Seal Master

Feature: Seal Master Materials

When you choose to work with Seal Master, you are working with a manufacturer that values the quality of the materials used to create inflatable seals and rubber. Our products are only as good as the materials we use, and we go to great lengths to ensure our materials are of the best quality.

Material Selection, Selected for You

Our inflatable seals are not simple extrusions. Each seal is custom engineered and molded specifically for each client’s needs to ensure optimum performance for long-term operation. 

Applying Holding Force

If you are searching for a way to properly and safely block, brake, or clamp objects in your operation, an inflatable seal from Seal Master can help.

Hold Force

One of the multiple ways our seals help customers in countless industries is through applying hold force. 

By applying hold force, our seals can hold objects in place with even pressure and then release them as required by your application. An inflatable seal can deliver adequate hold force on delicate objects which may be fragile or stop objects in place. 

G12 Miter Corner Seal

Seal Master is an industry leader at designing and manufacturing custom engineered, fabric reinforced inflatable seals for a variety of applications. One such seal is a miter corner seal. 

How The Miter Corner Seal Works

The Miter Corner Seals from Seal Master can take on several different shapes and measurements. But overall the seal is meant to fill gaps and protect one environment from outside contaminants. 

A corner seal is designed to situate around corners and inflate properly simply with air pressure. 

Inflatable Seal Options: Seal It!

Our inflatable seals are designed to provide even pressure along a specific object. While this pressure can be used to push, stop, lift, or hold objects in place, it can also be used to create a hermetic seal and provide a barrier between two different environments. 

Creating a Seal

Our handcrafted fabrication utilizes both heat and pressure along the entire structure in order to bring out the best qualities of the elastomer. With our fully molded, fabric reinforced construction, these seals are leak proof, offering great structural integrity and durability. 

Learn About the Benefits of a Custom Engineered Seal

While Seal Master’s product catalog features over 7,500 items, you may be in need of a product that hasn’t been created yet. 

What is a Custom Engineered Seal? 

Built to size using materials your project demands, our inflatable seals use liquid, water, or gas to inflate. The seal fills the area to the exact shape needed, creating a perfect fit. 

With our fabric-reinforced and fully-molded design, our inflatable seals can withstand millions of duty cycles. Seal Master inflatable seals are designed and constructed with quality and durability in mind from the start. 

Reduce Downtime & Save Money

Downtime in any production line can cause delays in meeting deadlines. But it can also cost manufacturers money. 

Is Downtime Really Necessary? 

There are instances where downtime for specific machines or production lines may be necessary, for example, when machines need calibrated. Routine maintenance is crucial to prolong the lifespan of the equipment. 

Quality Matters to Us

The Seal Master Corporation didn’t develop its reputation overnight as a quality, custom engineered manufacturer of inflatable seals and other rubber products. But quality has always been our goal since the beginning.


Our sealing systems are included in a variety of applications. Some are as large as sealing massive hangar doors at America’s Satellite Program in Cape Canaveral, or as small as a collar to harness laboratory mice. 


Learn More About Seal Master and What We Do!

Founded in 1974, Seal Master Corporation has built itself into an industry leading manufacture of custom engineered, hand built, fabric reinforced inflatable seals and other manufactured rubber products.


Edward L Bittle founded the company after many years spent at B.F. Goodrich, in the height of the Akron, Ohio rubber industry. But once Ed saw a niche market he could fill, he started his own company to provide quality, custom rubber products.


How Do Reinforced Inflatable Seals Work?

Since 1974, Seal Master has been the leader in product development and engineering advances in the realm of reinforced inflatable seals. The firm’s products have been featured in countless applications such as industrial, environmental, military uses.


But what exactly is an inflatable seal? And what does it do?


In countless high-tech applications, there are times when consistent, constant pressure needs to be introduced in order to push, lift, squeeze, stop, hold, or seal materials.
