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.


Getting Started: Cross Sections

Your needs require a custom inflatable seal, but where do you start? Our newly redesigned cross sections page will help get you started. The dozens of inflatable seal profiles are only a representation of some of the typical profiles used and are not representative of all of the special profiles Seal Master has created over our 40 year history. Our cross sections page can be used as a tool to align your needs with our capabilities.

Quality Control: Our Inspection Process

Quality Built Quality Tested

At Seal Master we take pride in our products and stand by their quality. Each Seal Master product is inspected a minimum of two times prior to shipment by two separate Seal Master Quality inspectors. During this process inspectors are looking for obvious cosmetic defects but are also trained to be aware of other problems that may occur during operation. Below are examples of some inspection processes that take place prior to shipment. 

Cross Section Spotlight: Snap in Type

Snap-in type inflatable seal profiles utilize our uniquely designed dovetail base that enables the seal to simply "snap" into a matching retainer groove. The retainer groove provides support and protection for the seal. Installation and replacement is quick and easy. For more information on snap in types please visit our Seals 101 page.
