Crane parts are very often difficult to identify because of their haphazard part number labeling. Many times Crane products will only have random manufacturing codes that make it difficult to identify which part you need. In the event that your item does not have a clear part number, use the dimensions and photos to match up a product.
Crane bought or merged with Universal Rundle at some point in its history, and during the transition period where both existed, some items were manufactured with either the name Crane or Universal Rundle on them. An example of this often occurs with 4471. This item is also confusing because sometimes it will be labeled 4471, 4471-4474, or 4474.
Crane was eventually bought or merged with American Standard, and had the same issue with duplicate products marked either Crane or American Standard.
