Oilfield Rubber Ball Plug for Swivel Joint and Pressure Testing Tools
Royal Way rubber ball plugs are engineered sealing components for completion, workover, drilling and production tools. Each element combines a carefully selected elastomer compound, controlled profile geometry and consistent molding quality to deliver a strong sealing interface in demanding well service.
Our Shanghai production team supports standard and custom rubber ball plug programs with responsive engineering, stable batch production and export-ready packaging. The design language follows API-style dimensional, material and service requirements used across modern oilfield tool assemblies.
Performance Highlights
- Pressure-ready ball plug sealing for reliable contact with casing and tubing surfaces
- NBR and HNBR compounds for broad temperature and fluid service programs
- Precision molded lips and support zones for smooth setting and retrieval
- Compound and hardness options coordinated with the customer tool drawing
- Black or custom color identification for organized field maintenance
