5-1/2 Inch Sand-Service Oilfield Swab Cup with Metal Core
Royal Way 5-1/2 in Sand-Service swab cup is a large-format V-type oilfield cup for tubing and casing swab-tool assemblies. Its molded elastomer body and metal-core opening bring the working cup profile and reinforced center into one field-service component for sand-bearing well operations, maintenance programs and replacement inventory.
Jiangsu Ruowei Energy Technology Co., Ltd. manufactures oilfield rubber products at its Haimen facility in Nantong, Jiangsu, China. Buyers can coordinate the 5-1/2 in cup with the equipment model, preferred compound, hardness and service plan for a focused product program.
