Pressure-Activated V-Style Sealing Solution for Graco Pump Systems
Compatible Machines
- Graco airless paint sprayer pump assemblies
- Graco piston pump fluid section systems
- Graco industrial coating and finishing equipment
- Graco high-pressure fluid handling systems
Used in pump sealing stacks where V-type packing is required to maintain pressure integrity and reduce fluid leakage during continuous high-pressure operation.
What is Graco 181662 Packing, Vee?
The Graco 181662 Packing, Vee is an OEM sealing component designed in a V-shaped configuration to create a dynamic, pressure-responsive seal inside Graco pump fluid sections. It compresses under pressure to prevent fluid leakage while allowing smooth movement of internal pump rods.
Engineered for demanding spray applications, it ensures stable pressure control, improved sealing efficiency, and reliable pump performance in industrial environments.
Key Functional Benefits
- Provides strong pressure-activated sealing performance
- Prevents fluid leakage in high-pressure pump systems
- Adjusts dynamically under changing pressure conditions
- Supports smooth rod and piston movement
- OEM design ensures precise Graco system compatibility
