Material integrity dictates sealing longevity. Our EC sealing plugs are formulated in either high-grade NBR or FKM to match specific environmental demands. NBR offers exceptional resistance to petroleum-based oils, hydraulic fluids, and mechanical wear, making it the industry standard for general industrial applications. For environments characterized by elevated temperatures or aggressive chemical exposure, our FKM variant delivers superior thermal stability and chemical inertness. Both compounds are engineered to resist ozone degradation and compression set, ensuring the cap maintains its radial tension over extended service cycles.

Designed with practical maintenance in mind, the EC type rubber sealing plug allows for rapid installation without the need for complex shaft disassembly or specialized press tools. The rubber-covered OD accommodates slightly scratched or imperfections in housing bores, ensuring a tight seal without strict machining tolerances. Because it functions as a static cap, it eliminates the frictional wear and heat generation associated with moving lips, leading to a virtually maintenance-free operational lifespan. Replacement is straightforward, minimizing equipment downtime during routine system overhauls.
