ABSTRACT OF THE DISCLOSURE In a cone stuffing box for use on pumps of various kinds, particularly an oil well pump, there is described an annular sup- port member to prevent the deformation and consequent malfunction of the split rubber cones used to seal the polish rod reciprocat- ing through the stuffing box. In this invention, the support member comprises a rigid annular ring which is inserted into a recess formed into the bottom of the lowermost conical sealing member. The support member is formed with a bore hole to closely receive the piston rod. An upper surface of the ring engages and supports a surface of the recess and a lower surface of the ring is supported by the stuffing box housing. The support member re- inforces the conical seal and prevents the deformation thereof.
