Graco 15H833 Ball Neo/SST Core 1.75

Compatible Machines

Product Overview

Upgrade your spray equipment with the **Graco 15H833 Ball Neo/SST Core 1.75″**, engineered for **optimal flow** and **long-lasting performance** in demanding applications. This precision component enhances fluid delivery and supports smooth operation for contractors relying on high-pressure sprayer systems.

• Optimized for high-pressure filtration
• Corrosion-resistant stainless steel body
• Precision-engineered ball mechanism for smooth operation

Built from durable stainless steel, it resists corrosion and maintains consistent output even under extreme pressure. Its low-friction design reduces wear on valves and hoses, ensuring sustained efficiency and reducing maintenance intervals across varied coating formulations.

Technical Specifications

Material Composition & Durability

The dual-material construction of the 15H833 ball integrates a neoprene-based elastomer ring precisely molded around a high-grade 316 stainless steel core. This design balances chemical compatibility (resisting bonding with solvents, acids, and particulate-laden coatings) with the mechanical resilience needed for sustained high-cycle pump operation.

During manufacturing, the stainless steel core undergoes a multi-stage heat treatment — solution annealing, cryogenic tempering, and passivation — to enhance corrosion resistance and hardness. The core is then diamond-ground to micron-level spherical accuracy, and the neoprene elastomer is vulcanized to the core for high preload stability (withstanding dynamic loads above 500 lbs). :contentReference[oaicite:4]{index=4}

Performance & Testing

Each 15H833 ball assembly undergoes rigorous bench testing to verify long-term reliability. It has been tested for over a million cycles under dynamic conditions, with no detectable wear, and survives static pressures up to 5000 psi. :contentReference[oaicite:5]{index=5}

Flow characterization tests show only a minimal pressure drop (5–7 psi) even at standard operating rates, confirming tight sealing and low friction. Particle-retention trials under microfiltration conditions also validate its efficacy for high-pressure filtration systems. :contentReference[oaicite:6]{index=6}

Application Insights

In real-world use, the **15H833 ball core** is ideal for integration into **diaphragm and piston pumps** handling solvent-borne, water-borne, and high-solid-content coatings. It performs well in architectural and industrial finishing, marine coatings, and specialty systems like UV-curable finishes. :contentReference[oaicite:7]{index=7}

Thanks to its rapid seating and low rebound, it also helps in reducing color changeover times and system purging, lowering material waste and downtime. Compatibility with rheology modifiers and abrasive pigment concentrates further enhances component life in continuous spray lines.

Installation & Maintenance

• Access the pump lower housing to replace the ball — it is seated in the check-valve assembly.
• Inspect all sealing surfaces for wear, particulate buildup, or extrusion before installing the new ball. :contentReference[oaicite:8]{index=8}
• Tighten the retaining jam nut to recommended torque (refer to the pump’s service manual).
• Clean every ~500 hours: disassemble, ultrasonically clean in non-abrasive detergent, and reassemble using a pre-filtration strainers (e.g., 40-micron) to minimize abrasive ingress. :contentReference[oaicite:9]{index=9}
