Aftermarket GRACO® 176817 Retaining Spring, attach pin at top of piston rod (Non-OEM)
Manufacturer: Total Finishing Supplies
Part Number: 530451
Comparable OEM Part Number: 176817
Description: Total Finishing's part # 23-3251 is a compatible replacement for GRACO® parts 176817 and 176-817 — the retaining ring used in Graco spray equipment. Retaining rings snap into a machined groove and give components a hard axial stop — they are what keeps valve internals and pins from walking out of their bores under vibration. Compatible with GRACO® 390 st, GRACO® 390 sts, GRACO® 395 st, GRACO® 450 st, GRACO® 455 st, GRACO® 490 st and other compatible equipment.
Common reasons for replacement:
- Ring sprung or distorted during a previous removal
- Corrosion weakening the ring's grip in its groove
- Components shifting axially in their bore
- Renewed whenever the assembly is opened — they are one-use parts in practice
Manufactured to OEM-equivalent dimensions for proper fit and performance.
