Designing & Producing Long-Term Static Sealing Solutions

The JBL Division of Parker Hannifin’s Tech Seal Group fabricates extruded and precision-cut synthetic elastomer products, primarily used for static sealing applications. JBL products provide effective long-term sealing solutions for our customers. That’s because we use only the best “sealing grade” materials with the highest possible percentage of polymer. Many JBL elastomer compounds meet or exceed specialty-grade standards set by the FDA, ASTM, and other agencies. Our unique design geometry maximizes seal-surface contact, and our precision cutting gives the customer the seal they need, with superior consistency. Above all, we work closely with our customers to design the right seal for the application.
