Abstract
A drip ring for use with a hydraulic cylinder is provided. The drip ring is prefabricated from a flexible material. To size the prefabricated drip ring, the drip ring is cut and wrapped around the hydraulic cylinder that is to be fitted. The amount of excess drip ring material is measured and removed. The properly sized drip ring is then placed around the cylinder such that the two cut edges are positioned within a bonding fixture that has been pre-filled with a bonding compound. The inner flange of the drip ring is secured against the hydraulic cylinder with an adjustable, metal restraining strap. If desired, a drain fixture coupled to a drain pipe is attached to the fitted drip ring.
