Aftermarket GRACO® 157633 Replacement Spring, Lower Compression (Non-OEM)

Manufacturer: Total Finishing Supplies

Part Number: 472899

Comparable OEM Part Number: 157633

Description: Total Finishing's part # 23-1647 is a compatible replacement for GRACO® parts 157-633 and 157633, a spring for GRACO® spray equipment. This spring keeps its valve components loaded against their seats, so the valve closes crisply on every cycle instead of drifting or chattering. Spring steel fatigues gradually — tension loss shows up as inconsistent operation long before the spring visibly fails. Compatible with GRACO® 1:1 Fast-Ball and Standard Air Motor.

Common reasons for replacement:

• Ball or poppet chatter from a weakened spring
• Collapsed or kinked coils found during teardown
• Renewed as cheap insurance during any valve rebuild
• Inconsistent valve action as spring tension fades

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