What is Graco 24E974 Kit, EP, Piston, Rear?
The Graco 24E974 Kit, EP, Piston, Rear is an OEM-grade rear piston component used in Graco EP gun and applicator systems. It is a precision-engineered internal part responsible for maintaining controlled fluid movement within the piston assembly. This component works in coordination with other critical elements such as the 24E972 front piston, 24E973 bulkhead, and multiple sealing O-rings to ensure consistent pressure regulation and smooth coating delivery.
Designed for durability under high-pressure conditions, the rear piston plays a key role in reducing wear, preventing leakage, and ensuring stable operation in professional spray applications. It is typically used as part of a full piston rebuild system within Graco EP applicator assemblies.
Function & Importance
- Maintains rear-end sealing integrity inside the piston assembly
- Ensures consistent fluid pressure during spray operation
- Works with front piston and O-ring system for controlled displacement
- Reduces wear in high-cycle industrial spraying environments
