The GRACO 17H191 is a piston seat kit that includes an O-ring, designed for use in GRACO equipment such as the ToughTek® mortar pumps (Legacy F340e series). The kit is intended to provide a reliable seal and smooth operation for the piston assembly, ensuring efficient and leak-free performance in demanding industrial applications. The material is not specified, but typical piston seats are made from durable plastics or engineered composites, while O-rings are usually elastomeric for sealing.
