What is Graco 178081 Plate, Tie?
The Graco 178081 Plate, Tie is a structural component used in Graco airless sprayer pump assemblies to secure and align tie rods within the pump body. It helps maintain uniform compression across the pump stack, ensuring stable high-pressure operation.
By reinforcing the pump’s internal structure, the tie plate prevents misalignment, reduces mechanical stress on seals, and supports consistent fluid delivery during demanding spraying applications.
Key Functions & Benefits
- Locks tie rods in correct alignment within pump assembly
- Distributes compression evenly across pump components
- Reduces vibration and internal mechanical stress
- Helps maintain seal integrity under high pressure
- Supports long-term durability of pump system
Role in Pump System
Installed within the upper pump structure, the Graco 178081 Plate, Tie ensures all tie rods remain evenly tensioned. This structural balance is essential for maintaining proper piston movement and preventing premature wear in high-pressure spray environments.
Frequently Asked Questions
It secures and aligns tie rods, ensuring even compression and structural stability inside the pump.
Yes, improper alignment or wear can lead to uneven pressure distribution and reduced spraying efficiency.
No, it is designed for specific Graco airless sprayer pump assemblies. Compatibility should be confirmed by model and pump type.
Failure can result in loss of structural integrity, uneven pressure, and potential damage to internal pump components.
