Parker Spiral Vee Rings are precision-formed rubber and combination rubber/fabric sealing products designed to protect equipment from leakages and costly down time. These rings are manufactured using a single-step process that molds the entire spiral length of the product at one time. This process dramatically reduces scrap, and eliminates the potential for variations in hardness caused by over or under-curing at an overlap area. Once cured, the spiral length is pre-formed onto mandrels of varying diameters. Parker spiral vee rings are designed to work in combination with adapters and shims. Adapters, which typically consist of rubber or plastic rings, are fitted to the top and/or bottom of the vee ring stack to enhance sealing performance and prohibit extrusion. Rectangular cross-section discs, or “shims,” are used to adjust the height of the vee ring stack set to pre-existing groove depths.
