body, closing off a passage that must hold full working pressure. Sold individually, so you can order exactly the quantity a service job needs. Compatible with GRACO® Xtreme 145cc (600) and Xtreme 180cc (750).
Common reasons for replacement:
- Weeping or seepage around the plug under working pressure
- Damaged threads or wrench flats after repeated service removal
- Deformation from over-torquing during reassembly
- Renewed as a matter of course during a rebuild
Manufactured to OEM-equivalent dimensions for proper fit and performance.
