The Bedford 55-1137 is a compatible replacement for DeVilbiss part MBD-12-K5, a springs for DeVilbiss spray equipment. This spring keeps its valve components loaded against their seats, so the valve closes crisply on every cycle instead of drifting or chattering. Spring steel fatigues gradually — tension loss shows up as inconsistent operation long before the spring visibly fails. Sold as a 5-pack, so spares stay in the service kit.

Common reasons for replacement:

  • Inconsistent valve action as spring tension fades
  • Ball or poppet chatter from a weakened spring
  • Collapsed or kinked coils found during teardown
  • Renewed as cheap insurance during any valve rebuild

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