Design & Durability
This hi‑collar lock spring washer is built to stabilize fastening systems under intense cyclical loading. The elevated collar ensures increased surface engagement, enhanced contact with mating components and improved resistance to axial displacement and loosening due to vibration.
Performance in Spray Systems
Installed in critical clamp assemblies and drive housings of high‑output sprayers, this washer maintains preload, avoids fastener backlash and contributes to overall system integrity. Using the 106115 washer helps extend service intervals and supports consistent equipment performance.
Installation & Maintenance
Replace the washer any time the associated fastener is serviced or removed. Ensure the mating surface is clean and flat before installation. Torque the fastener to the specification recommended by the equipment manual, and verify that the collar seats fully. Inspect at regular service intervals for wear or deformation—replace if the collar is flattened or lost its spring‑action.
Quality Assurance
Manufactured under stringent production controls, each washer undergoes dimensional verification, hardness testing and corrosion screening. Compatibility with Graco’s high‑cycle spray systems ensures OEM‑level performance and fit.
