The GRACO 15D126 is a U-cup seal designed for use with shafts of .156 inch diameter. It is typically made from durable elastomeric materials such as Buna-N or similar compounds, intended to provide a reliable seal in GRACO spray equipment, preventing leaks and ensuring smooth operation of moving parts.

Key Features:

• U-cup seal
• 15D126, .156 shaft diameter
• Elastomeric (material not explicitly stated, but commonly Buna-N or similar in GRACO seals)
• Designed for GRACO spray equipment with .156 inch shaft diameter
• Fragile during installation—requires careful handling
• Designed for reliable sealing in dynamic applications
• Ease of maintenance: replaceable part

Applications:
Used in GRACO spray guns and similar equipment to seal shafts and prevent leaks, ensuring efficient and safe operation during spraying tasks.

Installation Notes:

• Using genuine GRACO parts ensures proper fit, performance, and longevity of equipment.
• Never pound on the seal during installation—use a small diameter (1/4 inch or smaller) object to gently push the seal into place
• Ensure the seal is seated properly against the sleeve bearing
• Remove old seal carefully using a hook-shaped object
• Replace associated seals, springs, and O-rings if necessary
