5.5 Inch V Type Oilfield Swab Cup for Light-Load Well Service
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.
