What is the Graco MR8.5.70 .70 Thick Hardened Spacer?
The Graco MR8.5.70 .70 Thick Hardened Spacer 2.50 Od X 1.77 Id is a high-strength mechanical alignment component engineered for use in Graco MR series airless spray systems. It is designed to maintain exact spacing between critical internal assemblies, ensuring proper structural alignment under continuous high-pressure operation.
With a hardened construction and precise outer and inner diameter specifications, this spacer provides enhanced resistance to deformation, compression, and wear. It supports stable mechanical performance in demanding spraying environments where consistent alignment is essential for pump efficiency and fluid control accuracy.
This component is typically used in heavy-duty MR system assemblies where durability and tight tolerance control are required to maintain operational reliability and extend equipment lifespan.
Key Functional Role
- Maintains precise spacing within MR sprayer assemblies
- Supports alignment under high-pressure mechanical load
- Reduces vibration and internal component wear
- Improves long-term system stability and performance consistency
Frequently Asked Questions
