Abstract
A wiper (200a) for a blowout preventer having an adapter ring (102a) and a piston (104a) slideable relative to the adapter ring along an interface can include a base (202) adapted to couple the wiper to the adapter ring and a head (204) coupled to the base. The head can include a first portion adapted to bridge the interface and contact the piston and a second portion adapted to contact the adapter ring and support the first portion. The second portion of the head can be adapted to at least partially resist rotation of the wiper. A blowout preventer can include one or more wipers as shown and described.
