Precision-engineered nylon piston for Graco PR70 systems, delivering accurate 2K material metering and consistent volumetric control in high-demand dispensing applications.
The Graco LCB800 Pr70 Piston, S, 800, Nyl, 31.92Mm is a precision metering piston designed for use in Graco PR70 dispensing systems. It regulates material flow within the pump assembly to ensure accurate ratio control in high-performance two-component dispensing applications. The “800” sizing indicates its displacement class, while the 31.92Mm diameter ensures precise mechanical fit within compatible PR70 piston chambers.
Manufactured from durable nylon (NYL), this piston is engineered for low-friction operation, chemical resistance, and long service life in demanding industrial environments such as adhesive bonding, sealing, and epoxy dispensing.
This component is part of the Graco PR70 piston package system, responsible for controlling volumetric displacement during metering cycles. It works in coordination with the pump’s drive mechanism to deliver precise, repeatable output. Each piston size in the PR70 range is matched to specific system configurations to maintain consistent mixing ratios and dispensing accuracy.
