A stuffing box assembly comprising a body which has a bore defined by a generally cylindrical wall and a shaft extending concentrically through the bore. A sleeve is disposed in the bore in surrounding relationship to the shaft, the sleeve havfng a cylindrical portion and an annular flange, the sleeve defining an annulus between the cylindrical portion and the wall defining a bore. At least one and preferably several annular members formed of an elastomeric material are disposed in the annulus. Astop means limits movement of the annular member away from the flange portion of the sleeve, the annular members being disposed between the flange portion and the stop means. One or more seals or packings for sealing between the shaft and the wall are disposed between the shaft and the wall on the opposite side of the flange portion from the annular member. An adjustable packing gland or the like urges the seal or packings against the flange portion of the sleeve such that the annular member is compressed and exerts a reactive force against the flange portion, the annular members also serving to form a seal between the wall and the cylindrical portion of the sleeve.
