Sealing Solutions for Design Engineers
Solve complex sealing challenges with custom inflatable seals engineered for demanding pressure, temperature, chemical, and geometric requirements.
When seal performance is critical to the entire system, an off-the-shelf solution may not be enough. Seal Master Corporation works with mechanical, design, and product engineers to develop custom, fabric-reinforced inflatable seals tailored to the specific geometry, environment, and performance requirements of an application. Fabric reinforcement gives our seals the strength to handle higher pressures and repeated inflation cycles, so they work harder and last longer than standard elastomer seals.
From complex geometries to demanding pressure, temperature, motion, and chemical exposure, our engineering team solves sealing challenges across aerospace, defense, nuclear, pharmaceutical, medical, energy, and industrial equipment.

Inflatable Seals Engineered Around Your Application
A seal isn't an isolated component. Its geometry, materials, operating pressure, inflation direction, mounting method, environment, and surrounding equipment all influence how it performs.
For engineers working on mission-critical or highly regulated systems, that means seal selection has to begin with the application itself.
Seal Master Corporation supports engineers developing equipment for:
Typical applications include:
- Aerospace
- Defense
- Nuclear
- Pharmaceutical
- Medical equipment
- Energy applications
- Industrial machinery
- OEM products
- Custom equipment and systems
Whether you're starting with a new design or addressing a failure in an existing system, our engineers can help evaluate the sealing challenge and develop a solution around your performance requirements.
Sealing Challenges Design Engineers Face
Complex applications can quickly expose the limitations of standard sealing products.
Design engineers may need to account for:
- Seal failure under pressure, motion, or temperature extremes
- Complex or unconventional geometries
- Limited installation or mounting space
- Chemical or environmental exposure
- Repeated cycling and long-term durability requirements
- Material and regulatory requirements
- Integration with surrounding equipment
- Insufficient technical data or validation
- Lengthy custom prototyping and design cycles
When existing products don't meet those requirements, Seal Master Corporation provides custom engineering support to help solve the problem at the application level.
Performance Factors to Consider in Inflatable Seal Design
Successful seal design depends on how multiple engineering variables interact. Addressing those factors early can help reduce unnecessary design iterations and identify potential performance issues before production.
Geometry and Cross Section
Available mounting space, required stroke, direction of inflation, bend radius, and mating surfaces all influence seal geometry.
Seal Master Corporation has developed an extensive library of inflatable seal cross sections, including snap-in, bond-in, encapsulated, fasten-in, and recessed-groove profiles. When an existing profile doesn't meet the application's requirements, our engineers can develop a custom configuration.
Pressure and Motion
Operating pressure, pressure differential, movement, and cycling requirements affect how an inflatable seal needs to be constructed and reinforced.
Fabric reinforcement helps provide structural integrity and dimensional stability, allowing the seal to maintain controlled geometry under demanding conditions.
Temperature and Environment
Operating temperatures and environmental conditions can significantly affect elastomer performance. Understanding both normal and extreme conditions (like extreme heat or extreme cold) helps determine the appropriate material selection and seal construction for the application.
Chemical Compatibility
Exposure to oils, fuels, solvents, process chemicals, water, or other substances must be considered during materials selection.
Seal Master Corporation engineers evaluate application requirements to determine the appropriate combination of elastomer and fabric reinforcement rather than relying on a one-material-fits-all approach.
Installation and Retention
Groove geometry, available space, inflation direction, and retention method can affect both seal performance and serviceability. Evaluating these variables during the design process can help avoid integration issues later.
How Seal Master Corporation Supports the Engineering Process
Collaborative Design & Engineering
Our design and engineering team works directly with engineers to understand the complete application, not simply a requested seal dimension.
Application drawings or CAD files, pressure requirements, temperature ranges, chemical exposure, installation constraints, cycle requirements, and performance goals can all help guide development.
Fabric-Reinforced Construction
Seal Master Corporation's fabric-reinforced inflatable seals are engineered to provide strength, dimensional stability, and controlled inflation in demanding applications.
Rather than relying on an unsupported elastomer alone, reinforcement helps control expansion and maintain the intended seal geometry under pressure.
Custom Geometry
When a standard seal cannot accommodate your geometry, Seal Master Corporation can develop a custom profile around the available space, required movement, mounting method, and sealing surface.
Our existing cross-section library can also provide a starting point for design and modification.
Application-Specific Materials
Seal Master Corporation uses combinations of elastomers and fabric reinforcement selected according to the geometric and environmental demands of the application.
Material selection is based on application-specific factors such as temperature, chemical exposure, pressure, movement, and performance requirements.
Design Validation & Development
Our custom engineering capabilities support the development of custom sealing solutions from initial design through production. Our engineering team works with customers to evaluate application requirements, refine the seal design, and address potential performance or integration concerns.
This collaborative approach can help reduce unnecessary design iterations and develop a sealing solution around the requirements of the application.
Frequently Asked Questions
Yes. Nearly every seal we produce is engineered specifically for the customer's application, including custom dimensions, shapes, and cross sections.
Application drawings or CAD files are helpful, along with operating pressures, temperature ranges, chemical exposure, installation constraints, cycle requirements, performance expectations, and applicable regulatory requirements. Existing seals, samples, or photographs may also help when evaluating a replacement application.

Yes. Material selection for both the seal and the fabric reinforcement is based on the application's environmental and mechanical requirements. Seal Master Corporation engineers evaluate factors such as temperature, chemical exposure, pressure, abrasion, geometry, and required performance to recommend an appropriate combination of elastomer and reinforcement.
Not necessarily. Seal Master Corporation has developed an extensive library of inflatable seal profiles. An existing cross section may meet your requirements or provide a starting point that can be modified for your application. If an existing profile isn't appropriate, our team can develop a custom solution.
Yes. Seal Master Corporation works with customers throughout the development process to evaluate application requirements and refine custom sealing solutions. The specific development and validation process depends on the application and its performance requirements.
Seal Master Corporation develops sealing solutions for demanding applications across industries including aerospace, defense, nuclear, pharmaceuticals, medical, energy, and industrial equipment.
Featured Engineering Project
Cask Seal for Spent Nuclear Fuel Rods
Seal Master Corporation developed a custom inflatable seal for spent nuclear fuel storage casks where the seal needed to hold water in place under significant heat and pressure.
The engineering team used a custom G-1 cross section manufactured from EPDM for heat and radiation resistance. Variations between individual casks also required extensive testing to verify proper seal inflation and fit, with Seal Master Corporation engineers providing on-site testing and installation support.
