The Bedford 18-1918 is a compatible replacement for Graco parts 186199 and 186-199, a backup washer for Graco spray equipment. A backup washer sits behind a seal or O-ring and gives it a rigid shoulder, preventing the softer seal from extruding into the clearance gap under pressure.

Common reasons for replacement:

  • Renewed together with the seal it backs
  • Adjacent seal or O-ring failing early from extrusion
  • Visible deformation or cupping of the washer
  • Pressure weep past a seal the washer should support

Manufactured to OEM-equivalent dimensions for proper fit and performance. Compatible Graco equipment models are listed in the Compatible Equipment section below, where available.
