Product Description

The Graco 15C894 Fluid Needle Guide is a precision-machined OEM component designed for use within select Graco fluid control assemblies. It guides the fluid-needle to ensure accurate positioning and sealing during spray operations, supporting reliable flow regulation and consistent finish quality.

Key Features & Benefits

• OEM-specified part number ensures compatibility and fit within Graco gun or sprayer fluid assemblies
• Precisely engineered guide bore for smooth needle travel and minimal play, improving control feel
• Durable construction resists wear from repeated needle actuation and aggressive coatings
• Helps maintain proper alignment of the fluid needle, reducing leakage or spray irregularities
• Cost-effective replacement part to restore factory performance of the fluid control system

Technical Specifications

Applications & Practical Use

• Used when rebuilding or servicing the fluid control system of spray guns or sprayers to restore smooth needle motion and sealing.
• Helps maintain consistent spray shut-off and eliminates leaking or dribbling when the needle isn’t centering correctly.
• Ideal for contractors and service technicians performing maintenance on Graco equipment in coatings, texture, or finishing environments.
• Useful preventive-maintenance replacement when the fluid needle feels loose, drips, or produces inconsistent atomization performance.

Maintenance & Replacement Tips

• When servicing the gun or sprayer, inspect the guide bore for wear, scoring or ovalization as this can affect needle alignment.
• Clean the guide and surrounding bore area of dried coating or debris before re-assembly to ensure smooth needle travel.
• Use recommended torque values and follow manufacturer instructions during re-assembly of the fluid needle and guide to maintain performance.
• If upstream performance issues persist after installing a new guide (such as fluid leaks or spray irregularity), check the needle tip, seat and packing for wear or damage.
