  • Float assembly comes with included gasket (part number 100-010)
  • Up to 20% increased oil flow vs. older “1900-30” models, with decreased pressure drop across the float mechanism
  • Protective magnet to shield oil path from debris

100 % Compatible

The W4300-38F is a universal replacement, being 100% backwards-compatible with separators currently using the W1900-30 or the Henry A1900-30.
