Product Overview

The Graco 257655 Kit, Rod Piston, DP Ram is a genuine replacement component used to service and restore the performance of Graco dual-post ram assemblies. The piston rod plays a critical role in transferring force from the air-powered ram cylinder to the platen, allowing material to be efficiently pushed from drums and containers into the connected pumping system.

Replacing worn piston rod components helps maintain smooth ram movement, reliable pressure application, and consistent material flow in demanding industrial environments.

Key Features

• Genuine Graco replacement kit
• Designed for DP (Dual Post) Ram assemblies
• Helps restore proper ram operation and performance
• Supports efficient drum unloading and material transfer
• Suitable for high-viscosity material handling applications
• Built for demanding industrial environments

Typical Applications

• Industrial adhesives
• Sealants
• Mastics
• Heavy-bodied coatings
