Description
The Bedford 17-3878 is a compatible replacement for Graco parts 189314 and 189-314, a shim for Graco spray equipment. Shims set precise clearance between assembled components — stacking or removing them is how the factory-specified end-play and preload are dialed in.
Common reasons for replacement:
- Wear or compression changing the set clearance
- Lost during teardown — small parts with outsized consequences
- Renewed whenever the assembly is re-shimmed to spec
- Incorrect stack-up after a rebuild missing a spacer or shim
Manufactured to OEM-equivalent dimensions for proper fit and performance. Compatible Graco equipment models are listed in the Compatible Equipment section below, where available.
