From standard extrusion profiles to fully custom-engineered solutions — every seal we manufacture is designed to solve a specific application challenge.
Answer 3 quick questions and we'll point you to the right product.
Non-reinforced inflatable seals are the most versatile and cost-effective inflatable sealing solution for standard applications. Produced as extrusions bonded into custom shapes, these seals can be made straight, as endless loops, or with molded corners at any angle. Dynamic Rubber can produce virtually any cross-section profile and bond it into any geometry your application requires.
When inflated, the seal expands against a mating surface to create an airtight, watertight, or gas-tight barrier. When deflated, it fully retracts — making it ideal for applications requiring repeated access such as clean room doors, autoclave chambers, and medical sterilizers.
Fabric reinforced inflatable seals are fully molded seals built around the same operating principles as homogeneous inflatable seals, but with internal fabric reinforcement that dramatically increases pressure capacity. The reinforcement layer allows these seals to withstand higher internal pressures, survive heavier loads, and deliver consistent uniform operation over thousands of cycles in demanding environments.
DRI can match any competitor's cross-section profile or engineer a custom reinforced seal from scratch. If your application requires a non-enclosed retainer environment, extreme cycle life, or exposure to aggressive chemicals and temperatures, fabric reinforcement is the right solution.
Dynamic Rubber manufactures nuclear inflatable seals for PWR steam generator isolation, reactor coolant system maintenance, and critical outage applications. Our dual-seal design — a wet seal and a dry seal — provides passive fail-safe redundancy that keeps systems isolated without relying on active monitoring.
Engineered to custom bore sizes and manufactured from nuclear-grade elastomers qualified for RCS chemical and radiation environments, our seals enable parallel refueling and steam generator maintenance — saving 5–14 days of critical-path outage time per steam generator.
DRI manufactures custom inflatable bladders for composite molding processes and industrial tooling applications. These bladders apply uniform internal pressure inside composite layups during cure cycles, ensuring consistent wall thickness and void-free laminates across complex 3D geometries. Compatible with both autoclave and out-of-autoclave manufacturing processes.
Dynamic Rubber manufactures FDA-compliant inflatable seals for pharmaceutical and food processing applications where hygiene, chemical resistance, and temperature performance are critical. Our seals create airtight perimeters around smokehouse doors, retort vessels, autoclave doors, clean rooms, and processing tanks — preventing contamination while reducing heat loss and improving processing yield.
All compounds are selected to resist steam, smoke, and the harsh cleaning chemicals used in sanitary environments. EPDM and Silicone options are available, along with standard profiles and custom geometries to fit your specific equipment.
DRI manufactures inflatable seals across the full size spectrum. Our precision miniature seals are engineered to the tight dimensional tolerances required by semiconductor process chambers and medical equipment, with low-outgassing compounds available for clean room and vacuum applications. Custom profiles for confined or complex geometries are available.
For large diameter applications, we produce non-reinforced seals via continuous cure extrusions, with long seals available via splicing in both reinforced and non-reinforced configurations. Segmented tooling is available to fully mold any size. Applications range from vacuum and airtight sealing to clamping, lifting, and uniform pressure bonding.
A complete inflatable seal system requires more than just the seal itself. DRI supplies a full range of accessories to ensure proper installation, reliable inflation, and secure retention — all matched to your specific seal configuration and application requirements.
