ABSTRACT:
An improved oil drain plug for engines and other machinery has a bored, generally cylindrical, first part with a threaded outer portion adapted to be inserted into an existing oil drain hole. A second, sealing part fits within the first and partially extends below it with a surface adapted to allow it to be manipulated in relation to the first. A pair of hooked slots on the first portion cooperate with a pair of protruding members on the second to form a "push and twist" type of engagement that allows a closed and opened configuration to be maintained by the device. A spout member is present on the first portion to allow the connection of a hose or tube for the convenient drainage of the oil into a container.
