Technical Description

The 16H032 Bar Shear Stop is a precision-engineered fluid section component designed to moderate shear forces in airless spray systems. By providing controlled resistance in fluid flow paths, it protects seals and internal components from premature wear and helps maintain consistent fluid delivery in demanding environments.

Installation & Usage Guide

• Before installation, ensure the sprayer is fully depressurized and powered off.
• Remove the old shear stop following the OEM parts diagram and service instructions.
• Install the new 16H032 part using correct torque settings and alignment procedures.
• Check for proper seating and fluid tightness before resuming operation.

Maintenance Recommendations

Inspect the shear stop during scheduled maintenance intervals. Clean debris from surrounding fluid passages and verify surface integrity. Replace if signs of metal fatigue or scoring are observed to prevent spray irregularities.

Safety Information

• Always relieve system pressure before servicing any fluid parts.
• Wear appropriate PPE, including eye protection and gloves.
• Avoid using abrasive cleaners that could damage the finish.
