Abstract: A wiper device for oil well sucker rods is provided as an integral resilient body fabricated of an oil-resistant elastomeric composition. The resilient body is bounded in part by upper, lower and sidewall surfaces. A flat annular base portion extends inwardly from the sidewall surface. An interior portion of frustro-conical shape extends upwardly from the base portion and terminates in an orifice adapted to embrace the sucker rod. A reinforcing band is embedded within the base portion to provide structural stability.
