Graco 287817 Pump Cylinder Sleeve Replacement for GH733 and King Series Airless Sprayers Aftermarket by Bedford 57-3851
The Bedford 57-3851 Pump Cylinder Sleeve is a precision aftermarket replacement for the Graco 287817 Sleeve used in Graco GH733 and King Series industrial airless sprayers.

Ideal for contractors who demand consistent output and long service intervals, this Bedford replacement delivers OEM-level durability at a lower cost while maintaining full compatibility with Graco systems.
