Graco 15G689 Divider Quiet Manifold

Divider – Model 15G689 (Quiet Manifold)

The 15G689 DIVIDER, QUIET MANIFOLD is a precision engineered component designed to distribute fluid flow within a low-noise manifold assembly. Its design ensures smooth channeling of paint or coating material while reducing acoustic emissions and structural vibration—ideal for professional spraying systems where noise control and system reliability go hand in hand.

Applications & Functionality

This divider is used in industrial coating sprayers, large-capacity line-striping units or bulk fluid systems where a quiet manifold is required for compliant operation. It sits within the manifold housing, dividing the fluid passages while maintaining flow balance, structural integrity and minimal turbulence.

Key Specifications

Product Highlights

• Quiet design helps reduce audible noise in manifold systems, enhancing operator comfort.
• Precision machining ensures consistent alignment and minimal bypass between channels, improving coating quality.
• Durable construction built to withstand job-site conditions, repeated cycles and fluid turbulence.
• Direct replacement part to restore original manifold performance without redesign or modification.

Installation & Usage Guidelines

Prior to installation of the 15G689 divider, depressurize the system and isolate the manifold housing. Remove any existing divider components or inserts, clean the interior machining surfaces thoroughly, and inspect for wear or damage. Install the new divider ensuring it is properly seated and aligned with the manifold ports. Secure the housing cover or bolts to specification, then restore fluid flow slowly and monitor for consistent channeling, minimal noise and stable performance.

Maintenance & Care

• Periodically inspect the divider and manifold for signs of channel erosion, cracking or vibration-induced fatigue.
• Ensure the housing and divider interface remain clean and free of coating buildup or contamination that can alter flow or cause noise.
• Check that mounting fasteners and seals are secure and in good condition to maintain optimal performance.
