Royal Way 5-1/2 in light-load V-type swab cups pair a flexible NBR lip with a steel-core base for large-bore casing and tubing fluid-recovery programs. The 5.5 in cup adds a dedicated size reference for operators and service companies building swab strings for lighter-load well-service work, while the flexible V profile provides a clear replacement option for maintenance and repeat supply. Jiangsu Ruowei Energy Technology Co., Ltd. manufactures molded oilfield rubber products at its Haimen facility in Nantong, Jiangsu.
The nominal size identifies the product family, while the working-cup OD and core opening show the listed molded dimensions for this configuration.
