Description
The Bedford 18-1992 is a compatible replacement for Airlessco part 331-021, a female adapter for Airlessco spray equipment. The female adapter sits at the end of the packing set in the pump’s fluid section, seating the packings squarely so they seal against the piston rod and cylinder wall. Worn adapters let the stack shift, and no amount of packing-nut tightening will hold pressure once that happens.
Common reasons for replacement:
- Pressure loss that new packings alone do not cure
- Wear or corrosion on the adapter’s seating face
- Renewed with the packing set during a fluid-section repack
- Fluid bypassing a packing stack that no longer sits square
Manufactured to OEM-equivalent dimensions for proper fit and performance. Compatible Airlessco equipment models are listed in the Compatible Equipment section below, where available.
