Abstract
A stripping element for rotary flow control diverters used in the oil and gas industry can include a stiffening member formed of a first harder material than a deformable member formed of a second softer material over-molded to the stiffening member. The stiffening member can include apertures that provide for the second softer material of the deformable member to be displaced through the apertures when a pipe of a drill is displaced through the stripping element. The stiffening member can include multiple members that stiffen the deformable member to prevent the deformable member from bending into the stripping element when a pipe of a drill is displaced through the stripping element. The multiple members can be displaced out in a direction away from the pipe of the drill when the pipe of the drill is displaced through the stripping element to prevent the stripping element from being compromised.
