Description
The Bedford 18-3550 is a compatible replacement for Graco part 18209, a retainer for Graco spray equipment. Retaining rings snap into a machined groove and give components a hard axial stop — they are what keeps valve internals and pins from walking out of their bores under vibration.
Common reasons for replacement:
- Renewed whenever the assembly is opened — they are one-use parts in practice
- Ring sprung or distorted during a previous removal
- Corrosion weakening the ring’s grip in its groove
- Components shifting axially in their bore
Manufactured to OEM-equivalent dimensions for proper fit and performance. Compatible Graco equipment models are listed in the Compatible Equipment section below, where available.
