Aftermarket GRACO® 15J566 Ring, Wear (Non-OEM)

Manufacturer: Total Finishing Supplies

Part Number: 46698

Comparable OEM Part Number: 15J566

Description: Total Finishing's part # 42-4139 is a compatible replacement for GRACO® parts 15J566 and 15J-566 — the ring; wear used in GRACO® spray equipment. A wear ring centers the piston in its cylinder and absorbs side-load rubbing, sacrificing itself so the piston and cylinder wall do not score. Compatible with GRACO® T2 2:1 Transfer Pump and T3 3:1 Transfer Pump.

Common reasons for replacement:

• Pressure loss from a piston running off-center
• Visible scoring or thinning of the ring at teardown
• Renewed during every piston service
• Piston contacting the cylinder wall as the ring wears through

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