One of the most commonly used types of lubricators is certainly the spherical straight lubricator. The lubricator consists of a mouthpiece for a lubricator in a spherical shape. We call this ball lubricator straight, because we put the lubrication press on the head in a straight direction, i.e. in the axis of rotation of the thread of the lubricator. Lubricants are manufactured according to the DIN 71412 standard.
