The Seal, Piston (Part Number 260386) is a genuine Graco replacement component designed to create a reliable seal between the piston and cylinder within compatible fluid handling equipment. It plays a critical role in maintaining pressure, preventing fluid bypass, and supporting efficient pump operation.
Manufactured to original Graco specifications, this piston seal helps ensure proper equipment performance while reducing the risk of leaks, pressure loss, and premature component wear. As an OEM replacement part, it delivers the fit and sealing integrity required for demanding industrial applications.
The piston seal forms a sealing barrier between moving pump components, allowing pressure to build efficiently during operation. A properly functioning seal helps maintain fluid control, improve pumping performance, and minimize internal leakage that can reduce system efficiency.
Over time, piston seals can wear due to friction, pressure cycles, and exposure to process materials. Replacing worn seals with genuine Graco components helps restore pressure performance, reduce leakage, and extend the service life of the equipment.
