Historical Bendix/Facet Breathers

Purolator Facet, Inc. continues to build several breathers that were formerly manufactured under the Bendix, Facet or Purolator brand names. These breathers were supplied to mobile equipment OEM's for use on hydraulic reservoirs. Although no longer in production, these breather caps are ordered to service older vehicles in the field.
